Evolution Inspires More Efficient Solar Cell Design: Geometric Pattern Maximizes Time Light Is Trapped in Solar Cell
The sun's energy is virtually limitless, but harnessing its electricity with today's single-crystal silicon
solar cells
is extremely expensive -- 10 times pricier than coal, according to some
estimates. Organic solar cells -- polymer solar cells that use organic
materials to absorb light and convert it into electricity -- could be a
solution, but current designs suffer because polymers have less-than-optimal electrical properties.
