Abstract

We investigated the role of pentacene in inverted polymer solar cells based on the blends of poly(3-hexylthiophene) (P3HT), (6,6)-phenyl C₆₁-butyric acid methyl ester (PCBM), and pentacene. The performance of organic solar cells with pentacene improved in terms of power conversion efficiency (PCE), thermal stability, and lifetime in the ambient air. The pentacene in the P3HT:PCBM blends modified the crystallization of P3HT and PCBM. The donor-acceptor interface of devices with pentacene was found to be more stable than that without pentacene in the active layer, which was characterized by optical microscopy, atomic force microscopy and ultraviolet-visible absorption spectra. The PCE of pentacene based as-fabricated device was 4.3%, and the PCE of non-encapsulated pentacene device reduced just by about 25% after 4 months.
