Composition dependence of electronic defects in CuGaS2
Damilola Adeleye, Mohit Sood, Michele Melchiorre +2
CuGaS2 films grown by physical vapour deposition have been studied by photoluminescence (PL) spectroscopy, using excitation intensity and temperature dependent analyses. We observe…

CuIn(Se,Te)2 absorbers with bandgaps < 1 eV for bottom cells in tandem applications
Thomas Paul Weiss, Mohit Sood, Aline Vanderhaegen +1
Thin-film solar cells reach high efficiencies and have a low carbon footprint in production. Tandem solar cells have the potential to significantly increase the efficiency of this…

Electrical barriers and their elimination by tuning (Zn,Mg)O composition in Cu(In,Ga)S2: Systematic approach to achieve over 14% power conversion efficiency
Mohit Sood, Poorani Gnanasambandan, Damilola Adeleye +4
Traditional CdS buffer layer in selenium-free Cu(In,Ga)S2 solar cells leads to reduced open-circuit voltage because of a negative conduction band offset at the Cu(In,Ga)S2/CdS inte…
