Abstract

Abstract : Insulating Bi2 O3 nanoparticles are used for structuring the rear metal electrode in polymer solar cells creating a localized geometric electric field enhancement. In combination with the localized cells formed under the nanoparticles which are operating at short condition, the nanostructured electrode edges improve the overall charge extraction resulting in an overall power conversion efficiency gain of ≈30%.
