4Creating Energy where there is light
• Low Cost: low temperature, ambient conditions, no clean room, no silicon, lower energy footprint
• Scalable: coating or printing technology, utilization of existing capacity
• Continuous: roll-to-roll high-volume production
Developing Low Cost, Scalable PV Manufacturing Process
Manufacturing Manufacturing ParadigmParadigm
Consequence: Thin, lightweight, flexible PV Product.
