in addition, due to the manufacturing process of two kinds of solar cell materials, polycrystalline silicon solar cell manufacturing process consumes less energy than monocrystalline silicon solar cell is about 30%, so the polycrystalline silicon solar cells account for a growing share of the total global solar cell production, and manufacturing costs will also be significantly smaller than that of single crystal silicon cell, so using polycrystalline silicon solar cells will be more efficient, more environmentally friendly.
