Improving the compatibility of fullerene acceptors with fluorene-containing donor-polymers in organic photovoltaic devices

Abstract

Fluorene-containing PCBM analogs have been synthesized and tested with a polyfluorene copolymer, PF10TBT, in organic photovoltaic devices resulting in an increase of ∼130 mV in the open circuit voltage compared to devices with PCBM as acceptor material.
