Deciphering the effect of replacing thiophene with selenophene in diketopyrrolopyrrole (DPP)-based low cost hole transport materials on the performance of perovskite solar cells

Abstract

Diketopyrrolopyrrole (DPP)-based low-cost hole-transporting materials are designed via facile approaches for efficient perovskite solar cells, which endowed impressive PCE over 16% along with ambient stability.
