TLDR
In this article, spray pyrolised CuSbS2 thin films were synthesized and characterized using X-ray diffraction, Raman spectroscopy, Xray photoelectron spectrography, atomic force microscopy, UV-visible spectrograms, and Hall effect measurements.Abstract:
Copper antimony sulfide (CuSbS2) thin films have been gained interest recently as an emerging light absorbing material for photovoltaic applications. In this work we report synthesis and characterization of spray pyrolised CuSbS2 thin films. The precursor solution consisted of SbCl3, CuCl2 and NH2CSNH2 dissolved ethanol. The substrate temperature was kept at 200 °C. Samples were prepared at different molar ratios of Cu:Sb:S. These thin films were characterized using X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, atomic force microscopy, UV-visible spectroscopy, photocurrent and Hall effect measurements. P-type CuSbS2 thin films of orthorhombic structure were formed and the films showed photocurrent response. (© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)read more

TL;DR: The resulting conduction band misalignment with CdS is a reason for the poor performance of cells incorporating a CAS/CdS heterojunction, supporting the idea that using a cell design analogous to CIGS is unhelpful.
