Roll-to-roll processing is a technology which is still in development. If semiconductor devices can be fabricated in this way on large substrates, many devices could be fabricated at a fraction of the cost of traditional semiconductor manufacturing methods. Most notably would be solar cells, which are still prohibitively expensive for most markets, due to the high-cost per unit area of traditional crystalline silicon manufacturing. Other applications could arise, which take advantage of the flexible nature of the substrates, such as electronics embedded into clothing, large-area flexible displays, and roll-up portable displays.
