Measurements of contact resistivities for typical solar cell metallizations using this technique are reported to be in the mid 10<sup>-6</sup>Ω-cm<sup>2</sup>range. The relative importance of contact resistance compared to other sources of power loss in a solar cell is determined for a typical contact system.
It has already been mentioned that when finished c-Si solar cells are used for contact resistivity measurements, it is necessary to skip over contacts in order to measure the total resistance RT at different contact spacings d.
The concept of contact resistance is developed and contact resistance data for several different contact materials on both silicon and gallium arsenide over a range of doping densities are summarized. Finally, the requirements imposed by solar cells on contact resistance are detailed. Content may be subject to copyright.
The most common method used to calculate the contact resistivity of crystalline silicon (c-Si) solar cells is the transmission line method (TLM). This method was originally proposed by Shockley (1964) and further developed by Berger, 1972a, Berger, 1972b, Berger, 1969.
The relative importance of contact resistance compared to other sources of power loss in a solar cell is determined for a typical contact system. Expressions derived in order to make this comparison are useful for evaluating and optimizing a solar cell contact system.
