초록
CuInSe2 thin films which have been widely used for thin solar cells as a light absorber were prepared by hydrazine solution processing, and their microstructural properties were investigated. Hydrazine CuInSe2 precursor solutions were prepared by dissolving Cu2S, S, In2Se3 and Se powder in hydrazine solvent. Multilayer CuInSe2 chalcopyrite phase thin films were prepared by repeating spin-coating process using the precursor solution. Unfortunately, the presence of the interfaces between each CuInSe2 layer formed by multi-layer coating impeded grain growth across the interface. Here, by doing simple interface engineering to solve the limited grain growth issue, the large grained (~1 μm) CuInSe2 thin films were obtained.
