We report on the use and stability of solution‐processed molybdenum oxide (sMoO x ) thin films as anode‐modifying layers to replace conventionally used poly(3,4‐ethyldioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) layers in poly(3‐hexylthiophene):[6,6]‐phenyl C 61 butyric acid methyl ester (P3HT/PC 61 BM) bulk heterojunction organic solar cells. Our results show that while as prepared devices using the two anode‐modifying layers possess similar performances, the sMoO x devices exhibit a staggering 20‐fold stability improvement in its performance half‐life compared with PEDOT/PSS devices, ~3400 h versus ~150 h, respectively. A further comparison of the stability between encapsulated and unencapsulated devices demonstrates the necessity for protection from atmospheric moisture and oxygen but again highlights the lucrative nature of sMoO x as a protective anode‐modifying layer compared with PEDOT/PSS even under ambient conditions.

In this manuscript, we show life time comparison between P3HT/PCBM organic solar cell devices using PEDOT/PSS or MoOx thin films as anode modifying layer, fabricated on indium tin oxide‐coated glass substrates with normal device architecture using indium tin oxide as anode and aluminum as cathode. The devices with solution processed MoOx show a staggering 20 times improvement in the life times over those fabricating using conventional PEDOT/PSS layers.
