Description
Bembe C. Mackintosh and colleagues tackle trapped charge in lead-free solar materials in a 2026 study. Metal chalcohalides promise safer solar absorbers, yet charges often localize within picoseconds and stop moving. Swapping the metal in a mixed family was tested as a cure.
Lead and tin versions of the same framework took different crystal symmetries. Only the lead form showed the rapid trapping in the reported light tests, while the tin form kept conductivity for nanoseconds. Higher symmetry and electron behavior explain the gap as analyzed. The contrast gives a chemical rule for picking solar materials that keep charges mobile.
