2022year4month1day The conventional method starts with the extraction of silica from silica source such as quartz sand to produce chemical precursors. These precursors are then used for the production of SiO 2 . This conventional method contributes to global warming due to large amount of carbon dioxide (CO 2 ) emitted from the extraction process [9] .

The only argument against crystalline Si as the ideal PV material both now and in the future pertains to the fourth criterion. That is, the availability, collection, and manufacture of crystalline Si are extremely problematic. More precisely, because Si in nature is found only as impure, oxidized sand (silica/SiO 2) or silicates (a salt with SiO 4–x (4–2x)–), the
