Effect of parasitic Resistances

Both the magnitude and impact of series and shunt resistance depend on the geometry of the solar cell, at the operating point of the solar cell. Since the value of resistance will depend on the area of the solar cell, when comparing the series resistance of solar cells which may have different areas, a common unit for resistance is in Ωcm 2 .

Observations of contact resistance in TOPCon and PERC solar cells

In this article we investigate the observation of increased contact resistance in both PERC and TOPCon solar cells linked to hydrogen dynamics at the interface. We study the changes in series resistance (R S) as a result of applied forward and reverse bias in the temperature range from 350 C–400 C. ...
