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 conventional 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, Professor Huang Fei from South China University of Technology's School of Materials, and Assistant Professor Gong Xiong from Akron University have worked together to remove the original PEDOT:PSS layer by adopting 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 achieve new breakthroughs in the theory of luminescence and photoelectric conversion, promote photovoltaics including solar cells The development of materials and other industries.
We can manufacture various shape and special material optical lens.The coating for lenses not only the normal BBAR coating,but also including dichroic coating and super broad band antireflective coating.
Plano-Convex (PCX) Lenses have a positive focal length, making them ideal for collecting and focusing light in imaging applications. They are also useful in a variety of applications involving emitters, detectors, lasers, and fiber optics. Coated versions have optimum light transmission. Available in a wide variety of diameters and focal lengths.
The uncoated lenses are ideal for a multitude of optics and photonics applications, as well as biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.
The coated lenses can be utilized in a host of optics and photonics applications, including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.
