Novel Semiconducting Polymers for Highly Efficient Solar Energy Harvesting

Abstract

In the past three years, our research project sponsored partially by AFOSR has been focused on developing low bandgap semiconducting polymers as the donor components for BHJ solar cells. We have made very important contributions to the field and has developed a series of new semiconducting polymers with thieno[3,4-b]thiophene and benzodithiophene alternating units. They exhibited superior solar energy PCE to polymers disclosed in literature in BHJ polymer solar cells in combination with fullerene derivatives as acceptors. Solar power conversion efficiency has reached to 9.4 . In addition to those achievements, we have gained deeper insight in understanding design principles for these high efficiency polymers. In the elucidation of structure/property relationship, we uncovered the local dipolar effect for designing highly efficient semiconducting polymers for OPV solar cells, which gives us solid design principle to search better materials.
