TLDR
In this paper, the authors used the measured "J/sub SC/-V/sub OC/ curve" of a solar cell as an approximation to the unknown R/sub S/-corrected I-V curve and determined the "lumped series resistance" in dark and illuminated operating conditions (R/sub s.dark/ and R/ sub s.light/) from the voltage shift between the "J /sub SC/V/ sub O/C curve" and the dark and illumination I -V curve, respectively.Abstract:
Measurements of the series resistance R/sub S/ are important for the localisation of dominant loss mechanisms in photovoltaic devices. The new measurement technique presented in this work uses the measured "J/sub SC/-V/sub OC/ curve" of a solar cell as an approximation to the unknown R/sub S/-corrected I-V curve and determines the "lumped series resistance" in dark and illuminated operating conditions (R/sub s.dark/ and R/sub s.light/) from the voltage shift between the "J/sub SC/-V/sub O/C curve" and the dark and illuminated I-V curve, respectively. Owing to multidimensional effects in practical devices, the lumped series resistance depends on the operating condition of the cell (i.e., dark or illuminated I-V measurements) and on the current density flowing through the device. This work not only provides a new, powerful method for the determination of the lumped series resistance of photovoltaic devices, but also considerably improves the general understanding of ohmic power loss effects in silicon solar cells. >read more
