Perovskite solar cells (PSCs) are acclaimed as remarkable devices for converting light into electricity. The crystallinity of the perovskite layer defines its performance, efficiency, and stability. Defects/trap states may negatively affect photovoltaic device performance. Using additives can enhance power conversion efficiency (PCE) durability PSCs. additive approach reduces defects at film surface grain boundaries. In this study, we introduce 1,2,4-triazole (TZL) a precursor solution to improve quality film, larger crystal grains, crystalline structures, PCE, longevity carbon-based presence three nitrogen atoms in TZL strengthens hydrogen bonding structure, enhancing material efficiently defects/traps, potentially charge carrier transportation, minimizes nonradiative recombination resulting enhanced durability, performance Carbon-based PSCs with 5 mg added had an improved PCE 10.66% when compared control MAPbI3 (8.32%). Furthermore, greatly improves long-term stability (under condition 30 °C RH = 50% ± 5%) CPSCs, allowing them retain 85% their initial after 500 h preservation. Our results demonstrate that quality, CPSC durability.
