We have a green, eternal and harmonious future, so that every household can easily use clean, inexhaustible solar energy, make the sky more pure, the river is clearer, all the creatures on the earth bathe in the harmonious sunshine, ENERGY willing Work hard with all people of insight to build a beautiful home on earth.

Polycrystalline silicon solar cell

Our products are classified according to strict appearance standards;
Our efficiency sorting consists of two steps:
1、First, we divide by efficiency;
2、Secondly, in the same gear position, we will make a second binning according to the working current; the narrow working current binning ensures the uniformity of the battery's electrical properties and avoids the mismatch problem with the components;
Through the full inspection of the resistance, the hot spot effect of the component product is reduced, and a good weak light response can be obtained at the same time;
Our calibration sheet comes from the ISE lab, and we perform rigorous GRR testing on the inspection system, which ensures the accuracy of our efficiency.
In order to further ensure the stability and dependability of the products, we produce a continuous system quality improvement management system and a strict data control system on site.

Solar cell characteristics

High photoelectric conversion efficiency and high reliability.
Unique diffusion technology to ensure uniformity of diffusion.
Advanced PECVD film-forming technology, the surface of the battery is coated with a deep blue silicon nitride anti-reflection film, the color is even and beautiful.
The back field and electrodes are fabricated using high quality metal paste to ensure good electrical conductivity, reliable adhesion and good electrode solderability.
High-precision screen printing and high flatness make the battery easy to automate and laser cut.
