“…However, Solar Cell characteristics are non-linear and depend on environmental factors such as irradiation and temperature [1]. Power converters are usually employed to connect the PV array to the load in order to match the load characteristics [2]. However, these power converters before practical implementation are to be tested for all kinds of faults, grid disturbances and reliability.…”

This paper proposes a near accurate Solar PV Emulator using DC-DC Buck converter. A mathematical model serving as a reference is built using MATLAB/SIMULINK for emulating Solar PV characteristics. In the proposed Emulator by changing model parameter values it is possible to emulate any Solar PV characteristics. Hardware implementation is done using dSPACE ds1104 controller board and a closed loop control system is built using PI controller. The proposed Emulator has the following characteristics: 1. Fast and accurate Solar PV Emulator with easy interfacing and real-time control 2. Features to extend the system for other Solar PV panels 3. DC-DC Buck converter having high bandwidth. 4. Faster dynamic response and highly stable output with lower response time. 5. Lower output voltage and current ripple. Experimentations are done under different operating conditions and the results obtained are compared with the existing Emulators.

“…Earlier studies have corroborated the statement that renewable sources of energy are essential for mitigating climate change, in particular when implementing the Kyoto Protocol and 'green credits' trading. Renewable sources can be used in the electric energy sector and as environment-friendly vehicle biofuels (Jäger-Waldau 2007;Li et al 2018), as well as in space exploration (Komerath et al 2011;Pisacane et al 2005).…”

The paper overviews Russian and foreign studies on renewable energy. In view of some economic and environmental premises, namely depletion of the traditional energy sources and growing costs of their exploitation, a new alley is being paved in scientific literature and global practices for displacing traditional energy resources and providing for a substantial contribution of renewable sources to total energy consumption. In this context, the aim of this study is to determine what role renewable energy will play in the socio-economic security of territories, to identify the potential and possible applications of renewable energy. The main tasks for the study were to: identify the socio-economic implications of the transition from traditional to renewable energy sources, study the foreign experience of implementing renewable energy policies, estimate the potential and evaluate the prospects for renewable energy with the focus on rural northern regions. The potential for renewable energy market growth in Russia was estimated, specifically for the Northwestern macroregion. To provide for socio-economic security, the energy policy being developed must have an environmental and economic orientation. Primary focus in the development of renewable energy sources should be on peripheral regions, which have no electrical grids of their own and are energy deficient.

Heteroatom-doped graphene and its application as a counter electrode in dye-sensitized solar cells

Summary The most frequently used counter electrode (CE) in dye‐sensitized solar cells (DSSCs) is platinum on fluorine‐doped tin oxide glass. This electrode has excellent electrical conductivity, chemical stability, and high electrocatalytic affinity for the reduction of triiodide. However, the high cost of metallic platinum and the poor electrochemical stability pose a major drawback in the commercial production. This has necessitated a search for a non‐precious metal and metal‐free electrocatalyst that demonstrates better catalytic activity and longer electrochemical stability for practical use in DSSCs. Graphene has been at the centre of attention due to its excellent optoelectronic properties. However, a defect‐free graphene sheet is not suitable as a CE in DSSCs, because of its neutral polarity which often restricts efficient charge transfer at the graphene/liquid interface, irrespective of the high in‐plane charge mobility. Hence, heteroatom‐doped graphene‐based CEs are being developed with the aim to balance electrical conductivity for efficient charge transfer and charge polarization for enhanced reduction activity of redox couples simultaneously. The elements commonly used in chemical doping of graphene are nitrogen, oxygen, boron, sulfur, and phosphorus. Halogens have also recently shown great promise. It has been demonstrated that edge‐selective heteroatom‐doping of graphene imparts both efficient in‐plane charge transfers and polarity, thereby enhancing electrocatalytic activity. Thus, heteroatom‐doped graphene serves as a good material to replace conventional electrodes and enhance power conversion efficiency in DSSCs. The focus is to reduce the cost of DSSCs. This review explores the performance of DSSCs, factors that influence the power conversion efficiency, and various physicochemical properties of graphene. It further outlines current progress on the synthetic approaches for chemical doping (substitutional and surface transfer doping) of graphene and graphene oxide with different heteroatoms in order to fine‐tune the electronic properties. The use of heteroatom‐doped graphene as a CE in DSSCs and how it improves the photovoltaic performance of cells is discussed.
