Cadmium, indium, gallium, lead, and selenium are all used in solar panel production.
Silane gas is used in the production of Si wafers. There are several silane leaks reported each year in the US during the production of silicon wafers. Silane can spontaneously explode.Manufacturing of silane and trichlorosilane results in waste silicon tetrachloride, which is nasty stuff.
Sulfur hexafluoride is used in cleaning the reaction chambers that silicone is produced in. It's a very potent green house gas. In fact, it's 25,000 times more potent than CO2.
sodium hydroxide and potassium hydroxide are used on the cut edges of silicone wafers. Hydrochloric acid, sulfuric acid, nitric acid and hydrogen fluoride are used to clean the silicone wafers during production. Phosphine or arsine gas is used in the doping of the semiconductor. Phosphorous oxychloride, phosphorous trichloride, boron bromide and boron trichloride are also used during the doping process.
Do I really need to go on? Or is there any point as you obviously choose to ignore reality.
