“…Our observation is in agreement with Dettinger et al, who have observed two new carbonyl vibrations upon photooxidation of PC 60 BM in O 2 , one at 1784 cm À1 and one, that appeared after larger photon doses, at 1854 cm À1 , together with the pristine ester carbonyl of the PC 60 BM side chain at 1735 cm À1 . 35 Analogously, two new carbonyl peaks have also been reported by Yamane et al 62 on indene-C 60 monoadduct and indene-C 60 bisadduct fullerene derivatives that do not have a carbonyl in the side chain. FTIR peaks at 1725 cm À1 and 1785 cm À1 were also found by Wohlers et al for thermally oxidized C 60 27,63 and assigned to an anhydride structure.…”

“…Nonetheless, the impact of moisture on the degradation of fullerenes under ambient conditions has been rarely noticed. Moreover, only a few works investigated the air stability of OSCs containing fullerene derivatives . Among the nonfullerene acceptors, polymer acceptors are advantageous, including improved thermal and mechanical stability, enhanced absorption coefficient, as well as tunable electronic and chemical properties relative to fullerene acceptors .…”

In this work, the way in which ambient moisture impacts the photovoltaic performance of conventional PCBM and emerging polymer acceptor-based organic solar cells is examined. The device performance of two representative p-type polymers, PBDB-T and PTzBI, blended with either PCBM or polymeric acceptor N2200, is systemically investigated. In both cases, all-polymer photovoltaic devices processed from high-humidity ambient conditions exhibit significantly enhanced moisture-tolerance compared to their polymer-PCBM counterparts. The impact of moisture on the blend film morphology and electronic properties of the electron acceptor (N2200 vs PCBM), which results in different recombination kinetics and electron transporting properties, are further compared. The impact of more comprehensive ambient conditions (moisture, oxygen, and thermal stress) on the long-term stability of the unencapsulated devices is also investigated. All-polymer solar cells show stable performance for long periods of storage time under ambient conditions. The authors believe that these findings demonstrate that all-polymer solar cells can achieve high device performance with ambient processing and show excellent long-term stability against oxygen and moisture, which situate them in an advantageous position for practical large-scale production of organic solar cells.
