In the optimization of solar cell electrodes, contact resistance is an important aspect to consider. The magnitude of contact resistance is not only related to the contact geometry but also to the diffusion and sintering processes. Measuring contact resistivity can reflect issues present in the diffusion, electrode fabrication, and sintering processes. The TLM-STD contact resistivity tester offers two testing functions: Contact resistivity testing and line resistance testing, which can be switched between. The contact resistivity testing is primarily used to measure contact resistance, thin film resistance, and contact resistivity; The line resistance testing is used to measure the line resistance of grid lines.
