Thin film Cu(In,Ga)(S,Se)2-based (generally referred to as CIGS) solar cells represent a promising alternative to conventional crystalline silicon solar cells due to their high efficiencies, reduced cost, and better material utilization. In recent years, it has been demonstrated that it is possible to form thin films by annealing nanoparticulate material such that the nanoparticles coalesce to form...
This paper investigates the effect of using different selenization sources, namely elemental Se and H2Se, on Cu(In1−xGax)(SeyS1−y)2 devices derived from depositions of nanoparticle inks. Nanoparticles used in this synthesis are chalcogenides (e.g. CuInGaS). The effect of the selenization species has a large effect on the performance and electrical properties of these devices. Elemental selenized devices...
