摘要

Organic–inorganic halide perovskite solar cells (PSCs) have become increasingly competitive with traditional photovoltaic technologies, reaching efficiencies of ~ 27% by 2025. However, their long-term stability remains a major challenge. Incorporating carbon-based materials into PSCs offers promising strategy to slow down degradation processes and enhance device longevity. This study investigates the impact of detonation nanodiamonds (DNDs), doped with boron, phosphorus, and silver, on the photovoltaic performance, structural characteristics, and long-term stability of organic–inorganic perovskite films. Characterization techniques including AFM, FTIR and current–voltage (I–V) measurements were employed. The results show that doping perovskite films with these modified DNDs enhances the electrical stability of the composites without compromising their photoresponse. This approach presents a viable pathway toward the development of high-efficiency, long-lasting perovskite solar cells and related optoelectronic devices.
