Abstract

The performance of bulk-heterojunction solar cells fabricated from a donor-acceptor structured polymer designed to exhibit the color green (PGREEN) as the electron-donor, along with [6,6]-phenyl-C71 butyric acid methyl ester (PC₇₀BM) as the electron-acceptor, are demonstrated with power conversion efficiency (PCE) up to 3.2% under air mass 1.5G, 100 mW/cm². The effects of anode interface layers (PEDOT:PSS, MoO₃) and different acceptors (PC₆₀BM, bis-PC₆₀BM, PC₇₀BM) on the cell performance were investigated. We found that the combined effect of PC₇₀BM and a MoO₃ anode interlayer exhibits a 69% enhancement in PCE compared to cells with PEDOT:PSS and PC₆₀BM. This enhancement in PCE is attributed to combined effects of improved charge transport and strong light absorption by PC₇₀BM, and efficient hole extraction by the MoO₃ interlayer.
