Potassium-induced surface modification of Cu(In,Ga)Se2 thin films for high-efficiency solar cells

Compared with their rigid counterparts, thin-film solar cells grown on flexible substrates usually display lower power-conversion efficiencies. Now, the application of a post-deposition alkaline treatment that modifies the chemical composition of the surfaces of Cu(In,Ga)Se 2 thin films reduces opti...
