Semprius Sets a New Concentrated Solar Efficiency Record with 33.9%!

Semprius Sets a New Concentrated Solar Efficiency Record with 33.9%!

First Time that More Than 1/3 of Sun's Energy is Converted to Electricity Making solar panels that are as efficient as possible at turning sunlight into electricity is very important. It's a way to bring costs down (you need fewer solar cells for a given output) and keep the footprint of solar installations to a minimum. It's a long and arduous process of incremental improvement, and each tenth of a percentage point is hard fought.The latest efficiency record was achieved for concentrating solar (you make sunlight go through lenses or curved mirrors to multiply its intensity) by a startup called Semprius . Their technology uses lenses to concentrate the sun's rays on tiny but very high-performance solar panels. The actual solar cells might only be a few square millimeters, but the lenses provide them with light that is as intense as 1,100 suns, so what they lack in surface...
