New solar cell captures double the amount of energy from the sun

A lot of people are excited about solar energy, and with good reason: It’s clean, renewable, and as manufacturing capabilities ramp up, an increasingly realistic way to power our world. On April 30th, 2017, Germany met 85% of its power needs from renewable energy sources including solar panels. Still, solar cells currently capture only about 25% of the available solar energy. Now a team from GW School of Engineering and Applied Science has produced a remarkably designed solar cell that collects nearly half of it. It’s been believed that the upper limit for the efficiency of conventional solar cells is about 30%, so this could be a big deal.

Scientists at GW School of Engineering and Applied Science have designed a multi-layered, stacked cell that operates as a sort of “solar sieve.” Each layer grabs a portion of the light spectrum as sunlight passes through on its way to the next layer down.
