How Solar Cells Work
Photovoltaic cells, also known as PV or solar cells, are created from semiconductor material such as silicon. The process of solar conversion works as follows:
1) When light strikes the cells, a specific portion or "band" of the light wave is absorbed by the material.
2) That solar energy causes the semiconductor material to release electrons.
3) The semiconductor material is positioned within an electrical field by using negatively and positively charged silicon (n-type and p-type), so that all electrons set "fee" from the material are forced to flow-generating electrical current.

Solar Cells Manufacturing Process
1.Small Test Machine
2. Big Test Equipment
Especially mentioned that you can't multimeter to test the solar cells, it is not the right way!
To test solar cell should use the professional equipment, please check above photos to see how we test.
Please noted that, there have many PM points on the solar cells, use multimeter only can touch 1 or 2 PM point, it is hard to make the current come out. You can see our test equipment; there have many metal needles, almost touch the whole solar cell busbar. Normally, to use the multimeter, no matter what kind solar cells, sometime there only very less current come out, like 0.1-0.5A!
Solar Cells is very fragile, to want to delivery to you safely and quickly, we will make a very stronger and careful packaging.
