Researchers from the State Key Laboratory of Luminescent Materials and Devices of the South China University of Technology, the University of Akron, and the Bruker Group's nanosurface laboratory recently announced the latest advances in the field of polymer solar cells by using conjugated polyelectrolytes PBDT-DTNT and The fullerene derivative electron acceptor PC71BM, the team produced an inverted structure (or inverted structure) organic solar cell with 8.4% conversion efficiency. The results have been published in the journal of the Royal Society of Chemistry. Due to the use of ITO/PEDOT:PSS/BHJ/Ba(Al) structures in traditional bulk heterojunction polymer solar cells, acidic sulfonated polyphenyl (PSS)-doped polythiophene derivatives (PEDOT) corrode ITO Effect, and the diffusion of indium ions will affect device performance. Dr. Yang Tingbin from South China University of Technology, Prof. Huang Fei from South China University of Technology's School of Materials, and Assistant Professor Gong Xiong from Akron University have worked together to eliminate the existing PEDOT:PSS layer by using an inverted structure. Improve battery stability. The researchers used ITO/ZnO/PFN-Br/PBDT-DTNT: PC71BM/MoO2/Ag structures to make the cell open circuit voltage 0.75V, short circuit current 17.4mA/cm2, fill factor 61%, and conversion efficiency 8.4%. The State Key Laboratory of Luminescent Materials and Devices was formally established in South China University of Technology in 2011. The laboratory mainly deals with key and important basic scientific issues of photoelectric functional materials and devices, and conducts basic physics problems based on luminescence and photoelectric conversion, and new molecular structure designs. Synthetic, high performance and practicality of materials, controllability of aggregated structure, high performance and integration of applied basic research, and strive to make new breakthroughs in the theory of luminescence and photoelectric conversion, and promote photovoltaics including solar cells The development of materials and other industries.
