Abstract: 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 show higher efficiencies (>16%) compared to H2Se processed devices (<12%). Various techniques are used in this study, including Raman spectroscopy, TEM, I-V-T, EQE, admittance spectroscopy and C-V-T to identify the difference in performance between the two selenization methods. Differences are observed in both the bulk and interface properties of the devices.
