Chengdu Organic Chemistry Co., Ltd., Chinese Academy of Sciences of the State to bear the “863″ issue – polymer lithium-ion battery(367759-001, hstnn-ib09) separator projects, through the identification of the Sichuan Provincial Science and Technology Agency.

The project uses polymer grafting reaction route, using the principle of separation of cyano group Preparation of nano-porous polymer electrolyte membrane technology is the first at home and abroad, prepared by the use of cast polymer membrane electrolysis system, preparation is simple, low production cost, with good market competitiveness and significant economic and social benefits. Polymer membrane electrolysis system with the preparation of polymer lithium-ion battery(hp pavilion dv1000 battery, hp pavilion dv4000 battery) has a good charge-discharge performance.

Light by the State Quality Supervision and Test Center battery tests, polymer batteries to achieve the national standard. In polymer supercapacitors show good prospects for development.

Copper indium-selenium thin film solar cell technology research to make a breakthrough

Recently, optoelectronic thin film devices by Nankai University and Professor Sun Yun Institute of Technology Task Force to assume the state “15 863″ major feature “thin-film copper indium selenium solar cells in the test platform and experimental line” made a crucial breakthrough in the sun as a symbol the overall level of the battery indicator – battery photoelectric conversion efficiency of 12.1%.

Copper indium-selenium thin film solar cell (referred to as copper indium selenium cell – gd761, kd476, td347, dell inspiron 1501 battery, dell inspiron 6400 battery) is a substrate of glass or other cheap metal layer deposited on a number of compound semiconductor thin film, thin-film total thickness of about 2-3 microns, the use of solar power generation. Copper indium selenium cell with a low-cost, stable performance, strong anti-radiation properties, photoelectric conversion efficiency is the first in a variety of thin-film solar cells, it is precisely because of its excellent performance by the international community as the next era of cheap solar energy batteries, attracted a large number of institutions and experts to conduct research and development. However, copper indium selenium cell is a multi-compound semiconductor devices, with complex and sensitive multi-storey structure ratio of the elements, processes and preparation of its extremely harsh conditions, only the United States, Japan, Germany completed the development of pilot-line, but large-scale production has not yet been achieved.

At the national “Tenth Five-Year 863″ Project of Tianjin Science and Technology, Nankai University, co-funded research group at all levels through the formation mechanism of thin film materials and reaction kinetics, the device structure and interfacial interactions at all levels on key issues such as, made significant progress, some have made breakthroughs in key technologies and applications for two patents. At the same time, the battery makes copper indium selenium photoelectric conversion efficiency in a more stable basis of 8-10% reached 12.1%, 3.5 × 3.6cm integrated battery conversion efficiency of 6.6, the completion of the Ministry of Science and Technology and Tianjin Science and Technology Commission issued the first stage of the study task, in order to follow the development has laid a solid foundation.

Copper indium selenium cell is the most promising next-generation thin film solar cells, one may become the future of solar cell commercialization and industrialization of the mainstream products. At present, the group is stepping up efforts to test lines of research and development, and strive to achieve in the next 5 years technical leap, open the “basic research – the development of laboratory techniques – in the test technology development – the realization of industrialization” of the channel .
