Efficient heterojunction solar cells will be mass production

Reporter from the recently held in the national 863 project "efficient heterojunction solar cell projects" industrialization of conference, according to a kind of power generation efficiency increased by 30% than conventional monocrystalline silicon solar cells of new high efficiency solar cell to realize the mass production in our country.China renewable energy institute director feldspar on media said at the meeting, the photovoltaic industry has become a new vital force and energy market in our country the main producer of the global photovoltaic products.

Solar cells as a photovoltaic power station is a key ring, the development of technology and cost control has been praised by the industry.China can build deputy general manager, chief engineer hou-gui zhou said, effectively improve the photoelectric conversion efficiency of solar cells, decrease the cost of manufacture, application and power stability, are highly efficient solar cells have to solve the key problems in the development, manufacture.

Business school about the countries to promote healthy development of photovoltaic industry several opinions clearly put forward, on the new photovoltaic manufacturing project should satisfy monocrystalline silicon solar cell conversion efficiency of no less than 20% of the industry requirements.The conversion efficiency over 20% in the world today and can realize commercial production of the technical route, only the back contact battery (IBC), back passivation battery (PERC) and three heterojunction batteries.Compared with the former two technologies, heterojunction battery has better controllability, lower production cost and higher development prospects.

"Because of the battery can double heterojunction power generation, when positive to keep more than 20% of the conversion efficiency of power generation, can accept the back ground and other parts of the reflective, additional 3% of generating capacity. And double characteristics of the heterojunction battery can satisfy component at any Angle of special installation requirements, such as highway or railway sound insulation wall vertical installation of different quality and components can power about 30% more than conventional components."National 863 key project "MW class film heterojunction silicon/silicon solar battery industrialization of key technologies" head ciic fiber optic communications co., LTD., Shanghai, said the chairman Peng Dexiang efficient heterojunction solar cell conversion efficiency of a major breakthrough, is a revolutionary technology of the photovoltaic industry to ascend, for distributed solar power station and the family also use provides excellent products by solar power.

The expert thinks, efficient heterojunction solar cells will effectively promote industrial structure adjustment.In application of market demand for high-end technology products in short supply at home and abroad, is expected to break the foreign enterprise in the field of efficient heterojunction solar cell technology monopoly.

Association of Chinese circular economy committee, says li junfeng, director of the renewable energy branch of the development of photovoltaic technology will play a crucial role in the energy revolution.Chinese photovoltaic industry association, changzhou trina solar co., LTD., chairman and chief executive of unstoppable argues that as the generating cost less and less, photovoltaic power generation in China has a long-term development prospects, there's no substitute for energy.

It is understood that in order to further promote the development of photovoltaic industry in China, Shanghai ciic fiber optic communications co., LTD. Has been with the world's first and only a on efficient heterojunction solar cell manufacturing equipment form mass production manufacturer Ulvac reached cooperation, and to determine the cooperation development of industrialization of high efficient heterojunction solar cell conversion efficiency in more than 22% of the target.To enhance the application level of the project, as Shanghai ciic fiber optic communications co., LTD. Hubei eternal solar co., LTD., one of research and development of the photovoltaic battery information system and application, the study can timely understand the status of the pv power plant transient work, for heterojunction cells industrialization application will have very good push action.
