我国科研团队攻克大尺寸钙钛矿光伏电池量产难题

Core Viewpoint - A joint team from Nanjing University and Renshuo Energy has developed an environmentally friendly solvent for large-scale production of perovskite solar cells, addressing key challenges in stability, environmental impact, and reliability [1][2]. Group 1: Research and Development - The new solvent allows direct contact with air and has been shown to improve the crystallization process of perovskite materials, overcoming previous issues with adhesion and stability [1]. - The team introduced a "solvent edge protection" strategy, which involves adding an additive to slow down the evaporation rate at the edges of the solution, enhancing the quality of the perovskite film [1]. Group 2: Commercialization and Testing - The team has successfully produced commercial-sized components measuring 1.2 meters by 0.6 meters, which have passed various reliability tests including humidity, thermal cycling, and UV exposure [2]. - The components have received certifications from testing institutions in Germany, the United States, and China, demonstrating stable photoelectric conversion efficiency in outdoor tests conducted in Suzhou [2]. Group 3: Future Plans - Nanjing University and Renshuo Energy have filed a patent application for the new technology and have established a 150 MW pilot production line to produce stable finished products [2]. - The team plans to continue enhancing the efficiency and stability of perovskite solar cells while pushing for market entry [2].
