Irrespective of the device types, the SiO-encapsulated cells show no degradation, except for the small decrease in the EL emission for passivated cells after 60 min, which might be due to the gradual erosion of SiO by atomic oxygen.
In the most refined versions 21, 22, a discretization of the solar cell is made in the plane and a two-diode model is applied to each node of the mesh to predict the electric response of the semiconductor. In case of hot spots, however, it was indeed necessary to modify the value of the series resistance in the nodes close to a crack.
In particular, the sensitivity of silicon heterojunction solar cells to high temperatures and moisture is a concern. Sodium (Na) in combination with humidity is widely considered one of the causes of degradation in silicon heterojunction solar cells. Yet, a comprehensive understanding of the mechanisms behind Na-induced decay remains lacking.
