초록

The properties of the electron transport layer (ETL) have a great effect on perovskite solar cell performance. Depositing conformal SnO2 ETL on bottom textured silicon cells is essential to increase current density in terms of the silicon-perovskite tandem solar cells. In the recent study, the SnO2 electron transport layer deposited by the sputtering method showed an efficiency of 19.8%. Also, an electron transport layer with a sputtered TiO2 electron transport layer in a 4-terminal tandem solar cell has been reported. In this study, we synthesized SnOx ETL with a various sputtering power range of 30-60W by Radio-frequency (RF)-magnetron sputtering. The properties of SnOx thin film were characterized using ellipsometer, UV-vis spectrometer, and IV measurement. With a sputtering power of 50W, the solar cell showed the highest efficiency of 13.3%, because of the highest fill factor by the conductivity of SnOx film.
