About Photovoltaic Energy Storage1. Introduction. Light-induced degradation (LID) refers to a loss in the silicon solar cell efficiency that is observed during excess carrier injection by above-bandgap illumination [1] or forward biasing [2].LID is seen as a decrease in the solar cell short-circuit current and the open-circuit voltage [3], caused by increased minority-carrier …
