“…Both of these two solar energy generation technologies are suitable for various character buildings on roofs, building facades and wall coverage. The different sorts of BIPV have been analyzed by Vasilliev [8], the energy harvesting efficiency, influence on city and building and the system aesthetics of non-transparent PV and transparency PV have been discussed. In community scale, more attentions have been relayed on the building cluster design reflecting on improving energy efficiency.…”

The increasing demands of renewable energy lead to upgrading and iterating on current centralized grid system. Depends on the unique characteristics of green energies, such as photovoltaic power, wind power and so forth, the wide range of geographical allocation, power uncertainty and near to end-users has become the crucial consideration factors for next era energy system. Distributed energy system (DES) as a new emerging energy management method, it shows large numbers of similarities with renewable energy and it has been deemed as a potential reasonable way to solve the above issues. In order to illustrate whether DES have the ability to provide citizen with a sustainable, reliable and efficient grid system, this paper try to evaluate it from DES applications in different scopes and possible supportive energy internet technologies. Through discussing DES in regional and community scale, the physical limitations have been pointed out. Furthermore, micro-grid, blockchain technology and Virtual Power Plant (VPP) has been elected as potential methods to solve DES existing problems, such as data loads, inter communications between energy provider and consumer and energy trading mechanism. Since DES could not reach the optimal working status without other technologies support, how to integrate and combine different new emerging technologies into this energy system could be a further research direction. This significance of this paper is evaluating possibility of creating an autonomous, reliable, highly efficient and tradable energy system based on DES.

“…In this study, we have proposed silicon and chalcogenide upon fused silica‐based embedded optical waveguides 14 for visual and infrared (IR) photon concentration. An increase in photon quantity can enhance the efficiency of the hybrid solar cells by producing more electrons, which will subsequently increase electric power generation capability 15 .…”

Solar energy is pollution‐free with less impact on the ecosystem, but it has limitations due to its intermittent nature attributed to sun availability for specific hours, resulting in less energy conservation efficiency. Similar to the purpose of carvings on the leaves to collect water, we are presenting a nanometer‐thick layer of silicon or chalcogenide with fused silica for photons enhancement in red and the blue portion of the spectrum within the solar energy reaching the earth's surface. The design is based on nanorod imprints on micrometer‐sized conventional fused silica, ensuring better absorption and transportation toward hybrid photovoltaic cells. Hybrid solar cells (comprising silicon and perovskites) are typically termed the future of solar power, but will not be discussed here. Effective area, optical power concentration, and second‐ and higher‐order dispersions can further help design and develop the photon concentrators.

“…Energy demands are multiplying as the technology evolves without any boundary limits in the modern era. The demand in the energy sector is forecasted to rise by 56% from 2010 to 2050, which certainly will increase the pollution factor due to carbon dioxide emissions [1]. PV energy is a type of renewable energy that has several advantages compared to other renewable energy sources.…”

In this paper, a stand-alone photovoltaic (PV) system based on a Double Ended Forward Converter (DEFC) is presented. The proposed converter is specified for 48 V, 100 W applications as most of the equipment used in telecommunication and aircraft fall in this range. The literature has limited potential application of DEFC in PV systems. The research work deals with an in-depth study of DEFC and proposes an improved DEFC for PV applications with battery backup. Besides, a bi-directional dc-dc converter for the battery is integrated to track the Maximum Power Point (MPP) of the PV generator. The converter is examined under variable irradiance and load conditions, and the analytical analysis of boundary conditions are implemented. The converter's architecture also ensures built-in I-V curve tracing for the identification of MPP of PV generator. It offers low voltage stresses across switches and avoids sinking power supply and core resetting circuits. The topology's behavior is analyzed based on MPP achievement and maintaining output under different conditions of battery backup availability, environmental, and load conditions. The PV system architecture is designed and analyzed theoretically and verified with simulations on the PSIM software.
