Abstract

The size effect of the TiO₂ photoanode has been investigated on the hole-conductor-free fully printable mesoscopic perovskite solar cells based on the carbon counter electrode and (5-AVA)_x(MA)_1−xPbI₃ perovskite. With TiO₂ nanoparticles with an optimized diameter of 25 nm, a champion device exhibits an efficiency of 13.41%.
