Si
Crystalline silicon material is the most important photovoltaic material, and its properties are gray black with metallic luster, high melting point (1410 ℃), high hardness, brittleness and inactive chemical properties at room temperature. Its market share is more than 90%, and it will still be the mainstream material of solar cells for a long time in the future.
CasCrysTech (CCT) provides high quality silicon wafers which can be customized upon customer's requirements.
