Base Resistance

Generated current typically flows perpendicular to the cell surface from the bulk of the cell and then laterally through the top doped layer until it is collected at a top surface contact.

The resistance and current of the base is assumed to be constant. The resistance to the current of the bulk component of the cell, or the "bulk resistance", Rb, is defined as:

恒大彩票网址是多少taking into account the thickness of the material. Where:

l = length of conducting (resistive) path
ρb= "bulk resistivity" (inverse of conductivity) of the bulk cell material (0.5 - 5.0 Ω cm for a typical silicon solar cell)
A = cell area, and
恒大彩票网址是多少 w = width of bulk region of cell.
