Ternary bulk heterojunction organic photovoltaic cell

In this paper, a ternary bulk heterojunction organic photovoltaic cell was designed to improve the device performance. The performance of the device containing Poly(phenyleneethynylene), single walled carbon nantube, and (N,N'-diphenyl-N,N'-di-(m-tolyl)-p-benzidine is much better than a control BHJ device compring Poly(phenyleneethynylene) and single walled carbon nantube. We propose that the retard of the charge recombination may be a key factor in the device performance improvement.
