Interface recombination at the absorber buffer interface impedes efficiency of a solar cell with an otherwise excellent absorber. The internal voltage or quasi-Fermi level splitting (qFLs) measures quality reduces open circuit (VOC) respect to qFLs. present work explores facile sulfur-based post-deposition treatment (S-PDT) passivate CuInS2 thin films grown under Cu-rich conditions, which show ...

in this investigation, cuins2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. the cucl, incl3 along with (sc (nh2)2) were used as a precursor dissolved in high boiling point solvent such as oleylamine (ch(ch2)17nh2) and oleic acid (ch(ch2)16cooh) as a coordination solvent and capping agent, respectively. the size, distribution and shape were...
