Time to shine: Scientists reveal at an atomic scale how chlorine stabilizes next-gen solar cells

Researchers have imaged the atoms at the surface of the light-absorbing layer in a new type of next-generation solar cells, made from a crystal material called metal-halide perovskite. Their findings have solved a long-standing mystery in the field of solar power technology, showing how power-boosting and stability-enhancing chlorine is incorporated into the perovskite material.
