Iron pyrite (FeS 2 ) is a naturally abundant and nontoxic semiconductor that can potentially be used in photovoltaic devices. In this report, pure pyrite FeS 2 thin films with homogeneous morphology and ideal composition are fabricated by sulfurizing Fe 2 O 3 precursor thin films deposited via successive ionic layer adsorption and reaction method. The formation mechanism...
CuGaSe 2 thin films have been prepared by one-step electrodeposition and rapid thermal annealing process. According to composition and morphology analysis, deposition potential of −0.6V vs. SCE is considered to be optimum for electrodeposition. From the X-ray diffraction and Raman studies, the as-deposited film exhibits poor crystallinity without the evidence of CuGaSe 2 or other Ga-containing...
