Series resistance is a fundamental power-limiting factor for a solar cell. It is known to depend on the ohmic losses due to the metal contact resistance, the metal-semiconductor contact resistance, the substrate resistance, and the emitter sheet resistance. A typical operating approach consists of indirect measurements of the total series resistance. Our method, based on photoluminescence, is capable of generating an illuminated current-voltage curve free from the effect of the contact series resistance, giving an immediate idea of true cell performance. © 2004 American Institute of Physics.
