Qinghai develops solar-grade monocrystalline silicon wafer testing enterprise standard
On the 27th, it was learned from the Science and Technology Department of Qinghai Province that through the successful implementation of the "Solar-grade 125×125 single crystal silicon wafer cutting process technology research project", Qinghai Province formulated the solar-grade monocrystalline silicon wafer testing enterprise standard in mid-June, and completed the preparation. Qinghai Province local standard "Quality requirements for solar grade monocrystalline silicon wafers". In order to make full use of the advantageous resources to develop the photovoltaic industry, Qinghai Science and Technology Department and Qinghai Huasi Co., Ltd. jointly completed the research on the cutting technology of monocrystalline silicon wafers, and improved the existing multi-line cutting and wafer cleaning processes. Advanced level. He Zhi, deputy director of the High-tech Development and Industrialization Department of the Science and Technology Department of Qinghai Province, introduced that the monocrystalline silicon wafer cutting process technology has enhanced the competitiveness of the product market and is an independent innovation achievement of the enterprise. Experts recommend implementing intellectual property protection as soon as possible. The establishment of the completed solar-grade monocrystalline silicon wafer testing enterprise standard is of great significance to the development of China's monocrystalline silicon industry.
