Abstract

The alloy acceptor (indene-C₆₀ bis-adduct (ICBA)/[6,6]-phenyl-C₇₁ -butyric acid-methyl-ester (PC₇₁ BM)) is employed to replace the widely used fullerene acceptor (PC₇₁ BM) in organic solar cells based on five different polymer donors, which exhibit a higher efficiency and much better device stability than the PC₇₁ BM counterpart.

Keywords: alloy acceptors; binary acceptors; organic solar cells; stability; ternary blends.
