The electronic device research team at Tsinghua University has recently enhanced the performance and stability of perovskite solar cells (PSCs) by incorporating a polymer additive during the crystallization process. This innovative approach has significantly improved the efficiency of these solar cells, achieving a remarkable conversion efficiency of 26.03%, surpassing the previous record of 25.51%.
The research, published on April 22, 2023, in the journal Energy & Environmental Science, highlights how the addition of the polymer enhances the structural integrity and interface stability of PSCs. The team utilized a polymer additive to regulate the crystallization process, leading to improved light absorption and reduced defects at the interface.
In their experiments, the Tsinghua team found that PSCs treated with the polymer maintained a high initial efficiency of 96.3% after 2000 hours of testing under continuous high-intensity light. This stability is particularly noteworthy, as it positions the polymer-enhanced cells as promising candidates for future solar energy applications.
Additionally, under conditions of high temperature and humidity (85°C with 50%-80% relative humidity), the polymer-treated PSCs displayed exceptional stability, emphasizing their potential for real-world applications where environmental conditions can be challenging.
The findings from this research not only establish a new benchmark for efficiency in perovskite solar cells but also pave the way for further advancements in the field of solar energy technology. The success of this approach demonstrates the critical role of material science in enhancing renewable energy solutions.
