“…Along with this, a promising direction of research is the study of temperature dependences of the parameters of solar cells [16][17][18]. Thus, in [15], the physics of the processes that determine the temperature sensitiv-ity of photovoltaic converters is discussed and the method of determining the temperature coefficients of the electrical parameters of nanowire solar cells (the open-circuit voltage UOC, short-circuit current density JSC, fill-factor FF, efficiency ) is presented.…”

“…The effect of temperature on the values of UOC, JSC, FF and  for Si-based nanowire solar cells is investigated by the authors of [18]. The typical character of the temperature dependences is obtained, but a decrease in the value of JSC with increasing temperature is observed, which may be associated with an increase in the effect of surface recombination of charge carriers.…”

The use of photovoltaic solar energy converters with nanowire solar cells is a promising direction for further development of photovoltaics. Along with this, significant interest in the properties of Si, InP, GaAs, InGaN nanowires as elements of high-efficiency photoconverters has formed a new direction of nanowire photovoltaics. The most relevant is the study of structural, optical, electrical, temperature and other characteristics of semiconductor nanowires. The paper presents the results of numerical simulation of coaxial p-in structures of solar cells based on Si and InP nanowires. The geometry of the 3D structures, light and dark current-voltage characteristics are designed using Silvaco TCAD tools. Within the framework of the drift-diffusion transport model with Fermi-Dirac statistics, the admissible values of the electrical parameters such as the open-circuit voltage UOC, short-circuit current density JSC, maximum power Pm, fill-factor FF, photovoltaic efficiency  and others are obtained. The temperature dependence of the current-voltage characteristics and electrical parameters is investigated. The temperature coefficients of the open-circuit voltage, short-circuit current density, fill-factor and efficiency for coaxial nanowire solar cells based on Si and InP are determined in the temperature range from 300 to 400 K. It is concluded that the thermal stability of the electrical parameters for InP-based photovoltaic converter is high, which is characteristic of direct band gap semiconductors. The obtained results of numerical simulation are in good agreement with the experimental data and can be used to predict the properties of nanowire solar cells.

“…Since sun rays fall non-perpendicular to the solar PV plant surface, solar energy entering the plant decreases, which is also due to its active area decrease, an increase in solar radiation losses in the protective coating of a solar PV array, and an increase in internal energy losses caused by individual solar PV plants shading. Papers [11,15,[18][19][20][21][22][23] prove this fact.…”

As a source of alternative energy, solar energy has apparent advantages, including a renewable, inexhaustible, and environmentally friendly resource. However, it has not become widely spread in the Russian Federation. Among the disadvantages of using solar energy are high equipment cost, low efficiency of photovoltaic solar cells, the generated electrical energy instability. The spatio-temporal variability of solar access causes electrical energy instability. It is possible to increase solar photovoltaic plant efficiency by using a tracking system to change the plant sun's spatial orientation. The paper offers mathematical and simulation models of a solar photovoltaic plant with a solar tracking system that allows the plant to be automatically oriented to the sun by matching the production mode and the solar access level. The use of the azimuth plant control system on the sun will increase the power production of the solar PV plant by an average of 28%. The same value will increase by 40% when using the full plant control system.

The optical spectra of structures with Ag nanoparticles between rough and cylindrical nanowires are calculated. The simulation was carried out using the finite-difference time-domain method (FDTD). As a source of radiation, a plane wave with the range of wavelengths 300–1000 nm is used. It is shown that with an increase in the root mean square (RMS) roughness of rough nanowires, the absorption coefficient decreases in the range of 500–750 nm due to an increase in the reflection effect. When silver nanoparticles are added, peaks appear at the wavelength of 840 nm (for cylindrical nanowires) and 900 nm (for rough nanowires), which indicates the manifestation of the surface plasmon resonance effect. It is shown that the electric field strength in a system with rough nanowires is higher than in a system with cylindrical nanowires.
