The influence of the Si–H2 bond on light-induced degradation and the thermal recovery of a-Si films and a-Si solar cells were studied. The influence of the Si–H2 bond on light-induced degradation depends on the impurity content in a-Si films, and light-induced degradation can be reduced by decreasing the Si–H2 bond density in a-Si films with impurity content of $10^{18}$ cm-3. The activation energy of the thermal recovery process was about 1.0 eV, and it did not depend on the Si–H2 bond density. However, an irreversible phenomenon was observed in film properties and solar cell characteristics with high Si–H2 bond density. It is thought that the structural flexibility of the Si–H2 bond is related to this irreversible phenomenon.
