- •
High performance planar perovskite solar cell is prepared based on the compact TiO2 films grown by RF sputtering.
- •
A high open circuit voltage of about 1.03 V can be obtained as compared to 0.92 V of solution based TiO2.
- •
Nearly 100% coverage of perovskite film on sputtered TiO2 can be observed using the one step method.
- •
The full coverage and the proper band alignment are two reasons responsible for the high open circuit voltage.
