For generating electric power through the energy received from the Sun, solar PVS is an emerging technology. It is playing a key role to consume solar energy as much as possible. Electric power is generated by the PV array in form of DC. This DC power before utilization for domestic or industrial uses must be converted into AC. If the PVS is grid-connected then the inverter requires high efficiency, maximum power point tracking, total harmonic distortion of currents injected into the grid must have low and the power injected into the grid must be controlled. The employed control schemes decide the performance of the inverter which is connected to the grid. In this paper, all aspects related to grid-connected inverter are presented that includes historical evolution of the inverter topologies, standards and specifications, summary of inverter types, and classification of inverter topologies. Also, a discussion has been presented based on the number of power processing stages required in the system to fed electrical power into the grid.

The increasing dependence on electrical power and uneven distribution of energy reserves needs suitable converter design to meet low demand efficiently. MLIs have reduced harmonics and are best suited for domestic as well as industrial applications. With the current improvements in renewable energy systems (RES), uses of traditional MLI topologies are thwarted because of their issues in performance like low power quality, low efficiency, and uneconomical structure. These confinements in the performance issues of traditional MLI topologies have pulled in the researchers toward developing new hybrid type of MLI topologies. In the present article, a detailed analysis of such current hybrid MLI topologies is given based on certain indices covering both qualitative and quantitative performance. Due concentration has been given to widely review the impact of MLIs in grid associated renewable energy applications, for example, photovoltaic (PV) frameworks, wind energy conversion systems (WECS) as well as microgrids.

Presented power storage unit (PSU) and RPC, such as fuel cell, is based on oxygen reduction reaction (ORR). Such PSUs are associated with poor kinetic ORR and oxygen evolution reaction (OER) limitations. Stable and dynamic catalysts like single atom catalysts, metal-free carbon materials and nanocomposites has renovated its applications in RPC. Recent development of bifunctional catalysts (BFC) and metal organic frameworks (MOFs) for both OER and ORR has improved the stability of MABs. For the development of BFCs strategies being carried out includes micro-nano design (e.g., chemical vapor deposition, electrochemical methods, template methods and hydrothermal methods), fabrication of new materials (composite materials, transition-metal materials, and carbon), and material property alteration (oxygen defects, heteroatom doping, interfacial strain, adjustments of electronic structures, nano composites, metal–oxygen bonds, etc.). For the fabrication of MOFs, aqueous and non-aqueous electrolytes are being developed. This paper deals with brief discussion of MABs for active and stable application in PSUs and RPCs.

The utilization of RES for the generation of electricity is increasingly gaining interest of researchers during the last decades. The main reason behind this is global incentivization, the increasing price of petroleum products, climate issues and deregulations in the energy market. As the Government of India, (MNRE i.e. Ministry of New & Renewable Energy) is targeting to generate 20000 MW power through grid-connected solar PVS by the year 2022 therefore, the main focus in this paper has been presented on power generation through grid-connected PVS. The emerging smart grid technology has enabled the grid-connected PVS as an evolving process in today’s world for electrical power generation. However, apart from so many advantages, there are several issues and challenges associated with the integration of PVS to the electric utility grid hence, the investigation to find out available po...

To overcome the consequences on global warming due to fossil fuel-based power generation, PV cell technology came out as an emerging and sustainable source of energy. A renewed assessment regarding the performance of this emerging technology is essentially required for the recent developments and to analyze their potential in forthcoming applications. The developments of various PV cells can be classified in to four primary groups, known as generations. However, the first two generations are mainly responsible till date for the commercialization of solar PV cells in the entire market. The efforts have been made in this approach to appraise the progress of each technology in the near future by presenting a comprehensive comparative study of PV cell parameters for all generation technologies. Additionally, the fourth-generation technology has been especially focused in this work in which the distinct roles of organic and nano-components is presented.
