다국어 초록 (Multilingual Abstract)

Sb₂Se₃ is a typical V₂-VI₄ binary chalcogenide with single phase and fixed composition and recently attracting many interests from many photovoltaic researchers because of its high absorption coefficient, low-cost. In the case of Sb₂Se₃ solar cells, interfacial engineering of a Sb₂Se₃ light absorber layer and other component layers such as a metal electrode and an electron transport layer is an important factor to enhance photovoltaic performance of Sb₂Se₃ solar cells. In this study, we have tried to apply a conformal amorphous ALD TiO₂ thin film as an interfacial protection layer for Sb₂Se₃ solar cells. Uniformly deposited amorphous ALD TiO₂ thin films were applied to the Sb₂Se₃ solar cells with the structure of Mo/Sb2Se3/ALD TiO₂/CdS/ZnO/AZO/Al and we have investigated the possibility of the ALD TiO₂ thin film as an absorber protection layer.
