Brief Introduction of Solar Cells

A solar cell is a fabricated device that converts the sun’s light into electricity. If we want to get right into it, a solar cell takes the energy from the sun’s light rays, by using the colliding light at the photon level to split apart the electron-hole pairs. When the photon hits the pair, they break, and one part goes north one part south. The stronger the sun, the quicker and more this happens. This process is called the photoelectric effect. The following diagram explains.

Usage of Polycrystalline Solar Cells

Solar cells are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current; our solar cells have passed IEC Certification. With high and stable quality, our cells can greatly improve the performance of Solar Modules.

Applications of Polycrystalline Solar Cells

Assemblies of photovoltaic cells are used to make solar modules which generate electrical power from sunlight, as distinguished from a "solar module" or "solar panel". A solar array generates solar power using solar energy.

Packaging & Delivery of Polycrystalline Solar Cells

Carton Box Package and Deliver by air. It should be noticed that it should be avoid of water, sunshine and moist.
