Abstract Solar cells fabricated from a blend of the conjugated polymers poly(3-hexylthiophene) (P3HT) and poly(9,9-dioctylfluorene-co-benzothiadiazole) (F8BT) demonstrate a substantial improvement in power conversion efficiency ( η ) upon the addition of pristine graphene to the active layer. Cells display complex dependence on graphene concentration, and a maximum of three-fold enhancement in performance. This increase is entirely due to the higher short circuit current ( J sc ), since the… CONTINUE READING
