Article Synopsis
- - Wide bandgap perovskite solar cells have high voltage output but struggle with issues like deep valence bands and phase segregation.
- - Two different alkylthiophene-substituted polythiophenes, PT4T-0F and PT4T-2F, are tested as interfacial layers, with PT4T-2F showing better properties such as higher hole mobility and improved crystal growth in the solar cells.
- - The optimized solar cell using PT4T-2F achieves an open-circuit voltage of 1.23 V and a power conversion efficiency of 19.20%, along with enhanced stability against moisture and heat, suggesting a promising direction for future solar cell engineering.
