Variation of series resistance with temperature and illumination level in diffused junction poly- and single-crystalline silicon solar cells

Temperature dependence of I–V characteristics and performance parameters of silicon solar cell

“…Series resistance is known to affect CF adversely. Arora et al [2] have observed that R s decreases more rapidly with T in the lowtemperature region (100-250 K) in poly silicon cells as compared to that in single-crystal cells. On the other hand, Ding et al [3] have found that R s increases with temperature.…”

“…(3) along with R s and R sh control the effect of temperature on V oc , CF and Z of the cell. Surprisingly, however, a very few studies have been reported in literature on the temperature dependence of diode parameters [2][3][4][5]. Series resistance is known to affect CF adversely.…”

Robust series resistance estimation for diagnostics of photovoltaic modules

“…Although the resistivity of metallic contacts and interconnections increases linearly with temperature, the dependency of the panel's overall series resistance, including the internal resistivity of the junction is not banal, as the doped semiconductor conductivity -depending on the doping level -shows a non-linear function of temperature [21]. In [22] has been shown results indicating that the series resistance of crystalline silicone cells is decreasing with temperature.…”

“…In [22] has been shown results indicating that the series resistance of crystalline silicone cells is decreasing with temperature. On the other hand, the authors of [23] and [21] conclude that the series Effect of irradiation on the series resistance estimation for the BPMSX120 PV panel. Using the slope translation method, the irradiance dependency is greatly reduced -at irradiations above 20% of STC, the estimation result is quasi-independent of irradiation.…”

Short flash and constant load PV-module tester

“…We did not include this effect here, because it is relatively small [10], and in our measurement scheme it would be disguised as a further increase of capacitance with voltage. In principle one could also consider a dependence of the series resistance on the illumination level [11], but this effect is much smaller than that of the capacitance and was neglected here. The variables in (1) and (2) can be grouped into measured data on the one hand, and into parameters to be obtained from the data on the other.…”
