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.
