When you imagine a solar cell what usually comes to mind is a rigid block. But what if solar cells could be fully foldable? Then, a bunch of new applications would open up for them from wearables to gadgets. Now, engineers at Pusan National University in Korea have developed exactly this type of solar cell. But achieving it was no easy task. “Unlike merely flexible electronics, foldable devices are subject to much harsher deformations, with folding radii as small as 0.5 mm. This is not possible with conventional ultra-thin glass substrates and metal oxide transparent conductors, which can be made flexible but never fully foldable, said in a statement Professor Il Jeon of Pusan National University, Korea.
