- Abstract
- A uniform compact layer is essential for obtaining high-efficiency perovskite solar cells (PSCs). This is because direct contact between the FTO glass substrate and the perovskite layer should be blocked to suppress electron recombination and to collect electrons. In the present study, PSCs were fabricated using sputtered TiO2 compact layers prepared at different deposition times. The structure, morphology, and electrical properties of the sputter deposited TiO2 compact layer were compared to those of a spin coated TiO2 film. The TiO2 compact layer prepared by the sputtering process was very smooth and inhibited electron recombination at the FTO interface, resulting in a higher open circuit voltage and a higher short circuit current density. A photoelectric conversion efficiency of 13.37% was obtained using the TiO2 compact layer deposited for 30 min.
