Semi-transparent organic photovoltaics are highly expected for building-integrated applications. To improve their efficiency, it is essential to develop top transparent electrodes with both high visible-light transmittance and conductivity. In this study, we investigated a composite electrode combining silver nanowires (AgNWs) with SELFTRON, a self-doped conducting polymer using ethanol as a solvent, which enables film fabrication inside a glove box. This approach successfully suppressed organic layer damage and leakage currents, which are common issues for conventional water-based AgNW electrodes, resulting in favorable rectification characteristics. Furthermore, by incorporating a MoO3 interlayer and a busbar electrode, we successfully reduced series resistance and achieved a power conversion efficiency of 4.05%.
