| 제목 | Sb2Se3 thin films prepared by atomic layer deposition and their PV applications |
| 초록 | Recently simple binary and ternary semiconductors such as AgBiS2, CuSbS2, CuSbSe2, PbS, SnS, Sb2S3, and Sb2Se3 have attracted intensive attention as a low-cost and stable light absorbing materials. Among them, Sb2Se3 binary chalcogenide compound is considered to be a promising photovoltaic material due to their relatively low toxicity, long term stability, and earth abundant element availability. In this work, we have tried to deposit Sb2Se3 thin films by using ALD, which was proceeded by the reaction of tetrakis(dimethylamino)antimony (TDMASb) and diethylselenide (DESe) at low temperature (120 °C). Uniformly deposited ALD Sb2Se3 thin films were applied to the superstrate solar cells with the structure of ITO/CdS/ALD Sb2Se3/Au and we have investigated the possibility of ALD Sb2Se3 as a photovoltaic absorber. This work was supported by the DGIST R&D Programs of the Ministry of Science, ICT & Future Planning of Korea (18-BD-05). |
