Analysis of measured charge‐carrier mobilities and fill factors in solution‐processable small‐molecule bulk‐heterojunction solar cells reveals that in order to achieve a high FF, the hole and electron mobilities must be >10 −4 cm 2 V −1 s −1 . Neat‐film mobility measurements are also found to be a useful predictor of the maximum blend film mobility and FF obtained in blend film solar cells.
