Influence of the Electron Selective Contact on the Interfacial Recombination in Fresh and Aged Perovskite Solar Cells
In this work, we have used TiO<sub>2</sub> and SnO<sub>2</sub> layers as electron selective contact (ESC) in n-i-p perovskite solar cells configuration. To study and compare the ion migration kinetics of these ESC, CsFAMAPbIBr and MAPbI<sub>3</sub>-based devices w...

| description | In this work, we have used TiO<sub>2</sub> and SnO<sub>2</sub> layers as electron selective contact (ESC) in n-i-p perovskite solar cells configuration. To study and compare the ion migration kinetics of these ESC, CsFAMAPbIBr and MAPbI<sub>3</sub>-based devices were fabricated and characterised in fresh (1 day) and aged (28 days) conditions. Depending on the ESC and perovskite composition, devices reveal a different progression over time in terms of hysteresis and performance. Using transient photovoltage (TPV) and transient photocurrent (TPC) techniques, we studied the kinetics of carrier extraction and recombination, which showed that aged devices present slower recombination kinetics compared to their fresh counterparts, revealing a positive effect of the aging process. Finally, transient of the transient, derived from the TPV technique, discloses that TiO<sub>2</sub> accumulates more charges in the ESC/perovskite interface compared to SnO<sub>2</sub> and that the ion migration kinetics are directly related to the perovskite composition. |
