Abstract
Single crystal anatase TiO2 nanospindles (NSs) with highly exposed {101} facets were synthesized and employed as electron transport materials (ETMs) in perovskite solar cells (PSCs). Time-resolved photoluminescence (TRPL) spectra revealed that the TiO2 NSs are more effective than TiO2 nanoparticles in accepting electrons from perovskite. Moreover, the TiO2 nanospindles further endowed the PSCs with good reproducibility and suppressed hysteresis. The best device with TiO2 NSs as ETMs yielded power conversion efficiency (PCE) of 19.6%, demonstrating that the home-made TiO2 NSs is a good ETM for PSCs.
