MIT scientists make photo voltaic panels as skinny as a human hair

Six years in the past, an MIT engineering crew on the college’s Natural and Nanostructured Electronics Laboratory (ONE Lab) developed a photo voltaic cell so skinny it may relaxation atop a cleaning soap bubble. Whereas spectacular, the manufacturing necessities and price sadly prohibited any viable large-scale plans. This week, nonetheless, ONE Lab revealed a brand new, equally ultra-thin photo voltaic cell materials that’s one-hundredth the load of standard panels, whereas additionally probably producing 18 occasions extra power-per-kilogram in comparison with conventional photo voltaic expertise. Not solely that, however its manufacturing strategies present promising potential for scalability and main manufacturing.

As a press launch from MIT explains, highly effective photo voltaic cells’ fragile natures require thick glass and aluminum encasements for defense, thus limiting their versatility and implementation alternatives. Utilizing semiconducting inks printed onto materials thinner than a single strand of human hair, the crew was capable of subsequently glue the panels onto a layer of Dyneema, a protecting, ultra-lightweight composite cloth weighing solely 13 grams-per-square meter. The resultant microns-thin sheet may then be laminated atop quite a lot of surfaces and supplies—assume tent exteriors to generate energy throughout catastrophe reduction efforts, or drone wings to increase their potential flight occasions.

Regardless of its extremely miniature design, the brand new materials packs loads of storage potential. Talking with MIT, Mayuran Saravanapavanantham, one of many crew’s paper co-authors and {an electrical} engineering and pc science graduate pupil, provided a typical house rooftop photo voltaic array for comparability. “A typical rooftop photo voltaic set up in Massachusetts is about 8,000 watts,” Saravanapavanantham defined. “To generate that very same quantity of energy, our cloth photovoltaics would solely add about 20 kilograms (44 kilos) to the roof of a home.”

Sturdiness can also be a key part for any viable photo voltaic cell array, a function the ONE Lab crew demonstrated in its new design by reportedly rolling and unrolling the material over 500 occasions, which solely resulted in a lower than 10 % loss in potential energy technology.

Sadly, MIT’s spectacular photo voltaic cloth isn’t fairly prepared to stitch into your garments simply but. The crew continues to be trying to find the correct materials to encase the product—as a result of the cells are produced from carbon-based natural materials, publicity to the pure moisture and oxygen within the air would lead to a fast decline in capabilities.

“We’re working to take away as a lot of the non-solar-active materials as doable whereas nonetheless retaining the shape issue and efficiency of those ultralight and versatile photo voltaic constructions,” Jeremiah Mwaura, one of many paper’s further co-authors, defined to MIT. As soon as that drawback is addressed, the photo voltaic cloth may discover its method onto numerous surfaces so as to add much-needed inexperienced, renewable energy to each day life.
