Stanford researchers claim the inherent disordered molecular structure of polymer semiconductors is actually desirable. Current organic solar cells made with semiconducting polymers try to mimic orderly silicon structures as much as possible; this direction of research may be fundamentally wrong according to the Stanford researchers. A balance between molecular order and disorder at the polymer semiconducting interface is required; if
Solar cells that mimic leaves put organic systems back in the picture
As solar cells, and obviously the solar energy sector in consequence, become ever more popular spurred by increased demand through out the world, scientists today are currently interested in two major keypoints: increasing efficiency – the most important and immediate goal at hand – and making solar cells as cheap as possible without, obviously, compromising quality (solar conversion efficiency). Solar
