The PERC double double glass module a new round of module technology upgrades ( 2)

According to introducing, the PERC double double glass component structure on the back of the battery printing process has changed, with the original PERC series production line compatible degree is high, the component part, USES the existing double glass production line can produce, production conditions are relatively mature. In early 2017, ja solar etc.

according to introducing, the PERC double module double glass changed structure on the back of the battery in the process of printing, high compatibility with the original PERC series production line. On module technology, existing double glass production line can be used for production, mass production conditions are relatively mature. High solar line assembly companies such as the beginning of 2017, has produced the PERC double double glass component. Traditional single emitter passivation of the PERC battery on the back, and after special treatment on the back of double-sided PERC battery affects the reflection of emitter passivation layer function, and easy to affect the battery positive conversion efficiency. However, because the back also can generate electricity, as long as the double power generation benefit together is still high, it has the development potential. Analysts said the double-sided PERC battery can use existing equipment production, increase the cost of manufacturing process itself is not high, the overall technology difficulty is still lower than N type double batteries. Therefore, before N mature technology, it is still worthy of attention. Besides with the advantages of high power output, determine the value of the component technology to the next thing is the feasibility of mass production. Only able to rapidly promote technology have a higher value. From the system into consideration, because the PERC double double glass components increase power and the advantage of 1500 v, also can effectively reduce the cost of BOS, such as land, bracket, junction box, etc. In the republic of the Yellow River chenyang 100 mw photovoltaic project as an example, if all adopt the PERC double and double glass 345 w modules, just install 90 mw can achieve the same capacity, this will reduce the nearly 10 mw of installed capacity, saves the project investment of nearly 60 million yuan. The PERC double double glass components also have double glass components of natural advantages. Glass structure wear-resisting, corrosion resistance, permeability is almost zero. To fundamentally eliminate the phenomenon of PID. Fire rating by ordinary crystalline silicon components C level upgraded to A level. 30 years power supply guarantee is widely used in various applications such as high temperature, high humidity, desert, seaside environment.
