Evolution Inspires More Efficient Solar Cell Design: Geometric Pattern Maximizes Time Light Is Trapped in Solar Cell

"Researchers at Northwestern University have now developed a new design for organic solar cells that could lead to more efficient, less expensive solar power. Instead of attempting to increase efficiency by altering the thickness of the solar cell's polymer layer -- a tactic that has preciously garnered mixed results -- the researchers sought to design the geometric pattern of the scattering layer to maximize the amount of time light remained trapped within the cell."
