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.

This is a summary of: Liu, W. et al. Flexible solar cells based on foldable silicon wafers with blunted edges. Nature 617, 717–723 (2023).
