An effective method for reducing interelectrode shorting in silver nanowire (AgNW) based organic solar cells is reported. The method is applied to standard and inverted devices based on poly(3‐hexylthiophene) and [6,6]‐phenyl‐C 61 ‐butyric acid methyl ester. The best results are obtained using an inverted architecture with a 200 nm buffer layer of nanostructured titania (TiO x ) on top of the AgNWs, yielding power conversion efficiencies of up to 3.5%.
