The Relationship

In the process of crystalline silicon solar cells production, there exist some solar cells whose reverse current is larger than 1.0 A because of silicon materials and process. If such solar cells are encapsulated into solar modules, hot-spot phenomenon will emerge in use. In this paper, the effect of reverse current on reliability of crystalline silicon solar modules was investigated. Based on the experiments, considering the different shaded rate of cells, the relation between reverse current of crystalline silicon solar cells and conduction of bypass diode was investigated for the first time. To avoid formation of hot spots and failure of solar modules, the reverse current should be smaller than 1.0 A for 125 mm × 125 mm monocrystalline silicon solar cells when the bias voltage is at −12 V.

AbstractWe have observed a significant light-induced increase in the open-circuit voltage (Voc) of mixed-phase hydrogenated silicon solar cells. In this study, we investigate the kinetics of the light-induced effects. The results show that the cells with different initial Voc have different kinetic behavior. For the cells with a low initial Voc (less than 0.8 V), the increase in Voc is slow and does not saturate for light-soaking time of up to 16 hours. For the cells with medium initial Voc (0.8 ∼ 0.95 V), the Voc increases rapidly and then saturates. Cells with high initial Voc (0.95 ∼ 0.98 V) show an initial increase in Voc, followed bya Voc decrease. All light-soaked cells exhibit a degradation in fill factor. The temperature dependence of the kinetics shows that light soaking at high temperatures causes Voc increase to saturate faster than at low temperatures. The observed results can be explained by our recently proposed two-diode equivalent-circuit model for mixed-phase solar cells.
