Abstract

The image features a polymer solar cell with a graphene oxide (GO) hole-extraction layer and a GO–Cs electron-extraction layer to efficiently convert solar light into electricity at low cost. By tuning the GO work function through charge neutralization of its carboxylic acid groups to afford GO–Cs, a single material system is demonstrated as both hole- and electron-extractio layers for high-performance solar cells. For more information please read the paper by L. Dai and co-workers, beginning on page 2228.
