The PV manufacturing process creates hazardous waste, which primarily stems from the use of toxic materials such as cadmium and silicon, along with the types of solvents and chemicals employed in the production. Energy consumption during manufacturing is significant, leading to a considerable carbon footprint associated with this process. The. The growth of solar energy over the years has generated millions of tonnes of panel waste that usually end up in landfills. Maintaining efficiency requires renewing solar cells, creating waste.
