In article number 1606909 , Ming‐Fai Lo, Chun‐Sing Lee, and co‐workers report unusual free‐carrier generation in some bipolar organic materials (SubNc and SubPc) upon photoexcitation. Single‐layer devices with SubNc or SubPc sandwiched between two electrodes can give power conversion efficiencies 30 times higher than previously reported single‐layer devices. Interestingly, these photoactive layers can be stacked onto each other with any sequence to generate a photocurrent in OPV devices.
