Loading of mesoporous titania films by CH3NH3PbI3 perovskite, single step vs. sequential deposition†
Abstract
Infiltration of mesoporous TiO2 scaffolds by CH3NH3PbI3 is more complete when using sequential compared to single step deposition processing and avoids formation of disordered capping layers affording greatly improved performance of perovskite based photovoltaics.
