In the PV industry, the production chain from quartz to solar cells usually involves 3 major types of companies focusing on all or only parts of the value chain: 1.) Producers of solar cells from quartz, which are companies that basically control the whole value chain. 2.) Producers of silicon wafers from quartz–. .
Before even making a silicon wafer, pure silicon is needed which needs to be recovered by reduction and purificationof the impure silicon dioxide in quartz. In this first step, crushed quartz is put in a special furnace, and then a. .
