How are Epishine’s indoor solar cells manufactured using roll-to-roll?

Roll-to-roll (R2R) printing is a continuous manufacturing process, where functional layers are printed onto a flexible substrate that moves steadily from one roll to another —an approach widely used in printed flexible electronics.  

 Instead of producing solar cells in separate, sheet based steps, R2R enables continuous production, more like a printing press than a traditional factory line. R2R manufacturing also makes it possible to deliver the indoor solar cells on rolls, which can simplify the next steps in the customer’s integration process for light energy harvesting applications.
