Title: Functional interlayers of fullerene derivatives and applications in organic solar cells

Abstract

The invention provides novel materials, methods and designs to enable improved power conversion efficiencies of organic photovoltaics (OPVs). In particular, the invention provides novel materials and interlayers for polymer-based solar cells. Novel functional fullerene-based interlayers are disclosed that enable high efficiency devices in conjunction with numerous active layer and electrode materials.
