  • Discover the remarkable power of MIT's ultralight fabric solar cells- 18x more efficient than traditional solar panels, capturing energy from any surface and resistant to 500+ cycles of rolling & unrolling. Embark on a greener future with sustainable energy generation.

Cambridge, Massachusetts — Engineers at the Massachusetts Institute of Technology (MIT) have achieved a major breakthrough in solar technology with their creation of ultralight fabric solar cells. These solar cells, thinner than a human hair and just a fraction of the weight of standard solar panels, possess the remarkable ability to transform nearly any surface into a viable power source.

This groundbreaking innovation has been made possible through the utilization of semiconducting inks and scalable printing techniques. The result is a remarkable power-per-kilogram production rate that is 18 times greater than traditional solar panels.

The production process of these revolutionary solar cells relies on electronic inks and entirely printable materials. It involves the deposition of nanomaterial layers onto a substrate that is a mere 3 microns thick using a slot-die coater. By adding an electrode through screen printing, the final solar module becomes incredibly thin, measuring just 15 microns. To address the issue of fragility, MIT has incorporated Dyneema, an exceptionally strong fabric, as a substrate. The solar cells are secured in place with UV-curable glue. When tested on Dyneema, these cells generated an impressive 370 watts-per-kilogram, clearly outperforming traditional solar cells.

Furthermore, the ultralight fabric solar cells maintain their power generation capability, with over 90% retained, even after undergoing the stress of being rolled and unrolled 500 times. The MIT research team is actively exploring environmentally friendly packaging options and other solutions for environmental protection.

In summary, MIT's ultralight fabric solar cells represent a groundbreaking advancement in solar technology, boasting exceptional efficiency and portability. Their unique capability to capture solar energy from a wide range of surfaces holds immense promise for sustainable energy generation. While durability challenges remain, this innovative approach has the potential to revolutionize the solar industry, offering a greener and more adaptable solution for renewable power generation.
