Hanwha Qcells, a subsidiary of South Korea’s Hanwha Corp has set a world record for tandem solar cell efficiency. The company’s innovative M10-sized cell, featuring a perovskite-silicon structure, reached an impressive efficiency of 28.6%.
This incredible output surpasses the 27% efficiency of crystalline silicon cells and the 21% typical of standard commercial solar panels. They achieved this milestone just one year after starting large-scale tandem development, promising project size and cost reduction.
Danielle Merfeld, Global CTO at Hanwha Qcells.
“The tandem cell technology developed at Hanwha Qcells will accelerate the commercialization process of this technology and, ultimately, deliver a great leap forward in photovoltaic performance,” said “We are committed to advancing the next generation of solar energy efficiency and will keep investing significantly in research and development to drive progress in this field, as every kilowatt counts on the path to building a more sustainable future.”
Hanwha Qcells Redefines Solar Efficiency
The press release mentioned that the R&D team began groundwork in 2016 to develop a commercially feasible tandem solar cell using perovskite top-cell technology and Hanwha Qcells flagship silicon bottom-cell technology.
Eventually, in 2019, the solar giant launched an advanced research center in Pangyo, Korea that would complement their well-established R&D hub in Bitterfeld-Wolfen, Germany. After achieving success with small-area tandem cells, the focus shifted to large-area designs that finally culminated in the record-breaking 28.6% tandem solar cell efficiency.
Designing the Future of Solar
The certified record was verified by the CalLab at the Fraunhofer Institute for Solar Energy Systems (ISE). The high efficiency comes from an innovative design that pairs a perovskite-based top cell with Hanwha Qcells’ proprietary Q.ANTUM silicon bottom-cell technology.
This measurement, taken on a full-area M10-sized cell (approximately 0.36 square feet or 330.56 cm²) used a standard industrial silicon wafer that could be interconnected into an industrial module. The tandem technology stacks a perovskite top cell and a silicon bottom cell to optimize energy capture. Simplifying the technique, the top cell absorbs high-energy light while low-energy light passes through to the bottom cell to maximize power output per module.
So, what’s the advantage? Well, fewer panels generate the same power, which further reduces costs and land use for solar projects.
Significantly, Hanwha Qcells developed this tandem technology with commercial manufacturing in mind. They are focused on going beyond lab-scale demonstrations. With their scalable processes and tools, the company is all geared up for the next generation of efficient, cost-effective solar energy solutions.
Thus, this milestone moves the solar industry closer to the widespread commercialization of more powerful and affordable solar technology.
Robert Bauer, Head of Hanwha Qcells R&D in Germany noted,
“Hanwha Qcells is excited to announce this new world record in tandem cell efficiency based on our in-house developed perovskite technology as a top cell, and cost-efficient Q.ANTUM silicon technology as a bottom cell. The champion cell is a typical cell from our R&D pilot line in Germany and has been fabricated exclusively using processes that are feasible for mass production. This result is laying the groundwork for future commercialization of this exciting technology.”

Collaborative initiatives like the EU’s PEPPERONI project have further fueled progress.
Danielle Merfeld also added,
“We are fortunate to have outstanding global R&D teams and to have received invaluable support from our partners in Korea and Europe, leveraging their resources and expertise. We deeply appreciate everyone dedicated to driving innovations that bring us closer to achieving our climate goals.”

DOE Backs Qcells with $1.45 Billion Loan for Solar Supply Chain
The U.S. Department of Energy’s (DOE) Loan Programs Office (LPO) has finalized a $1.45 billion loan to support Qcells’ solar manufacturing facility in Cartersville, Georgia. Initially, in August 2024, DOE announced it as a conditional commitment but with this confirmation, the funding will help build a robust solar supply chain in the U.S.
The company noted that over the past decade, solar installations have surged. The U.S. alone had over 5 million installations, with a target of reaching 10 million by 2030. According to the U.S. Solar Market Insight 2023 Year in Review, total U.S. solar capacity is projected to hit 673 GW by 2034, enough to power over 100 million homes.
Furthermore, the IEA’s Renewables 2024 report predicts that global renewable energy will add 5,500 GW of capacity by 2030, with solar PV technologies driving 80% of this growth.

Energizing U.S. Solar Innovation
Qcells, a global leader in solar solutions and the largest silicon-based solar panel producer in the Western Hemisphere plans to invest $2.8 billion in this groundbreaking project. The Cartersville facility will produce ingots, wafers, cells, and panels on a multi-gigawatt scale.
Furthermore, on completion, the plant will have a production capacity of 8.4 GW, or approximately 46,000 solar panels per day. Rebuilding these critical parts of the domestic solar supply chain is a huge contribution to the U.S. energy independence and reduced carbon emissions.
Hanwha’s Commitment to Net Zero
Hanwha Solutions 2050 Net Zero goals align with the global target of limiting temperature rise to below 1.5°C. As per its latest sustainability report, it plans to cut Scope 1 and 2 emissions by 35% by 2030 and 60% by 2040, using 2018 as the baseline.

Some strategies include:
- improving energy efficiency
- adopting renewable energy
- utilizing by-product hydrogen as fuel
- incorporating carbon capture and utilization (CCU) technologies
The solar giant also purchases renewable energy through KEPCO’s Green Premium program. In 2023, the Chemical Division secured 53.7 GWh, and the Qcells Division obtained 27 GWh.
Notably, Qcells maximizes on-site renewable energy generation. Solar panels installed on rooftops and parking lots now produce 3.9 MW, with plans to add 2 MW in 2024. Last year, these facilities supplied 3.2 GWh of clean energy.
In conclusion, the DOE’s loan is a testament to the solar industry’s vital role in helping American manufacturers compete globally and succeed long-term. And Hanwha Qcells is just doing the job right. It’s advancing scalable manufacturing and high-efficiency solar cells, driving affordable and sustainable solar solutions.

How Climate Change Is Raising the Cost of Living
Americans are paying more for insurance, electricity, taxes, and home repairs every year. What many people may not realize is that climate change is already one of the drivers behind those rising costs.
For many households, climate change is no longer just an environmental issue. It is becoming a cost-of-living issue. While climate impacts like melting glaciers and shrinking polar ice can feel distant from everyday life, the financial effects are already showing up in monthly budgets across the country.
Today, a larger share of household income is consumed by fixed costs such as housing, insurance, utilities, and healthcare. (3) Climate change and climate inaction are adding pressure to many of those expenses through higher disaster recovery costs, rising energy demand, infrastructure repairs, and increased insurance risk.
The goal of this article is to help connect climate change to the everyday financial realities people already experience. Regardless of where someone stands on climate policy, it is important to recognize that climate change is already increasing costs for households, businesses, and taxpayers across the United States.
More conservative estimates indicate that the average household has experienced an increase of about $400 per year from observed climate change, while less conservative estimates suggest an increase of $900.(1) Those in more disaster-prone regions of the country face disproportionate costs, with some households experiencing climate-related costs averaging $1,300 per year.(1) Another study found that climate adaptation costs driven by climate change have already consumed over 3% of personal income in the U.S. since 2015.(9) By the end of the century, housing units could spend an additional $5,600 on adaptation costs.(1)
Whether we realize it or not, Americans are already paying for climate change through higher insurance premiums, energy costs, taxes, and infrastructure repairs. These growing expenses are often referred to as climate adaptation costs.
Without meaningful climate action, these costs are expected to continue rising. Choosing not to invest in climate action is also choosing to spend more on climate adaptation.
Here are a few ways climate change is already increasing the cost of living:
- Higher insurance costs from more frequent and severe storms
- Higher energy use during longer and hotter summers
- Higher electricity rates tied to storm recovery and grid upgrades
- Higher government spending and taxpayer-funded disaster recovery costs
The real debate is not whether climate change costs money. Americans are already paying for it. The question is where we want those costs to go. Should we invest more in climate action to help reduce future climate adaptation costs, or continue paying growing recovery and adaptation expenses in everyday life?
How Climate Change Is Increasing Insurance Costs
There is one industry that closely tracks the financial impact of natural disasters: insurance. Insurance companies are focused on assessing risk, estimating damages, and collecting enough revenue to cover losses and remain financially stable.
Comparing the 20-year periods 1980–1999 and 2000–2019, climate-related disasters increased 83% globally from 3,656 events to 6,681 events. The average time between billion-dollar disasters dropped from 82 days during the 1980s to 16 days during the last 10 years, and in 2025 the average time between disasters fell to just 10 days. (6)
According to the reinsurance firm Munich Re, total economic losses from natural disasters in 2024 exceeded $320 billion globally, nearly 40% higher than the decade-long annual average. Average annual inflation-adjusted costs more than quadrupled from $22.6 billion per year in the 1980s to $102 billion per year in the 2010s. Costs increased further to an average of $153.2 billion annually during 2020–2024, representing another 50% increase over the 2010s. (6)
In the United States, billion-dollar weather and climate disasters have also increased significantly. The average number of billion-dollar disasters per year has grown from roughly three annually during the 1980s to 19 annually over the last decade. In 2023 and 2024, the U.S. recorded 28 and 27 billion-dollar disasters respectively, both setting new records. (6)
The growing impact of climate change is one reason insurance costs continue to rise. “There are two things that drive insurance loss costs, which is the frequency of events and how much they cost,” said Robert Passmore, assistant vice president of personal lines at the Property Casualty Insurers Association of America. “So, as these events become more frequent, that’s definitely going to have an impact.” (8)
After adjusting for inflation, insurance costs have steadily increased over time. From 2000 to 2020, insurance costs consistently grew faster than the Consumer Price Index due to rising rebuilding costs and weather-related losses.(3) Between 2020 and 2023 alone, the average home insurance premium increased from $75 to $360 due to climate change impacts, with disaster-prone regions experiencing especially steep increases.(1) Since 2015, homeowners in some regions affected by more extreme weather have seen home insurance costs increased by nearly 57%.(1) Some insurers have also limited or stopped offering coverage in high-risk areas.(7)
For many families, rising insurance costs are no longer occasional financial burdens. They are becoming recurring monthly expenses tied directly to growing climate risk.
How Rising Temperatures Increase Household Energy Costs

The financial impacts of climate change extend beyond insurance. Rising temperatures are also changing how much energy Americans use and how utilities plan for future electricity demand.
Between 1950 and 2010, per capita electricity use increased 10-fold, though usage has flattened or slightly declined since 2012 due to more efficient appliances and LED lighting. (3) A significant share of increased energy demand comes from cooling needs associated with higher temperatures.
Over the last 20 years, the United States has experienced increasing Cooling Degree Days (CDD) and decreasing Heating Degree Days (HDD). Nearly all counties have become warmer over the past three decades, with some areas experiencing several hundred additional cooling degree days, equivalent to roughly one additional degree of warmth on most days. (1) This trend reflects a warming climate where air conditioning demand is increasing while heating demand generally declines. (4)
As temperatures continue rising, households are expected to spend more on cooling than they save on heating. The U.S. Energy Information Administration (EIA) projects that by 2050, national Heating Degree Days will be 11% lower while Cooling Degree Days will be 28% higher than 2021 levels. Cooling demand is projected to rise 2.5 times faster than heating demand declines. (5)
These projections come from energy and infrastructure experts planning for future electricity demand and grid capacity needs. Utilities and grid operators are already preparing for higher peak summer electricity loads caused by rising temperatures. (5)
Longer and hotter summers also affect how homes and buildings are designed. Buildings constructed for past climate conditions may require upgrades such as larger air conditioning systems, stronger insulation, and improved ventilation to remain comfortable and energy efficient in the future. (10)
For many households, this means higher monthly utility bills and potentially higher long-term home improvement costs as temperatures continue to rise.
How Climate Change Affects Electricity Rates
On an inflation-adjusted basis, average U.S. residential electricity rates are slightly lower today than they were 50 years ago. (2) However, climate-related damage to utility infrastructure is creating new upward pressure on electricity costs.
Electric utilities rely heavily on above-ground poles, wires, transformers, and substations that can be damaged by hurricanes, storms, floods, and wildfires. Repairing and upgrading this infrastructure often requires substantial investment.
As a result, utilities are increasing electricity rates in response to wildfire and hurricane events to fund infrastructure repairs and future mitigation efforts. (1) The average cumulative increase in per-household electricity expenditures due to climate-related price changes is approximately $30. (1)
While this increase may appear modest today, utility costs are expected to rise further as climate-related infrastructure damage becomes more frequent and severe.
How Climate Disasters Increase Government Spending and Taxes
Extreme weather events also damage public infrastructure, including roads, schools, bridges, airports, water systems, and emergency services infrastructure. Recovery and rebuilding costs are often funded through taxpayer dollars at the federal, state, and local levels.
The average annual government cost tied to climate-related disaster recovery is estimated at nearly $142 per household. (1) States that frequently experience hurricanes, wildfires, tornadoes, or flooding can face even higher public recovery costs.
These expenses affect taxpayers whether they personally experience a disaster or not. Climate-related recovery spending can increase pressure on public budgets, emergency management systems, and infrastructure funding nationwide.
Reducing Climate Costs Through Climate Action
While this article focuses on the growing financial costs associated with climate change, the issue is not only about money for many people. It is also about recognizing our environmental impact and taking responsibility for reducing it in order to help preserve a healthy planet for future generations.
While individuals alone cannot solve climate change, collective action can help reduce future climate adaptation costs over time.
For those interested in taking action, there are three important steps:
- Estimate your carbon footprint to better understand the emissions connected to your lifestyle and activities.
- Create a plan to gradually reduce emissions through energy efficiency, cleaner technologies, and more sustainable choices.
- Address remaining emissions by supporting verified carbon reduction projects through carbon credits.
Carbon credits are one of the most cost-effective tools available for climate action because they help fund projects that generate verified emission reductions at scale. Supporting global emission reduction efforts can help reduce the long-term impacts and costs associated with climate change.

Carbon credit project stewardship: what happens after credit issuance
A carbon credit purchase is not a transaction that closes at issuance. The credit may be retired, the certificate filed, and the reporting box ticked. But on the ground, in the forest, in the field, and in the community, the work continues. It endures for years. In many cases, for decades.
