Measuring open-circuit voltage (Voc) vs. light intensity (Suns) in solar cells permits the access of cell performance without the series resistance effect. This work shows the implementation of a Suns-Voc measurement system which consists of an off-the-shelf photograph flash-lamp, a digital oscilloscope and a specifically designed photodetector board with three silicon photodiodes that covers a light intensity measurement range from 10-5 to 102 suns. The whole system is controlled via USB ports from a personal computer allowing the measurement of cell characteristics (pseudo-dark and pseudo-light current density-voltage curves, as well as the pseudo fill factor and pseudo efficiency) automatically in a very short time. This work was supported in part by the Spanish Government under a FPU grant (FPU13/04381), and projects ENE2016-78933-C4-1-R, ENE2017-87671-C3-2-R and TEC2017-82305-R. The work was also supported in part by the project REFER COMRDI15-1-0036 funded by ACCIÓ and the European Regional Development Fund (FEDER). The authors wish to thank Mr. Miguel Garcia for its help in the mechanical and electrical photodetector interface development. |
