PC is really a complex field since it involves several basic processes such as generation, recombination and transport of charge carriers. In order to understand these, one requires knowledge of other parameters that are not easy to control as these vary tremendously with the material, temperature, doping level, presence of donors, acceptors and traps, their concentration, capture cross-section, mobility of the charge carriers, type of electrical contacts, potential barriers created near them and unintentionally introduced defect states in the growth process. In this work I have provided the results of the photoconductivity studies I have undertaken on the In2S3 thin films using different techniques. The conclusions seems to explain the fundamentals of the transport phenomena observed in this system and provides a general approach for the evaluation of electrical transport in other polycrystalline thin film semiconductor composites that outperform their crystalline counterparts.
