SINGLE AND MULTICRYSTALLINE SOLAR PANELS

MEANING OF CRYSTALLINEA three –dimensional structure consisting of periodically repeated ,identically constituted,congruent unit cells ,found abundantly in natural objects.crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystalline material.

SINGLE CRYSTALLINE CELLS

The single crystalline silicon cell is produced from pure silicon (single crystal) . Since the monocrystalline is pure and defect free the efficiency of cell will be higher.

MULTICRYSTALLINE SOLAR CELLS

In multy crystalline solar cell liquid silicon is used as raw material and multicrysstalline silicon was obtained followed by solidification process . The materials contain various crystalline sizes . Hence the efficiency of this type of cell is less than monocrystalline cell.
