Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
This paper represent and assessment on solar power resource available in India. Day by day electrical energy consumption is increasing which also increases the generation of greenhouse gases due to uses of fossil fuel. The pollution level is crossing the danger limit, so world is moving towards practices of renewable energy sources. Solar energy is one of the largest and easily available renewable...
At the end of the solar module manufacturing process, an I–V measurement is performed under different illumination of each individual solar module to determine its current Imp and voltage Vmp at the maximum power point and the ISC and VOC points, where the power will be zero and the maximum value of power will occur between the two. The Fill Factor (FF) is essentially a measure of quality of the solar...
A High efficiency Solar Cell is reported using Quasi-mono-crystalline silicon (QMS) with nanovoids. It is used as the Semiconductor material. QMS of suitable dimension shows significant enhancement of optical absorptance which in turn provides higher efficiency of the solar cell. Properties of the QMS have been studied and compared with crystalline silicon. The absorptance of QMS at different wavelength...
This paper presents status of all branches of radial distribution networks in chronological order using distributed generation at optimal position by considering the concept of reactive loading index technique. Although under different situations for all the branches the identified weakest branch remains same up to some specified conditions but the corresponding loading at different branches in chronological...
In this paper, an attempt has been made to design optimally and evaluate the theoretical performance of a single solar cell (SSC) of glass-glass type photovoltaic (PV) Panel. In a modification, an in-built heat extraction mechanism has been made in the setup of solar cell in which the bottom side glass cover is cut up to certain depth to fill the metal more conductive than glass in such a manner that...
Conventional models for the Current-voltage characteristics of solar cells use numerical approach owing to the inherent mathematical intractability. Although the numerical models estimate almost accurate results, the computational cost and time needed for these models is huge. These models also lack of physical insight. An analytical model is, therefore, necessary to resolve these issues. Based on...
The increasing deployment of photovoltaic (PV) systems requires large numbers of skilled engineers with a greater understanding of all aspects of PV technology both theoretical and practical. Developing experimental rigs at universities is expensive and limited to students physically attending the university. One recent approach to increase access to laboratories is the development of remote experiments...
The utilization of the water vapor adsorption - condensation - evaporation - desorption cycle with porous thermoresponsive materials for passive solar cooling is analyzed. The recent work in the development, characterization and interaction of solar irradiation with micro- and meso-porous composites of high water vapor adsorption capacity in a wind tunnel of adjustable environmental parameters is...
We report the effect of boron doping on optical and electrical properties of p-type a-Si∶H films. The p-type a-Si∶H thin films have been deposited by RF-PECVD system varying the diborane flow rate from 5 sccm to 9 sccm. Enhancement in deposition rate from 30.3 nm/min to 33.6 nm reported with increasing diborane gas flow rate. Change in band gap, refractive index and Urbach energy with varying doping...
Natural dye sensitized solar cells (DSSC) have been widely investigated as a next generation solar cell because of their simple structure and low manufacturing cost. In the present work betacyanin dye responsible for the red color of many fruits and leaves having favorable absorption spectra with the solar spectrum has been used in fabrication of solid state dye sensitized solar cell. A Nanocomposite...
There is rapid growth in demand for air conditioning due to rising population and economic development. This technology should diversify and utilize alternative source of energy like solar energy for sustainable development. Liquid desiccant based air conditioning system (LDAC) is adaptable to solar thermal energy and has advantages like high density energy storage and low regeneration temperature...
The paper depicts generation of solar power by the charge controller skills to charge the battery bank at a persnickety voltage during the sunbeams by the Flyback converter to make use of this power at spacecraft power systems during the orbital night or when the load demand goes beyond the solar booth or array capacity. All bits and pieces are supervised by the Flyback power supply entity as light...
The photovoltaic source exhibits non linear V–I characteristics which depends on solar insolation and environment factors. The development of accurate circuit oriented model is essential to simulate. The equivalent circuit configuration of photovoltaic cells of solar system are discussed here considering environmental factors and their V–I characteristics are plotted. Also their performance for achieving...
Scarcity of conventional energy makes world feel the urge of alternatives that is non-conventional source of energy. In this paper, we propose a technique to efficiently store solar-energy by introducing Enhanced-Super-Capacitors (ESCs). A new technology, the super capacitor, has emerged with the potential to enable major advancement in energy storage. Super capacitors are governed by the same fundamental...
Emergency situations like natural calamities generally disrupt power supply, which hinders the relief and rehabilitation operations. Post disaster, one of the most immediate and important need is to setup a communications network, which is not feasible by conventional means. This paper describes the design of working prototype of a totally self-contained and easily re-locatable system, which can provide...
There are many places in our earth which is unknown and undiscovered for human beings. But nowadays capable and adaptable robots can explore areas too dangerous or costly for humans to visit. Using this robot with Hyperspectral Image Processing we can explore the geological structure of that place, minerals containing and other geographical data. For the movement of the robot we need energy and here...
