Organic optoelectronic devices and materials with increased efficiency and lifetime

Abstract

An organic photovoltaic (OPV) device comprises a first arrangement of at least one OPV cell, and a second arrangement of at least one OPV cell, wherein the first and second arrangements are connected in parallel. An organic photovoltaic device comprises a substrate, a first and second electrodes above the substrate, and a heterojunction between the electrodes, comprising a first and second regions, wherein at least a portion of the heterojunction is lightly doped, wherein a conductivity dopant is covalently tied to a host within the first or second regions.
