Efficient squaraine-based solution processable bulk-heterojunction solar cells

J Am Chem Soc. 2008 Dec 31;130(52):17640-1. doi: 10.1021/ja8067879.

Abstract

We report the fabrication of organic bulk-heterojunction solar cells based, for the first time, on squaraine/PCBM blends. The most efficient device, solution-processed in air, exhibits J(sc) = 5.70 mA/cm(2), V(oc) = 0.62 V, fill-factor = 0.35, and power conversion efficiency = 1.24%, one of the highest to date for a small molecule solution-processed bulk-heterojunction cell.
