Control of the constituent phase and stoichiometry of iron pyrite (FeS2) is a prerequisite for high-performance photovoltaic devices based on this material. If the pyrite contains sulfur-deficiency-related secondary phases which have a metallic chara

The structural and electro-optical influence of marcasite on the properties of solution-processed iron pyrite thin films was investigated. Marcasite has a strong tendency to form simultaneously with pyrite upon sulfurization of amorphous iron-oxide p

An amorphous Cu–In–S nanoparticle-based precursor ink with improved atom economy was developed in which a large amount of bulky organic ligands was replaced with metal salt–organic ligand complexes. This change resulted in a reduction of the re

In this study, we characterized FeS2 thin films grown by the non-vacuum spin-coating method. We annealed the samples under a sulfur atmosphere at different sulfurization temperatures. The phase transformation from marcasite-containing pyrite to pure

One of the most important experimental factors in selenization, in which a precursor material is annealed at high temperature with Se vapor or gas to form chalcogenide light-absorbing layers, is the partial pressure of the Se vapor or gas (PSe). Alth

We report a new approach for fabricating pyrite (cubic FeS2) thin films via a non-vacuum direct solution coating route using iron-acetate dissolved in ethanol as a precursor solution. The precursor ink is deposited by spin coating and annealed in air

We report an efficiency limiting factor of CuInGaSe2 (CIGS) thin film solar cells fabricated by rapid thermal annealing (RTA) of sputter-deposited Cu-In-Ga-Se films without an additional supply of Se vapor. The CIGS thin films show a single-phase cha
