Massachusetts Institute of Technology (MIT) engineers published a paper in the latest issue of the journal "Little Methods", saying that they have developed an ultra-light solar cell that can quickly and easily turn any surface into a power source. This solar cell, which is thinner than a human hair, is attached to a piece of fabric, weighs only one percent of traditional solar panels, but generates 18 times more electricity per kilogram, and can be integrated into sails, disaster relief tents and tarps, drone wings and various building surfaces.
The test results show that the stand-alone solar cell can generate 730 watts of power per kilogram, and if it is adhered to the high-strength "Dynamic" fabric, it can generate about 370 watts of power per kilogram, which is 18 times that of traditional solar cells. Moreover, even after rolling and unfolding the fabric solar cell more than 500 times, it still maintains more than 90% of its initial power generation capacity. This method of battery production can be scaled up to produce flexible batteries with larger areas. The researchers stress that while their solar cells are lighter and more flexible than conventional batteries, the carbon-based organic material from which the cells are made interacts with moisture and oxygen in the air, potentially degrading the performance of the cells, necessitating the need to wrap another material To protect the battery from the environment, they are currently developing ultra-thin packaging solutions.
