Abstract

We demonstrate hybrid photovoltaic (PV) cells based on n-i-p heterojunctions with incorporated zinc oxide (ZnO) films using a sol-gel method. The cells, employing stibnite (Sb 2S 3), and poly(3-hexylthiophene) (P3HT) materials, as light absorption layers, constitute an active region in the indium tin oxide (ITO)/ZnO(n)/Sb 2S 3(i)/P3HT(p)/Ag hybrid structure. Our investigation shows that annealing temperature has a significant effect on both the crystallinity and optical absorption of Sb 2S 3 films. The near-intrinsic Sb 2S 3 films annealed at 300°C exhibits dark conductivity of 1.42×10 -7Scm -1. The performance of PV cells strongly depends on thermal treatment of Sb 2S 3, and on the thickness of both the Sb 2S 3 and P3HT layers. Electronic structures of annealed Sb 2S 3 films was further studied by photoelectron spectroscopy to understand the physics behind. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
