Mesoscopic cell structure and fluorine-doped tin oxide (FTO) glass have been the architect and substrate of choice, respectively, for state-of-the-art perovskite solar cells (PSCs). Although ITO is optical superior to FTO, the high-temperature annealing required for the fabrication of TiO 2 layers causes conductivity loss in the ITO.
Printable mesoscopic perovskite solar cells (PSCs) have received extensive attention due to their convenient large-area fabrication and good stability. The further improvement of the power conversion efficiency (PCE) of such simplified PSC configuration is limited by the low open circuit voltage ( V OC ).
