Hybrid photovoltaic thermal (PV/T) solar system comprises a solar collector which is disposed on photovoltaic solar cells. The disadvantage of a conventional photovoltaic cell is that its performance decreases as the temperature increases. Indeed, part of the solar radiation is converted into electricity and is dissipated as heat, increasing the temperature of the photovoltaic cell with respect...

Heterogeneous photocatalysis offer many possibilities for finding appropiate environmentally friendly solutions for many of the the problems affecting our society (i.e., energy issues). Researchers are still looking for novel routes to prepare solid photocatalysts able to transform solar into chemical energy more efficiently. In many developing countries, biomass is a major energy source, but c...

Abstract. Lands mined for coal and reclaimed under the Surface Mining Control and Reclamation Act (SMCRA) can be used to produce woody biomass. This study evaluates woody biomass production on SMCRA-reclaimed lands after ripping to reduce soil compaction. Four species treatments were established at two planting densities on three Wise County, Virginia, mine sites. Here, we review experimental t...

This paper deals with the detailed of a hybrid model of a solar / wind in Simulink, which is using battery as its storage system. The simulation includes all realistic components of the system, in this system power delivered by the combine system component is compared with each other and various conclusions are drawn. A comparative study of hybrid model solar /wind system has been made. This pa...

ISSN: 2319-1112 /V3N1: 36-46 ©IJAEEE Abstract—Application with renewable energy sources such as solar cell array, wind turbines and diesel generator have increased significantly during the past decade. To obtain the clean energy, the hybrid solar–wind power generation is used. Consumers prefer quality of power from suppliers. The quality of power can be measured by using parameters such as volt...

As an inorganic photoabsorber, selenium was used in a mesoscopic solar cell with a hybrid organic-inorganic structure of TiO2/Se/P3HT/PEDOT:PSS/Ag, in which the Se layer was prepared by vacuum thermal deposition and post thermal treatment. The microstructure, photoelectrical properties, as well as the rationality in structural design of the solar cell were illustrated in detail. Finally, the hy...

We explored repurposing discarded materials to construct simple, field expedient, solar heating devices capable of heating drinking water to water pasteurization temperatures. Results of different test configurations quickly constructed from junk material indicate important design parameters to include maximizing exposed container surface area and using transparent glass and dark absorbent mate...

A hybrid solar panel has been invented to integrate photovoltaic (PV) cells onto a substrate through a functionally graded material (FGM) with water tubes cast inside, through which water serves as both heat sink and solar heat collector. Therefore, the efficiency of PV cells can be improved by temperature control while the heat conduction to the substrate can be minimized for saving of air con...
