To date, demonstrations of ultra-thin photovoltaics have been limited to small-scale devices, often prepared on glass carrier substrates with only a few layers solution-processed. Researchers at MIT have demonstrated large-area, ultra-thin organic photovoltaic (PV) modules produced with scalable solution-based printing processes for all layers. They were transferred onto lightweight and high-strength composite fabrics, resulting in durable fabric-PV systems ∼50 microns thin, weighing under 1 gram over the module are, and having a specific power of 370 W kg−1. Integration of the ultra-thin modules onto composite fabrics lends mechanical resilience to allow the fabric-PV systems to maintain their performance even after 500 roll-up cycles. This approach to decouple the manufacturing and integration of photovoltaics enables new opportunities in ubiquitous energy generation…read more. Open Access TECHNICAL ARTICLEÂ
