The discovery of nanoscale changes deep inside hybrid perovskites could shed light on developing low-cost, high-efficiency solar cells. Using X-ray beams and lasers, a team of researchers discovered how the movement of ions in hybrid perovskites causes certain regions within the material to become better solar cells than other parts.
