Introduction
A solar cell converts sunlight into usable electricity through a process known as the PV effect. Manufacturing solar cells requires several steps, including cleaning and texturing the wafer, applying anti-reflective coating and printing conductive metal grids to capture the electricity generated in the silicon wafer by the PV effect.
Characteristics
Crystalline silicon solar cells can be divided into monocrystalline and polycrystalline categories. Monocrystalline cells normally achieve higher efficiencies (16-18% efficiency) than polycrystalline cells (14-16% efficiency) by 2-3 percent. However than polycrystalline cells can get higher efficiencies in weakness light than monocrystalline cells. The quality of our solar cell reached international standard.
