| Popis: | We report on the use and stability of solution-processed molybdenum oxide (sMoOx) 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 C61 butyric acid methyl ester (P3HT/PC61BM) bulk heterojunction organic solar cells. Our results show that while as prepared devices using the two anode-modifying layers possess similar performances, the sMoOx 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 sMoOx as a protective anode-modifying layer compared with PEDOT/PSS even under ambient conditions.
