Performance Enhancement of All-Inorganic Carbon-Based CsPbIBr<sub>2</sub> Perovskite Solar Cells Using a Moth-Eye Anti-Reflector
All-inorganic carbon-based CsPbIBr<sub>2</sub> perovskite solar cells (PSCs) have attracted increasing interest due to the low cost and the balance between bandgap and stability. However, the relatively narrow light absorption range (300 to 600 nm) limited the further improvement of shor...

| description | All-inorganic carbon-based CsPbIBr<sub>2</sub> perovskite solar cells (PSCs) have attracted increasing interest due to the low cost and the balance between bandgap and stability. However, the relatively narrow light absorption range (300 to 600 nm) limited the further improvement of short-circuit current density (J<sub>SC</sub>) and power conversion efficiency (PCE) of PSCs. Considering the inevitable reflectance loss (~10%) at air/glass interface, we prepared the moth-eye anti-reflector by ultraviolet nanoimprint technology and achieved an average reflectance as low as 5.15%. By attaching the anti-reflector on the glass side of PSCs, the J<sub>SC</sub> was promoted by 9.4% from 10.89 mA/cm<sup>2</sup> to 11.91 mA/cm<sup>2</sup>, which is the highest among PSCs with a structure of glass/FTO/c-TiO<sub>2</sub>/CsPbIBr<sub>2</sub>/Carbon, and the PCE was enhanced by 9.9% from 9.17% to 10.08%. The results demonstrated that the larger J<sub>SC</sub> induced by the optical reflectance modulation of moth-eye anti-reflector was responsible for the improved PCE. Simultaneously, this moth-eye anti-reflector can withstand a high temperature up to 200 °C, and perform efficiently at a wide range of incident angles from 40° to 90° and under various light intensities. This work is helpful to further improve the performance of CsPbIBr<sub>2</sub> PSCs by optical modulation and boost the possible application of wide-range-wavelength anti-reflector in single and multi-junction solar cells. |
