Abstract Cu(In,Ga)S2–based solar cells have been shown by Hiroi et al (Hiroi 2015 IEEE Journal of Photovoltaics 6 309–312) to achieve higher efficiencies with absorbers processed at high deposition temperatures. Additionally, it is known for CuInS 2 that the main improvement from temperatures reduction in density deep defects and increased quasi-Fermi level splitting. The splitting could result...
