“…The value of m approaches to 1 when the junction current in QNR of a solar cell is dominated by the diffusion mechanism. On the other hand, when carrier recombination in space charge region (SCR) dominates, the value of m approaches to 2 [30,31]. When the value of m is 1.2Zm >3.2, the charge recombination due to the coupled defects (depends on the strength of electric field) dominates the recombination mechanism.…”

“…From the obtained theoretical data as listed in Table 2, the series resistance, , shows a decreasing trend continuously with increase in the intensity of illumination. Using our previous work [50], the dynamic resistance of the DSSC can be determined for a given photogenerated current-voltage characteristic curve. The dynamic resistance for various illumination levels is listed in Table 2.…”

“…As the device temperature increases, negligible increase in short-circuit current is observed; however, the open-circuit voltage rapidly decreases due to the exponential dependence of the reverse saturation current on the cell temperature as given by (20) [50]. As a result of increased cell temperature, higher series resistance offers greater resistive power losses equivalent to 2 and thus reduces its performance by reducing efficiency.…”

The steady-state current-voltage curve and dynamic response of a dye-sensitized solar cell (DSSC) is mathematically modeled based on electrical equivalent circuit. The effect of temperature and illumination on the steady-state and dynamic parameters of dye-sensitized solar cells is studied. It is found that the dynamic resistance of DSSC decreases from 619.21 Ω to 90.34 Ω with the increase in illumination level from 200 W/m 2 to 800 W/m 2 . A positive temperature coefficient of dynamic resistance is observed. The interfacial charge transfer and recombination losses at the oxide/dye/electrolyte interface are found to be the most influential factor on the overall conversion efficiency and included in the mathematical model. The saturation current of rectifying diode and saturation current of recombination diode are responsible for the transfer recombination losses and have major influence on the overall conversion efficiency.

“…This procedure was used to compare the results obtained with those of an existing system cooled by natural air convection. Yadav et al [9] proposed a simplified model to evaluate the stationary and dynamic characteristics of a CPV. The results were compared with those obtained experimentally and showed that, when the concentration ratio is changed from 1 sun to 5.17 suns, the maximum power delivered by the concentrating photovoltaic system increases threefold.…”

The aim of the study is to evaluate the electric energy produced by flat-plate and concentrating photovoltaics plants located at the University of Calabria for a total peak power of 1.4 MW. The analyses were conducted using climate data from technical standards and from experimental data measured in the weather station of the Department of Mechanical, Energy and Management Engineering. For flat-plate photovoltaics, the predictive simplified Siegel method based on monthly average daily values of the external air temperature and global solar radiation on horizontal surface was compared with the results provided by TRNSYS dynamic software simulation. The hourly electrical energy produced by the concentrating photovoltaic arrays was obtained solely by TRNSYS software, since the simplified Siegel method is not applicable. The results obtained were used to compare the Siegel method and TRNSYS software dynamic calculation, and also to verify the influence of the climatic data used on the predicted performances of the photovoltaic plants. The provisional results of produced electrical energy were compared with the actual values of the hourly electrical consumption of the previous year in order to evaluate the percentage of annual self-consumption hours. Finally, a detailed economic analysis for the estimation of investment convenience was conducted.
