Lead iodide perovskite solar cells have emerged as a transformative technology in the field of photovoltaics, demonstrating remarkable power conversion efficiencies that rival traditional silicon- based solar cells. However, conacerns regarding their long-term stability and environmental impact pose significant challenges for their widespread adoption. This study investigates the current advancements in lead iodide perovskite solar cells, emphasizing strategies to enhance both their efficiency and stability. We explore innovative approaches, such as compositional engineering, interface modification, and encapsulation techniques that mitigate degradation mechanisms and extend operational lifetimes. Furthermore, the environmental implications of lead use in these solar cells are critically examined, proposing potential alternatives and recycling strategies to minimize ecological footprints. Our findings contribute to the ongoing discourse on sustainable energy solutions, highlighting the promise of lead iodide perovskite solar cells while addressing the crucial issues of stability and environmental safety. Scientists have been searching for a non-conventional, easily accessible, and sustainable energy source that primarily uses solar cells for a long time. Solar cells are a low-cost, carbon-emission-free energy source that converts light energy, or photons, directly into electrical current, or electrical energy, by utilizing the photovoltaic phenomenon. Perovskites, especially organic-inorganic halide perovskites, have become more and more popular recently because of their exceptional optical properties and low processing temperature requirements. The first developed perovskite solar cell was introduced in 2009 when CH3NH3PbI3 organometallic perovskite with a liquid-based hole transport layer was added to a dye-sensitized solar cell.
