Thin film’s lower cost compared to crystalline solar cells is achieved by a simpler roll to roll manufacturing process which allows Xunlight to produce thin film solar cells on rolls of thin stainless steel substrates, three feet wide and up to one mile long. Xunlight’s unique manufacturing process only uses a small amount of silicon which also helps reduce the cost of solar panels. What do you think about thin film solar and Xunlight’s roll to roll manufacturing process?
