Sol-gel processed MoO(x) (sMoO(x)) hole-extraction layers for organic solar cells are reported. A Bis(2,4-pentanedionato)molybdenum(VI)dioxide/isopropanol solution is used and only a moderate thermal post deposition treatment at 150 °C in N(2) ambient is required to achieve sMoO(x) layers with a high work-function of 5.3 eV. We demonstrate that in P3HT:PC(60)BM organic solar cells (OSCs) our sMoO(x) layers lead to a high filling factor of about 65% and an efficiency of 3.3% comparable to that of reference devices with thermally evaporated MoO(3) layers (eMoO(3)). At the same time, a substantially improved stability of the OSCs compared to devices using a PEDOT:PSS hole extraction layer is evidenced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
