The manufacturing of solar modules is a complex process that involves the use of various chemicals at each stage to construct cells and the elements that surround them. Chemical companies contribute to the supply chain by providing solar silicon, assorted films, glass, silicones, aluminum frames, and other components and materials to ingot, wafer, cell manufacturers, laminators, and module assemblers. This report quantifies revenues at various points in the supply chain to provide sector sizing for several materials for the current year and forecasts until 2030.
