Flexible solar cells made with crystalline silicon
Although crystalline silicon (c-Si) solar cells were developed nearly 70 years ago, their use is still limited. Tailoring the structural symmetry on the edges of textured c-Si wafers changes their fracture mechanism such that they can be used to fabricate flexible solar cells with a bending radius of about 8 millimetres.
