What is Interfacial Modification to Improve All-inorganic Perovskite Solar Cells by a Multifunctional 4-Aminodiphenylamine Layer about?
All-inorganic carbon-based perovskite solar cells (PSCs) offer low costs and a favorable balance between stability and power conversion efficiency (PCE). Although bulk perovskites are defect tolerant, the defectmediated carrier nonradiative recombination at the interface between perovskite and carbon layers limits the device performance and stability. In this study, a new 4-aminodiphenylamine (4-ADPA) interlayer was applied to modify the surface and grain boundaries of CsPbI 2 Br perovskite films. The 4-ADPA layer passivated defects by binding with undercoordinated lead and halide ions at the surface, resulting in the improved thin film quality, reduced defects, and suppressed carrier recombination. All-inorganic CsPbI 2 Br PSCs by 4-ADPA passivation achieved a PCE of 11.16% with reduced hysteresis and open-circuit voltage loss. In addition, the 4-ADPA passivation inhibited the degradation of the perovskite films in ambient conditions. After storing in air at 25 °C and 25% relative humidity for 700 h, the unpackaged PSC retains 80% of the original PCE. The all-inorganic PSCs with greatly improved device performance and stability would have great prospects in practical applications.
