Sources: 3. Developments: 2. Researchers at Nanjing University have made advancements in perovskite solar technology aimed at improving efficiency and stability for industrial-scale production. Initial developments focused on creating a super-stable, ultra-thin protective coating to prevent material degradation from moisture and oxygen. This coating allows for the development of tandem modules that layer perovskite onto traditional silicon to capture a wider light spectrum. Subsequent research achieved a record efficiency of 27.35% using a perovskite-organic tandem solar cell. This was accomplished through a new low-bandgap acceptor designed to enhance near-infrared light capture and improve photocurrent matching. The device demonstrated stability by maintaining 80% of its initial performance after 744 hours of continuous illumination. ## Timeline ### 2026-09-13: Nanjing University researchers achieve 27.35% efficiency in tandem solar cells Nanjing University researchers achieved a 27.35% efficiency record for perovskite-organic tandem solar cells using a new low-bandgap acceptor to improve near-infrared light absorption. 3 sources. https://clstr.news/cluster/nanjing-university-researchers-achieve-2735-efficiency-in-tandem-solar-cells ### 2026-08-15: Nanjing University researchers develop high-efficiency perovskite solar technology A China-Canada research team led by Nanjing University has developed a stable perovskite coating, paving the way for low-cost, high-efficiency solar panels to be produced at an industrial scale. 2 sources. https://clstr.news/cluster/nanjing-university-researchers-develop-high-efficiency-perovskite-solar-technology --- Cite as: Nanjing University perovskite solar technology development.
