Advancements in Perovskite Solar Cell Efficiency and Stability

Recent advancements in perovskite solar cells (PSCs) have focused on improving efficiency, stability, and recycling processes. The Hong Kong University of Science and Technology has enhanced PSC efficiency to nearly 26% by addressing cation distribution issues in perovskite films, offering potential cost reductions and broader application. A green solvent-based recycling strategy for PSCs has been developed, addressing environmental impacts associated with lead content. Bifacial PSC designs with anti-reflective coatings are being explored to improve light capture and durability. Long-term stability remains a challenge, with thermal stress identified as a significant factor in material degradation. Bromide-based perovskites show promise for improved stability over iodide-based counterparts, potentially increasing the efficiency and longevity of PSCs.
