“…A significant increase in efficiency with the remaining diode characteristics fixed can be achieved either by increasing the photocurrent density or by decreasing the diode saturation current density (Fig. 4c, d) [20,21]. Thus, an increase in the photocurrent density by a factor of 1.1, from JPH  39.0 to JPH  43.1 mА/cm 2 , leads to an increase in efficiency up to 20.1 % (Table 1, Fig.…”

Possibilities of increasing the efficiency by more than 20 % for silicon photoelectric converters made in China have been investigated. It has been established by the method of computer simulation that the lifetimes of nonequilibrium charge carriers, which are 520 s, realized in such photoelectric converters, do not limit the possibility of increasing their efficiency by more than 20 %. It has been shown that an increase in the photocurrent density to 43.1 mA/cm 2 leads to an increase in the efficiency to 20.1 %, and a decrease in the diode saturation current density to 3.1•10 -14 A/cm 2 leads to an increase in the efficiency to 20.4 %. Simultaneous change of these diode characteristics leads to an increase in the efficiency to 23.1 %. The paper proposes physical and technological approaches to increase the photocurrent density and reduce the diode saturation current density in ready-made photovoltaic converters. The study of the influence of operating temperature on the efficiency of crystalline silicon photoelectric converters has been carried out in the article. It has been shown that with increasing operating temperature the relative decrease in the efficiency of single-crystal devices is -0.7 relative %/C, which is significantly higher than in the device structures of European production and due to non-traditional decrease in short-circuit current density. Mathematical modeling of the influence of light-emitting diode characteristics on the efficiency of crystalline silicon solar cells showed that a decrease in the efficiency of device structures with increasing operating temperature is due not only to an increase in diode saturation current density from 10 -13 to 3•10 -13 A, which is 300 %, but also by reducing the shunt resistance from 2.5 to 1.5 kOhm. A study of the effect of operating temperature on the diode saturation current showed that the height of the potential barrier in the studied silicon photovoltaic converters is 0.87 eV due to the insufficient level of doping of the base material. The limited height of the potential barrier leads to an unconventional decrease in the shunt resistance with increasing operating temperature.

“…However, these two parameters decrease with the alternating magnetic field. He also conducted a comparative study of the effect of the MF on the photocurrent of three types of PV cells (organic, dye-sensitized, and silicon solar cells) [16]. He found that the density of the photocurrent of the organic heterojunction cell increases with the increase of the MF whereas its impact on that of the dye-sensitized and silicon solar cells causes a decrease.…”

In earlier studies, we have shown theoretically and experimentally that magnetic fields (MFs) have negative impact on silicon PV module (photovoltaic module). A noticeable decline in photocurrent with a slight increase in photovoltage was observed. Also, how those fields affected other key module’s parameters was also studied. These studies concluded that an increase in the magnitude of the MF resulted in the decrease of the efficiency of the silicon PV module. The previous experimental studies assumed that the MF vector formed zero angle of inclination with respect to the photosensitive face of the module. They did not factor in any effect that could be observed when the field vector is inclined. The present experimental work is an attempt to fill that gap. The characteristic curves of the PV module were plotted in the same system of axis for different values of the inclination angle of the MF vector. Correspondingly, the characteristic values ( P max , I max , V max , I sc , and V oc ) of the PV module were also determined. These parameters then allowed the calculation of the efficiency of the module, its fill factor, and the equivalent circuit series and shunt resistances. It is observed that the module efficiency increases with the inclination of the MF vector, indicating that the effect of the MF on the PV module is reduced when its vector aligns towards a direction that is perpendicular to the base of the module. For example, when α moves from 0 to 90°, the power output and consequently the efficiency of the PV module relatively increase of 14%.

“…The effect of magnetic field on the photocurrent generation of organic solar cells, was investigated. In the case of bulk-heterojunction organic solar cell with the active layer made of P3HT:PCBM found that an increase of about 8% in the photocurrent density of the cell was observed when the intensity of the magnetic field reached 15mT, and moreover, the increase in the photocurrent density saturated at about 9% when the magnetic fled was further intensified [25]. Over 50% enhanced efficiency was observed from bulk heterojunction (BHJ) polymer solar cells (PSCs) incorporated with magnetic nanoparticles and an external magnetostatic field alignment when compared to the control BHJ PSCs.…”

<span>In this research, the effects of magnetic field intensity on electrical characteristics of a monocrystalline silicon solar cell were investigated. The experimental test-rig under Standard Test Condition was set up and tested to observe the respective effects. The electrical characteristics in terms of current-voltage-power curves, critical solar cell parameters and fill factor were then examined and analyzed. The outcome of this study demonstrates that the external magnetic field has a positive impact on electrical parameters, the experimental results showed that applying magnetic intensity of 60-260mT significantly affected the electrical characteristics of the cell; i.e., maximized cell current, voltage and power by 12.20, 7.12 and 23.60%, respectively. In addition, this positive impact consequencely happened on the i-v and p-v electrical characteristics curves of the solar cell; reflected by 3.69% increasing in the fill factor. </span>
