Features of Multicrystalline Solar Cell
1. Multicrystalline solar cells have reliable performance, high
photoelectric conversion performances, and usually are used in
large-scale applications and industrial production. The photoelectric
conversion rate can be up to 10% when the cells are manufactured in
large scale. It can reach 18% in laboratory.
2. We adopt unique diffusion technology to ensure uniformity of diffusion.
3. Our multicrystalline solar cells are coated with dark blue silicon
nitride anti-reflection film through advanced PECVD film technique.
5. Electrodes and the back surface are made by high-quality metal
slurry, resulting in good conductivity, reliable adhesion and have good
weldability characteristics.
6. We conduct quality improvement management system and strict data
control system to ensure multicrystalline solar cells are reliable and
stable.
7. Calibration film comes from ISE laboratory, while we carry out strict
GRR tests inspections, which ensures accuracy of multicrystalline solar
cells' energy conversion efficiency.

We PV Company is the major multicrystalline solar cell manufacturer
based in China. Quality of our solar cells is strictly controlled. For
raw materials, silicon wafers are categorized into different conversion
rates, by which wafers are further divided based on their working
current to ensure cells have uniform electric property. In addition,
comprehensive inspections are conducted on every solar cell, thus
ensuring maximum quality. They are classified depending on their
appearance, and are certified by UL, CE, etc. They have been exported to
Germany, Spain, Italy, Czech Republic, Belgium and other countries.
