The Digital New Energy DataBM. Com noted that on February 4, The Bureau of Ecology and Environment of Hefei City, Anhui Province, announced two photovoltaic cell projects, the MAX transformation project of high-efficiency solar cells and the 21 high-efficiency solar cells. 3 Environmental impact assessment documents of the upgrading and reconstruction project.
According to the announcement, the two photovoltaic cell projects are reconstruction projects with a total investment of 346.37 million yuan . The construction unit is Anhui Jinko Energy Co., Ltd. and the construction site is located in the factory area of Anhui Jinko Energy Co., Ltd. at the northeast corner of the intersection of Longxing Avenue and Ruquan Road, Hefei Circular Economy Demonstration Park, Feidong County, Hefei City, Anhui Province. The total investment of the
high-efficiency solar cell MAX transformation project is 194.37 million yuan . By adding laser and ALD tubular back passivation equipment, the double-sided passivation contact structure is upgraded. The EIA document shows that this structural optimization significantly improves the passivation effect and optical performance of the battery, thus increasing the double-sided rate of the battery by about 4% , while enhancing the overall conversion efficiency and reliability without adding new capacity . The total investment of the

high-efficiency solar cell 213 upgrading and transformation project is 152 million yuan, through the systematic and automated upgrading of the existing production line. Through the integration of key technology and equipment renewal and full-line automation, the project aims to achieve full capacity compatibility with 213 sizes, and significantly improve battery conversion efficiency without adding new capacity.
