Long-term degradation tests were carried out on amorphous silicon solar cells by light irradiation and current injection. The correlation of the degradation patterns and the lifetime estimation data in these two methods have confirmed the mutual stress conversion of light and current intensity. It is possible to estimate the lifetime of solar cells.
