Interface Engineering of Wide-Bandgap Perovskite Solar Cells
Wide-bandgap (WBG) perovskite solar cells (PSCs), essential sub-cells in tandem solar cells (TSCs), play a key role in determining overall device performance. Achieving the desired bandgap typically involves incorporating bromide alongside iodide, enabling WBG PSCs to exhibit high efficiency and stability. Nevertheless, their performance is often limited by surface defects caused by incomplete material coordination. These defects hinder carrier transport, reduce the open-circuit voltage (Voc), promote non-radiative recombination, and induce phase segregation, compromising device stability. This study aims to enhance the stability and quality of FA0.75Cs0.25Pb(I0.5Br0.5)3 perovskite surfaces using PDABr (propane-1,3-diammonium bromide) as a passivation layer. This approach is intended to mitigate surface defects, promote uniform crystallization, and improve both the stability and performance of the resulting solar cell devices.
