In this study, we attempt the contribution of the silicon nanocrystal nc-Si luminescence phenomena to the performance of the conventional mc-Si solar cells. These nc-Si are embedded in the hydrogenated silicon nitride dielectric layers. The experimental results are obtained by different characterizations. They show that the optimum temperature is around 720°C with a good homogeneous distribution of nc-Si (3-5nm). However, to validate our results on silicon solar cells, we deposited silicon-rich silicon nitride layers on p-type (0.5ohm.cm) and diffused POCl3(40ohm/sq) substrates. Then, we performed thermal annealing at 720°C under mixture of gas (N2/H2) during one hour. The I-V measurements are carried out after the screen printing metallization and they showed 0.4% increase of the absolute efficiency.

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.
