Solar cell future development

- Aug 02, 2018-

In terms of specific operations: the research of polycrystalline silicon solar cells should combine the research and introduction, and establish a production line with an annual production capacity of megawatts as soon as possible; monocrystalline silicon solar cells focus on improving the efficiency of components and reducing production costs; accelerating the development of new solar energy battery. Specific standards: The main technical and economic indicators for the establishment of megawatt-class polycrystalline silicon solar cell module production line: component efficiency 13%, component life expectancy 20 to 25 years; technical transformation of monocrystalline silicon solar cell module production line main technical and economic indicators: component efficiency 14% ~ 15%, component life is 20 to 25 years.

In order to develop rapidly under the existing technical conditions, the solar cell industry should realize the industrialization of small-scale optical power sources as soon as possible; focus on the development of serialized, standardized, commercialized research and integration of photovoltaic power generation technologies for independent operation of photovoltaic power plants below 100 kW. Scale application is ready.

In terms of specific standards: low-power photovoltaic power supply industrialization power range: kilowatt-class, hundred-watt-level industrial scale: total capacity greater than 1 megawatt system cost: more than 30% lower than the average price of "eight five"; solar power plant series Chemicalization, standardization, and commercialization. Power range: 10 kW ~ 100 kW system cost: more than 30% lower than the "eight-five" average price; grid-connected photovoltaic power generation technology research and demonstration. The preliminary research of MW-level grid-connected photovoltaic power station, the development of 10 kW grid-connected photovoltaic demonstration power station, 100 kW grid-connected photovoltaic power station inverter, photovoltaic power station operation and power system related technology research.
