Oxford PV says it has set a new world record for most efficient solar panel, produced in collaboration with the Fraunhofer Institute for Solar Energy Systems. 

The panel achieved a 25% conversion efficiency, an increase from the more typical 24% efficiency of commercial modules, the company added.

Oxford PV, a spin-out of the University of Oxford, is developing perovskite-on-silicon tandem solar cells, which have a theoretical maximum efficiency of more than 43%.

“Our record-breaking solar panels demonstrate that we are on the cusp of the next solar revolution, which will be delivered, in part, by our tandem cell technology,” says Chris Case, Oxford PV CTO.

“Solar energy is currently among the most cost-effective and sustainable energy sources. Our continuous advancements in technology will further enhance module efficiency, producing more electricity from the same area, and extending their use to all market sectors from residential, commercial through to utility scale.”

Bravery Meets Tragedy: An Unending Story

Published

Here’s a story:

He had 3 days left until graduation.

STEM School Highlands Ranch. May 7, 2019.

Kendrick Castillo was 18. A robotics student. College bound. Accepted into an engineering program. The final week of school felt like countdown, not crisis.

Then a weapon appeared inside a classroom.

Students froze.

Kendrick did not.

Witnesses say he moved instantly. He lunged toward the attacker. No hesitation. No calculation.

Two other students followed his lead.

Gunfire erupted.

Kendrick was fatally sh*t.

But his movement changed the room.

Classmates were able to tackle and restrain the attacker until authorities arrived. Investigators later stated that the confrontation disrupted the attack and likely prevented additional casualties.

In seconds, an 18-year-old made a decision most adults pray they never face.

Afterward, the silence was heavier than the noise.

At graduation, his name was called.

His diploma was awarded posthumously. The arena stood in collective applause. An empty seat. A cap and gown without the student inside it.

His robotics teammates remembered him as curious. Competitive. Kind. Someone who solved problems instead of avoiding them.

He had planned to build machines.

Instead, he built a moment.

A moment that classmates say gave them time.

Time to escape.

Two points:

If you can read this without tears welling up in your eyes, you’re a far more stoic person than I.

Since Big Money has made it impossible for the United States to implement the same common-sense gun laws that exist in the rest of the planet, this story will reduplicate itself into perpetuity.

How often does this happen? How about never?

Trump loves to say that little boys go to school and come back home little girls.

He’s the most powerful person in the world for exactly one reason: We’re a nation of morons.

Illegal Aliens and U.S. Veterans

Two comments:

That the United States has homeless veterans is a national (and international) disgrace.

By definition, no one has the legal right to enter the U.S. illegally, but according to our constitution, everyone in America is entitled to due process.
