Scientists Develop New Method to Make Perovskite Solar Cells More Efficient and Durable

NEW YORK:A team of researchers co-led by scientists from the University of California, San Diego, has developed a new method to improve the efficiency and durability of perovskite solar cells, potentially advancing the development of low-cost solar energy technology.

According to the research findings, the scientists temporarily generated a liquid during the crystallisation process, enabling the formation of larger, more uniform perovskite crystals with fewer defects.

Perovskite is considered a promising material for next-generation solar cells because it can offer high efficiency while potentially reducing manufacturing costs.

Solar cells and light-emitting diodes (LEDs) made using the perovskite materials achieved efficiencies of approximately 24% to 26%, representing strong performance for perovskite-based devices.

The researchers also found that the solar cells retained most of their initial performance after operating continuously under simulated sunlight for eight weeks, indicating improved stability under laboratory testing conditions.

Unlike conventional silicon solar cells, perovskite materials can be processed from liquid solutions and deposited as thin films onto surfaces. This approach could simplify manufacturing processes and reduce the energy required for production.

The development could help address two major challenges facing perovskite technology: maintaining high efficiency and ensuring long-term durability.

Although further research and testing under real-world conditions will be needed, the findings offer promising prospects for developing more efficient, affordable and sustainable solar energy systems.
