Abstract

In this paper, the optoelectronic properties and morphological features of indium-free ZnO/Ag/MoOx electrodes deposited by in situ combination of RF and DC sputtering at room temperature for low-cost organic photovoltaics has been discussed. The transparent composite electrode (ZnO/Ag/MoOx) was optimized by inspecting the formation of a continuous Ag thin film on top of the ZnO layer. It was found that a 9 nm thick Ag film had the best Haacke figure of merit. Organic solar cells on these composite electrodes revealed good optical and electrical properties, making them a promising alternative indium-free and PEDOT:PSS-free organic solar cells.
