Introduction: Accessibility to safe drinking water is an important human health issue, so water reuse and water resources management are critical in arid parts of developing  regions. This study aimed to investigate the use of a combined simple designed solar geyser/photocell for drinking water disinfection. Materials and Methods: In this study, a solar geyser with a simple design was combined...

Developing specialized software tools is essential to support studies of solar activity evolution. With new space missions such as Solar Dynamics Observatory (SDO), solar images are being produced in unprecedented volumes. To capitalize on that huge data availability, the scientific community needs a new generation of software tools for automatic and efficient data processing. In this paper a p...

A low temperature (<100 °C), flexible solar cell based on an organic-inorganic hybrid CH3NH3PbI3 perovskite-fullerene planar heterojunction (PHJ) is successfully demonstrated. In this manuscript, we study the effects of energy level offset between a solar absorber (organic-inorganic hybrid CH3NH3PbI3 perovskite) and the selective contact materials on the photovoltaic behaviors of the planar org...

Construction of ordered electron acceptors is a feasible way to solve the issue of phase separation in polymer solar cells by using vertically-aligned ZnO nanorod arrays (NRAs). However, the inert charge transfer between conducting polymer and ZnO limits the performance enhancement of this type of hybrid solar cells. In this work, a fullerene derivative named C60 pyrrolidine tris-acid is used t...

A hybrid photovoltaic/photoelectrochemical (PV/PEC) water-splitting device with a benchmark solar-to-hydrogen conversion efficiency of 5.2% under simulated air mass (AM) 1.5 illumination is reported. This cell consists of a gradient-doped tungsten-bismuth vanadate (W:BiVO4 ) photoanode and a thin-film silicon solar cell. The improvement with respect to an earlier cell that also used gradient-do...

Effective utilization of power is more important than generation of power because power scarcity is the major problem at present in India. It leads many industries to utilize the diesel generator results pollution and demand to fossil fuel. So nowadays many industries and government passions on renewable energy. A wind solar hybrid power system plays a crucial role today in renewable power reso...

Joglekar, Chinmay S. M.S.Ch.E., Purdue University, May 2014. CZTSSe Thin Film Solar Cells: Surface Treatments. Major Professor: Rakesh Agrawal. Chalcopyrite semiconducting materials, specifically CZTS, are a promising alternative to traditional silicon solar cell technology. Because of the high absorption coefficient; films of the order of 1 μm thickness are sufficient for the fabrication of so...

A key consideration for the efficient operation of hybrid solar cells based upon conjugated polymers and inorganic semiconductor nanocrystals is charge transport in the nanocrystal phase. Here we report the results of a study into the charge transport kinetics of polymer/nanocrystal solar cells based on blends poly(3-hexylthiophene) (P3HT) with either CdSe nano-dots or CdSe nano-tetrapods. Tran...

In Environmental friendly solutions are becoming more eminent than ever as a result of concern regarding the state of our worsen planet. This paper presents a modeling of solar and fuel cell hybrid isolated full bridge converter for electric vehicle driving system. The HFT (high frequency transformer) initiate in isolated full bridge boost converter for precipitate power conversion of photo vol...

Now a day‟s electricity is most needed facility for the human being. All the conventional energy resources are depleting day by day. So we have to shift from conventional to non-conventional energy resources. In this the combination of two energy resources is takes place i.e. wind and solar energy. This process reviles the sustainable energy resources without damaging the nature. Renewable ener...
