In article number 1501721, the effect of donor and acceptor energetic disorder on the open‐circuit voltage loss in organic bulk heterojunction (BHJ) solar cells is determined by Thuc‐Quyen Nguyen and co‐workers. It is demonstrated that disorder loss depends strongly on morphology and the donor acceptor pairing, where as much as 0.2 V in Voc loss can be attributed purely to excess energetic disorder.
