摘要：

In this work, the way in which ambient moisture impacts the photovoltaicperformance of conventional PCBM and emerging polymer acceptor–basedorganic solar cells is examined. The device performance of two representative p-type polymers, PBDB-T and PTzBI, blended with either PCBM orpolymeric acceptor N2200, is systemically investigated. In both cases,all-polymer photovoltaic devices processed from high-humidity ambientconditions exhibit significantly enhanced moisture-tolerance compared totheir polymer–PCBM counterparts. The impact of moisture on the blendfilm morphology and electronic properties of the electron acceptor (N2200vs PCBM), which results in different recombination kinetics and electrontransporting properties, are further compared. The impact of more comprehensive ambient conditions (moisture, oxygen, and thermal stress) onthe long-term stability of the unencapsulated devices is also investigated.All-polymer solar cells show stable performance for long periods of storagetime under ambient conditions. The authors believe that these findingsdemonstrate that all-polymer solar cells can achieve high device performance with ambient processing and show excellent long-term stabilityagainst oxygen and moisture, which situate them in an advantageous position for practical large-scale production of organic solar cells.
