The Institute of Applied Physics and Materials Engineering (IAPME) at the University of Macau (UM) was delighted to host Prof. Guojia Fang from Wuhan Textile University for a research seminar on 14 May 2026. The event was part of the celebration activities marking the 45th anniversary of UM.
Prof. Fang, a Distinguished Professor and leader of the Advanced Energy and Future Display Technology Center at Wuhan Textile University, delivered a talk titled “light Management and Interface Regulation in Perovskite Solar Cells.” In his presentation, he introduced a universal strategy using highly distributed fluorine-doped tin oxide nanoplates (NP-FTO) on glass substrates, combined with an electron-selective homojunction formed by ALD-SnO₂ and SnO₂ quantum dots. This approach significantly improves omnidirectional photon harvesting and perovskite crystallization.
Prof. Fang reported that the best-performing n-i-p perovskite solar cell achieved a remarkable power conversion efficiency (PCE) of 26.4% (certified 25.9%) under AM 1.5G illumination, retaining 95% of its initial efficiency after 1,200 hours of maximum power point tracking. He also demonstrated that the NP-FTO strategy is applicable to 1.77 eV wide-bandgap p-i-n perovskite cells, enabling all-perovskite tandem solar cells with a champion PCE of 28.2%.
The seminar attracted more than 30 faculty members, postdoctoral fellows, and students from IAPME and other departments. A lively and in-depth discussion followed the talk, covering charge transport layer design, interface engineering, and tandem device fabrication. The exchange has opened new avenues for collaborative research between UM and Wuhan Textile University in the field of high-performance perovskite optoelectronics.
