Solution-processed inorganic solar cell based on in situ synthesis and film deposition of CuInS2 nanocrystals.
A novel, reproducible, and simple solution-based process for the fabrication of CuInS(2) absorber layers and CdS buffer layers for photovoltaics is presented. In this process, a precursor solution is deposited on a substrate, after which sintered NCs are formed in situ at temperatures as low as 250 degrees C. Solar cell efficiencies of up to 4% have been demonstrated using this novel fabrication method.
