Multifunctional Engineering-Enabled Electron Transport in SnO2 for Sn-Based Perovskite Solar Cells in the n-i-p Configuration
{{output}}
The two-step sequential deposition technique reported in the inverted p-i-n configuration to fabricate Sn perovskite solar cells fails in the TiO2-based n-i-p configuration since the latter aggravates Sn2+ oxidation from the SnI2 nucleation layer upon pore inf... ...
