The use of polycrystalline silicon in the production of solar cells requires less material and therefore provides higher profits and increased manufacturing throughput. Polycrystalline silicon does not need to be deposited on a silicon wafer to form a solar cell, rather it can be deposited on other, cheaper materials, thus.

Silicon''s ability to absorb sunlight and its semiconductor nature makes it an ideal material for solar cells. When sunlight hits the silicon wafer in a solar cell, it excites the electrons, causing them to move and create an electric current. There are two main types of silicon used in solar cells: monocrystalline and polycrystalline silicon

Due to these defects, polycrystalline cells absorb less solar energy, produce consequently less electricity and are thus less efficient than monocrystalline silicon (mono-Si) cells. Due to their slightly lower efficiency, poly-Si/ mc-Si cells are conventionally a bit larger, resulting in comparably larger PV modules, too. This factor has to be considered if space is limited. Nevertheless, the
