What is the difference between sheet-based manufacturing and roll-to-roll manufacturing?

Many indoor solar cell manufacturing methods today are sheet-based; meaning materials are processed in separate batches and stopped between steps, instead of in a continuous roll-to-roll process. Epishine has chosen roll-to-roll printing as it enables high-volume processing needed for production with strong benefits of cost and energy efficiency compared to sheet-based production methods. 

 With just 1 gram of active semiconductor material, Epishine can produce several square meters of solar cell surface. Compared to conventional solar manufacturing, which often requires large facilities and heavy infrastructure, Epishine’s roll-to-roll process uses a fraction of the footprint, reducing material use, energy demand, and required floor space.
