“…It appears through these studies that the increase of illumination power comes with an increase of the density of carriers in the base of the solar cell [9] [10]. Some studies put also in evidence that external parameters such as magnetic field [10] [11] electric field [11] [12], light concentration [10] [13] can influence the diffusion coefficient of a silicon solar cell.…”

“…Even though the increase of the intensity of the light illumination leads to an increase of the carrier photogenaration and then to an increase of the density of carriers in the base [10], this situation generates an increase of the temperature in the base of the solar cell [14] [15] [16]. In experimental studies [14] [17] [18], it was proved that the short circuit current and the conversion efficiency increases with the increase of the temperature when the open circuit voltage de-creases.…”

The efficiency of a silicon solar cell is directly linked to the quantity of carrier photogenerated in its base. It increases with the increase of the quantity of carrier in the base of the solar cell. The carrier density in the base of the solar cell increases with the increase of the flux of photons that crosses the solar cell. One of the methods used to increase the flux of photon on the illuminated side of the solar cell is the intensification of the illumination light. However, the intensification of the light come with the increase of the energy released by thermalization, the collision between carriers, their braking due to the carriers concentration gradient electric field which lead to increase the temperature in the base of the solar cell. This work presents a 3-D study, of the effect of the temperature on the electronic parameters of a polycrystalline silicon solar under intense light illumination. The electronic parameters on which we analyze the temperature effect are: the mobility of solar cell carriers (electrons and holes), their diffusion coefficient, their diffusion length and their distribution in the bulk of the base. To study the effect of the temperature on electronic parameters, we take into account, the dependence of carriers (electrons and holes) mobility with the temperature (μ n, (T) μ p (T)). Then, the resolution of the continuity equation, which is a function of the carriers gradient electric field and the carriers mobility, leads to the expressions of the diffusion coefficient, the diffusion length, and the density of carriers which are function of the temperature. Then, we studied the effects of the temperature on the diffusion parameters in order to explain their effect on the behavior the carriers distribution in intermediate, short circuit and open circuit operating modes at several positions in the base depth. It appears through this study that the diffusion coefficient and the diffusion length decrease with the increase of 292 Smart Grid and Renewable Energy the temperature. We observe also that with the increase of the temperature, the density of carriers in the base of the solar cell in short circuit and open voltage operating modes increases. In intermediate operating mode, the density of carriers increases also with the temperature but it is function of the base depth.

“…Except the curve of θ � π/2 rad, which is similar to the traditional curve of electric power [12][13][14][15][16] because the electromagnetic field is null (absence of radio wave) and does not impact it, the other curves present four zones but three very significant. e three very significant zones of the curves are marked in Figure 2.…”

This paper investigated, by one-dimensional modelling, the effects of reverse polarisation of an electromagnetic field, generated by an amplitude modulation radio antenna, on the efficiency of a silicon PV cell. Through a simulation, the effects of both the incidence angle and the electromagnetic field magnitude on the power output of the PV cell are analyzed. The power output curves against the junction dynamic velocity are used to find the junction dynamic velocity at the equilibrium, the maximum power output, and the efficiency of the PV cell. The results have shown that the presence of important electromagnetic fields in the neighborhood of a silicon PV cell decreases its performance.

The reliability of energy supplies is required for sensing devices to collect data continuously in long-term monitoring. [7] Rechargeable batteries are unable to meet the sustainable energy demand due to their inherent defects of limited working time period. Furthermore, bulky and rigid power supply devices are inappropriate for portable and wearable electronics that require lightness and flexibility. [8] The self-powered sensors based on energy harvesting technology are an attractive alternative for powering these portable and wearable electronic devices. [9][10] The energy harvesting is the conversion of ambient energy into electrical energy. Due to the cost-effectiveness and high output characteristics, solar cells that convert solar energy into electricity have become the most widely used energy harvesting devices. However, on cloudy, rainy days, or at night, the supply of solar energy is severely reduced. Moreover, the contaminants on the surface of the solar cell can degrade the energy conversion efficiency of a solar cell. [11] To address these issues, solar cells can be integrated with other suitable energy harvesters to sustainably generate electricity under various environmental conditions.The mechanical energy from rain drops, wind flowing, or the human body can be great energy resources since these energies are eco-friendly and widely distributed in the living environment. The triboelectric nanogenerators (TENGs) and piezoelectric nanogenerators (PENGs) can harvest these energy resources. The TENGs are based on the coupling of contact electrification and electrostatic induction. [12][13] In earlier research, the water demonstrated to be one of the materials to generate triboelectricity and the contact-electrification on the solid/liquid interfaces was also studied. [14] On the other hand, the PENGs can generate electrical power under a tiny deformation. [15] The TENGs and PENGs are easy to be integrated with other energy harvesters and show the advantages of low cost and small volume. [9,15] Thus, many researchers have published papers about hybridization of the solar cells-TENGs or the solar cells-PENGs. [16][17][18][19][20][21][22][23][24] To sustainably generate energy from various energy sources, the solar cells were integrated with other types of energy harvesters, such as triboelectric wind energy harvesters or wearable triboelectric human-body energy harvesters. [25][26] Particularly, the tremendous efforts have been Nowadays, people can receive several types of information from portable and wearable devices. However, the limited working time period, rigid characteristic, and bulky size of the conventional power sources need to be improved for rocketing the compatibility with portable and wearable devices. In this paper, a flexible hybrid nanogenerator (FHNG) is presented by combining a solar cell, a transparent triboelectric nanogenerator (TENG), and a piezoelectric nanogenerator (PENG). The FHNG can sustainably collect energy from various energy sources. The FHNG can act as a self-powered wea...
