Paper Abstract

A new low band gap polymer (pBEHTB) with an absorption onset at 800 nm is reported. When combined with a soluble fullerene derivative (PCBM), efficient electron transfer occurs after excitation of the polymer. Bulk heterojunction solar cells have been prepared with a response up to 800 nm, and an estimated power conversion efficiency of 0.9 %.
