High-Performance, Fullerene-Free Organic Photodiodes Based on a Solution-Processable Indigo

Adv Mater. 2015 Nov 4;27(41):6390-5. doi: 10.1002/adma.201502936. Epub 2015 Sep 22.

Abstract

A solution-processable dibromoindigo with an alkyoxyphenyl solubilizing group is developed and used as a new electron acceptor in organic photodiodes. The solution-processed fullerene-free organic photodiodes show an almost spectrally flat response with a high responsivity (0.4 A W(-1)) and a high detectivity (1 × 10(12) Jones). These values are comparable to silicon-based photodiodes.

Keywords: electron acceptors; indigo; nonfullerenes; organic photodiodes; solution-processable acceptors.
