Researchers have successfully produced large-area, ultra-thin organic photovoltaic modules using scalable solution-based printing processes, and transferred them onto lightweight and high-strength composite fabrics to create durable fabric-PV systems.
Thin-film photovoltaics with functional components on the order of a few microns, present an avenue toward realizing additive power onto any surface of interest without excessive addition in weight and topography. To date, demonstrations of such ultra-thin photovoltaics have been limited to small-scale devices, often prepared on glass carrier substrates with only a few layers solution-processed. We demonstrate large-area, ultra-thin organic photovoltaic (PV) modules produced with scalable solution-based printing processes for all layers. We further demonstrate their transfer onto light-weight and high-strength composite fabrics, resulting in durable fabric-PV systems similar to 50 microns thin, weighing under 1 gram over the module area (corresponding to an area density of 105 g m(-2)), and having a specific power of 370 W kg(-1). Integration of the ultra-thin modules onto composite fabrics lends mechanical resilience to allow these 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.
