JA Solar 650W Modules: Stunning DeepBlue 5.0 Mass-Produced
Advantages of N- type TOPCon technologyCompared to other technologies, TOPCon 's advantages are mainly reflected in three aspects: process flow, cost, and reliability.1. Process flow:
TOPCon only requires coating the solder ribbon with flux and then welding it to the solar cells in strings using infrared heating, reducing the breakage rate. TOPCon has a main busbar spacing of 8~11mm , and the solder ribbon is distributed on both the front and back of the cell, which has the advantage of symmetrical distribution of current carrying capacity and stress, making the process simpler and achieving a yield of > 99.7% .
2. Cost:
TOPCon technology can be upgraded and modified based on PERC production lines, offering high equipment compatibility and relatively low investment costs. Jinko TOPCon has implemented a series of cost reduction measures based on the use of high-quality silicon wafers and encapsulation materials, resulting in a continuous decrease in module manufacturing costs, which are gradually approaching the cost level of PERC modules.
