Paper Abstract

In order to upscale the production of thin film solar cells a cost effective and simple synthesis technique is required. Keeping this in mind we have investigated the effect of electrochemical deposition (ED) and inherently low thermal budget rapid thermal annealing (RTA) processing of CuInSe2 in sulfur atmosphere. X-ray diffraction (θ-2θ) scans indicate increased grain size and improved crystallinity after RTA of ED films. Scanning electron microscopy images (SEM) suggest changes in surface morphology after sulfur incorporation. Raman spectroscopy results and temperature dependent conductivity measurements are also discussed in the paper.
