Perovskite solar cells (PVSCs) are a promising choice to standard silicon-based solar cells because of their high power-conversion performance and low cost. Nevertheless, one of the significant challenges in their growth has actually been achieving long-lasting stability.

While the power conversion efficiency of perovskite solar cells (PVSCs) - a future of solar cells - has currently greatly enhanced in the past decade, the problems of instability and also potential ecological influence are yet to be gotten rid of. Lately, scientists from City University of Hong Kong (CityU) have developed a novel technique which can concurrently tackle the leakage of lead from PVSCs as well as the stability problem without compromising efficiency, paving the way for real-life application of perovskite photovoltaic or pv technology.
