Abstract

Clean, benign and economical energy harvesting is envisioned to mitigate the global climate change – originated from the burning of fossil fuels – addressing both the energy crises and environmental issues. In this work, charge transport mechanism and the dynamics of photocurrent generation in thin films of CZTS nanocrystals is studied. A liquid phase processing route – owing to low temperature – has been adopted using a molecular based precursor solution for the in-situ development of CZTS crystals during film deposition. Results shows that charge carriers follow band conduction and nearest-neighbor hopping (NNH) mechanisms at elevated temperatures while Mott variable-range hopping (VRH) is the dominating phenomenon at low temperatures which are analogues to expensive vacuum-deposited kieserite thin films behavior.
