Continuous breakthroughs have been achieved in the photoelectric conversion efficiency (PCE) of tin-based perovskite solar cells (TPSCs) recent years. Inspired by performance improvements observed during device storage, we identified beneficial light-induced interface doping (LIID) TPSCs. In situ analyses using X-ray photoelectron spectroscopy and ultraviolet reveal that ion migration oxidation at induce effects, enhancing carrier transport significantly boosting performance. By implementing specific illumination techniques or maximum power point tracking (MPPT) methods to achieve LIID, increased open-circuit voltage while maintaining a high short-circuit current, reaching PCE up 14.91%. Furthermore, this was sustained 70% its value after nearly 900 h continuous operation. Our study introduces novel approach addressing energy band mismatch, paving way for improved cells.

Moreover, solution-processable facile technologies offer low-cost, low-temperature, scalable fabrication these cells. Numerous studies focused on improving the performance, stability, and processing PSCs. However, potential lead toxicity poor long-term stability impede commercialization. In recent years, several developed novel encapsulants for PSCs that can simultaneously improve leakage. Although improvements been made both fronts, no solution date could achieve level leakage prevention result in market breakthrough. Here, we analyze PSC encapsulation techniques undertaken years.
