... R0 is a reference resistance at a given temperature T0 (usually 273 or 293K). For common metals α is between 0.003 and 0.005 K-1. Superconductors: The resistance drops to zero for temperatures less than Tc. Highest Tc known: 160K. Usually only a few K. Discovered 1911 by KammerlinghOnnes in Leiden. ...

I–U RESTRICTIONS FOR AND BY SERIES RESISTANCE AVERAGING
... ABSTRACT: Several approaches have been published for analyzing local I–U curve parameter in order to estimate the contribution of each point of a solar cell to the global I–U curve. Nearly all of them use a one- or two-diode model for the description of the local as well as the global I–U curve. In ...
