Copper phthalocyanine-3,4',4,4' tetra-sulfonated acid tetrasodium salt (TS-CuPc) are promising interfacial materials for organic photovoltaics (OPVs) because of their electrical properties, solution process ability and stability. In this article, we report the fabrication of poly(3-hexylthiophene):[6,6]-phenyl-C61 butyric acid methyl ester (P3HT:PCBM) OPV devices incorporating solution-based TS-CuPc as electron transport layers that show promising enhancements of the device photocurrent and stability. We also discuss the impact of the mechanism of Photochemical and photophysical behavior and all parameters on device performance as well as the ambient degradation of these devices. In these results we showed charge extraction improvement by the use of the TS-CuPc. (C) 2016 Elsevier B.V. All rights reserved.
