“…In contrast to the laser modification after chemical treatment (sample #2, Figure 2 b), the resulting structure was a randomly arranged pyramid with a base width of 1 to 5 μm. The side faces did not have visible irregularities, and their orientation was parallel to the crystallographic planes 〈111〉 [ 35 ].…”

Light-trapping structures formed on surfaces of various materials have attracted much attention in recent years due to their important role in many applications of science and technology. This article discusses various methods for manufacturing light-trapping “black” silicon, namely laser, chemical and hybrid chemical/laser ones. In addition to the widely explored laser texturing and chemical etching methods, we develop a hybrid chemical/laser texturing method, consisting in laser post-texturing of pyramidal structures obtained after chemical etching. After laser treatments the surface morphology was represented by a chaotic relief of microcones, while after chemical treatment it acquired a chaotic pyramidal relief. Moreover, laser texturing of preliminarily chemically microtextured silicon wafers is shown to take five-fold less time compared to bare flat silicon. In this case, the chemically/laser-treated samples exhibit average total reflectance in the spectral range of 250–1100 nm lower by 7–10% than after the purely chemical treatment.

“…At the same time, the actual achieved efficiency of solar cells, which has significantly increased from 11 to 15 % for those previously created on the basis of silicon and germanium, currently does not exceed 39 -41 %, even for a new generation of photovoltaic semiconductor converters. They are developed on the basis of multilayer, for example, AlInGaPAs/GaAs/Si, InGaP, InGaAs and Ge nanoheterostructures of cascade type grown by gas-phase epitaxy from organometallic compounds on silicon and germanium substrates [98][99][100][101][102][103][104][105][106]. At the same time, an increase in the maximum power of the solar cells is achieved not only by improving the structure of p-n junctions, but also by focusing the sun's rays using mirrors and Fresnel mini-lenses.…”

In this paper, the achievements, problems and prospects of creating personalized energy systems based on nanostructured materials are analysed. Various concepts of developing methods and ways of personalized energy provision for autonomous human survival in remote natural habitat, emergency situations of natural disasters and technogenic catastrophes when centralized power supply is unavailable or in an effort to reduce the economic and environmental costs of remote energy production and transportation are also considered. The possibilities and limitations of using traditional and renewable alternative energy sources, processes and devices for extracting, storing and converting their energy into the necessary consumer forms due to fundamental physical laws are discussed as well. The article covers the new nanostructured materials with special functional properties for personalized energy systems development. The mechanisms for formation of the required nanostructures in synthesized materials, especially those with a high content of fractal interfacial formations, are considered as well as methods for studying their structural and phase characteristics that determine the achievability of the specified parameters of model converters and energy storage devices.

“…They show that the variability of electricity generation from renewable energy sources (RES) can be counterbalanced by storing excess energy. Other studies have also been devoted to finding the optimal combination of wind and solar energy for different regions and using data covering different periods [8][9][10], and studies usually show that the inclusion of several types of RES reduces the volatility in electricity generation, reducing the need for reserves [11,12].…”

Study of the joint daily variability of wind speed and solar activity in the region of Gulf of Finland and its impact on renewable energy sources. The influence of external factors on the variability of total output power of ground-based wind turbines and solar photovoltaic panels is investigated. To a small extent, wind turbines are able to complement the generation of renewable energy sources: 15% –30% wind turbines and 70% –85% solar photovoltaics is preferable ratio of renewable energy sources. Comparing two similar climate regions in different scenarios lead economic feasibility strongly corelate with fuel prices. Standalone diesel generators can be quite effective at first, but in the long-term it is not viable solution due to fuel costs. Combined wind-PV renewable energy system is more profitable, but it has higher initial cost.
