Power conversion efficiencies in excess of 7 % have been achieved with bulk heterojunction (BHJ)‐type organic solar cells using two components: p‐ and n‐doped materials. The energy level and absorption profile of the active layer can be tuned by introduction of an additional component. Careful desig...
