Polysilicon is the starting material for mono- and multicrystalline silicon solar cells. The first step is to melt polysilicon in a crucible. Monocrystalline in-gots are pulled as single crystals from the melt us-ing the Czochralski process. Multicrystalline ingots are grown by directional solidification in a square quartz crucible.

Improvement of the efficiency of the furnace in terms of its design. The recycling of PV modules for silicon production can also contribute to reducing energy consumption and thus CO 2 emissions, depending on how much energy is required to process the recycled silicon material to the appropriate quality for wafers [2, 9].
PV module followed by cell manufacturing had the highest shares. In general, the calculated impacts are lower than those presented in previous studies, also for polysilicon, due to the update (most frequently reducing the quantity of materials and energy employed) of the inventories of the different stages of PV manufacturing.
