Abstract
- The uniform and compact n-type TiO 2 window layers were prepared by RF sputtering using a TiO 2 ceramic target. A high open circuit voltage of about 1.03 V with the efficiency of 13.23% can be obtained as compared to 0.92 V of solution based TiO 2 . Nearly 100% coverage of perovskite film on sputtered TiO 2 can be observed in the scanning electron microscopy images, obviously higher than 92% coverage on solution-based TiO 2 . The full coverage of perovskite and the proper band alignment between sputtered TiO 2 and spiro-OMeTAD are two reasons responsible for the high open circuit voltage. The effects of annealing, growth temperature, sputtering target and thickness on performance of solar cell are also discussed.
