“…Figure 8 also shows that with the ΔT value increasing, the rangeability of δJsc will be at least an order of magnitude smaller than those of δVoc, δFF and δη, which is in agreement with other results related with the variations of the output parameters with temperature [16,46]. According to [16], when the temperature of c-Si SC decrease, photocurrent and reverse saturation current will remain basically unchanged and decrease, respectively, so the variations of the δJsc values with ΔT are mainly determined by reverse saturation current.…”

Operating temperature is a key factor affecting the output power of a crystalline silicon solar cell (c-Si SC). Based on solving basic semiconductor equations, Maxwell equations and heat flow equations by finite difference method, this work has theoretically investigated the influences of microfluidic cooling system on the temperature distributions and output parameters of an industrial c-Si SC packaged as a module form, where the cooling system is installed the interface between the aluminum electrode and back ethylene vinyl acetate layer and the cooling medium flowing through microchannel is selected as water. Under the influences of the cooling system, the back surface temperature of the c-Si SC is fixed at about water temperature and the front surface temperature will decrease with the water temperature decreasing. The temperature distributions of c-Si active layer and aluminum layer decrease approximately linearly along the two layer’s thickness directions. The cooling effects of the cooling system are mainly determined by water temperature and when the filling factor of microchannel is larger than 0.1, its influences on the temperature distribution of the c-Si SC are small. In the environmental temperature range from -15℃ to 60℃, the increase rates of Voc, FF and η per degree Celsius with the water temperature decreasing are about 0.0014V, 0.036% and 0.05%, respectively.

“…Solar panel electrical energy is produced from the direct transformation of solar radiation, where this energy conversion is conducted using PV cells based on a physical phenomenon known as the photovoltaic effect [5]. PV cells generates a potential difference and become a source of electric current when the surface of this cell is exposed to the sunlight [6].…”

Partial shading (PS) has a significant impact on the decrease in efficiency of photovoltaic (PV) array and performance of maximum power point tracking (MPPT) that must be addressed. We conduct an analysis and evaluation of local maximum power point (LMPP) in terms of quantity, and global maximum power point (GMPP) in terms of magnitude and diversity. Simulation is carried out using single diode ideal model and nine generic PS patterns that are specifically designed to bring up the substantial characteristics of the LMPP and GMPP and applied to series-parallel (SP) and total cross-tied (TCT) configurations. The SP configuration has LMPP with two, three, and four peaks, appearing three times each. The TCT configuration has two peaks that appear six times, three peaks that appear once, and four peaks that appear twice. The SP configuration experiences power losses ranging from 56% to 72%, while the TCT configuration has power losses ranging from 52% to 64%. The SP configuration generates a maximum voltage of 76.64 volts and a minimum of 39.20 volts, while the TCT configuration generates a maximum voltage of 77.62 volts and a minimum of 58.21 volts. With a smaller number of LMPP, a larger magnitude of GMPP parameters, and lower diversity, TCT exhibits better characteristics and performance compared to SP.

“…In addition, many works have shown that temperature increase has strong influences on electronic and intrinsic properties of semiconductor materials and photovoltaic cells (Reggiani et al, 2000;Souza and Sousa, 2019;Dhar et al, 2005;Alkuhayli et al, 2021;Amar et al, 2021;Kabbani and Honnurvali, 2021;Medekhel et al, 2022;Santos et al, 2022). Reggiani et al (2000) showed the strong decrease of the mobility of the electrons and the holes with temperature increase in silicon devices.…”

Studies on concentrated light influence do not take into account the effect of the heating and this proves to be harmful on photovoltaic parameters. The main purpose of this work is to study the effects of light concentration and the heating caused by this concentration on intrinsic properties and carrier density profile. A thermal model of the PV cell is proposed. By applying the power balance at the steady-state, the PV cell thermal equation is determined. The resolution of this equation leads to temperature profile which shows a rapid increase with light concentration. The mobility n  and diffusion n D coefficients of electrons increase to reach their maxima, respectively 2 1 1 max ( ) 1895,31 n cm V s    at C=6,77 Suns where temperature is T=430,92 K and 21 max ( ) 76,55 . n D cm s   at C= 12,59 Suns where temperature is T=508,24; before decreasing. However, for the holes these parameters decrease slowly with concentration increase. Silicon gap energy decreases while electrons intrinsic density increases with increasing concentration. The variations of these parameters are explained on one hand by their dependence on temperature but also by temperature profile with concentration. An electrical model of the PV cell under variable concentration is also proposed and from which the carrier's density is determined. It emerges that the carrier density increases significantly with concentration ratio. This fact is explained by the photo-generation increase with concentration. And also, by thermal generation increase linked to temperature increases with concentration increase. Results also show that carriers density is greater in the rear side compared to the zone near the junction in opposite to authors who did not take into account temperature effect and who showed that carriers density is greater at the illuminated face.
