Water consumption for solar cell manufacturing could drop 79% with circular strategies

The article discusses how a solar cell manufacturing plant can reduce water consumption by up to 79% using circular water strategies. Researchers proposed the reuse of low contaminated wastewater (LCR) and a minimal liquid discharge (MLD) approach. These approaches can save water and reduce wastewater discharge without additional costs on production. Building new solar cell manufacturing plants in locations with less water availability is seen as feasible. Challenges include meeting marketability specifications of by-products and having local buyers for efficient transportation. The initial CAPEX investment for PERC production is higher in the case of a MLD setup.
