Light-induced lifetime degradation effects are frequently observed in many silicon-based materials for solar cell production. The most prominent one is the boron-oxygen (BO) defect activated under illumination in boron-doped Czochralski-grown silicon (Cz-Si) 1.
In the present study, we examine, whether the light- and elevated-temperature-induced lifetime degradation (LeTID) observed on Ga-doped Cz-Si wafers is also the cause of the existing but small instabilities observed in solar cells made on Ga-doped Cz-Si wafers.
It has been known that amorphous silicon/crystalline silicon heterojunction solar cells (HJT cells) can be improved by light-thermal processes. The present work aims to acquire a further understanding of the effect of illumination intensity and temperatures in a broader range and the roles of light and heat in the improvement.

The extent of degradation at 140 °C amounts to 0.4% abs of the initial conversion efficiency of 22.1% compared to 0.15% abs at 80 °C. The extent of the efficiency degradation in the examined solar cells is significantly lower (by a factor of ~ 5) compared to solar cells made on B-doped Cz-Si wafers.
Besides pure MA and FA-based perovskite, other perovskites with differing compositions of halide anions (I − and Br −) and organic cations (MA + and FA +) have been heavily investigated to see the effect of phase transition on thermal stability, device performance and lifetime at 85°C of solar cells.
