HJT High Efficiency Solar Cell Manufacturing
Whole-line Solution
The Whole-line Solution for HJT High Efficiency Cell Manufacturing, which completely covers the four processes of HJT cell production( as shown in the figure below), is independently developed by Maxwell. Through the manufacturing process for larger, thinner and half-sized wafers, the Whole-line Solution combines innovative process route, integrated MES intelligent system to further improve the conversion efficiency, yield and production capacity of solar cells, while reducing the production cost.
