Caption: In the initial state (left), the voids' internal surfaces are saturated with hydrogen atoms so that no defects are observed. Light-induced charge carriers (h+) destabilize atomic bonds. The breaking of atomic bonds causes defects (indicated by the vertical arrows on the right hand side), which translates to reduced solar cell efficiency.
