In article 1604044, T. Wang and co‐workers report compositional and surface modifications to low‐temperature‐processed TiO 2 films as electron transport layers in inverted polymer solar cells. This approach not only increases the power conversion efficiency of photovoltaic devices to 10.5%, but more importantly, eliminates the light‐soaking problem that is commonly observed in polymer solar cells employing metal oxides as the charge‐transport layers.
