Description
Andreas Schiller and colleagues present a two thousand twenty-four study of whether light changes ion movement inside perovskite solar cells. Mobile ions cause these cells' odd electrical behaviour and degradation. A long debate asked if illumination itself speeds ions up.
Simulations first showed that a familiar capacitance rise under light can arise purely from electronic currents screened by ions. A new capacitance-based test on complete devices was then proposed. Every cell type measured showed the signature of light-enhanced ion conductivity. The result reopens basic questions about what light does inside these promising solar materials.
