Open circuit voltage temperature coefficients vs. concentration: Theory, indoor measurements, and outdoor measurements

Abstract

Current-voltage characteristics of multijunction M-V solar cells from several different vendors were measured at different light concentrations and temperatures. Measurements were taken indoors using flash lamp solar simulators and outdoors under natural sunlight. The change in open-circuit voltage with temperature was measured. Modeled results, indoor measurements, and outdoor measurements are compared. © 2012 American Institute of Physics.
