A Study of Solar Radiation, Storage and Applications in Nigeria

Odia O.O., Ambrose Alli University, Ekpoma, Edo State, NG

The paper investigates the availability of solar energy in Auchi, a town in Nigeria located between longitude 6o15’ East of the GM line and latitude 7o02’ North of the Equator using photovoltaic solar cells and [...]

Ionic Liquids as Heat Transfer Medium

Schubert T.J.S., Sahin H., Beyersdorff T., Iolitec - Ionic Liquids Technologies GmbH, DE

Based on our investigations we will report an overview about thermally stable ILs. By pre-selecting a comprehensive matrix of different anions and cations from our substance library of more than 600 compounds, using known physical [...]

Ultrasonic Spraying of Carbon Nanotubes using NMP

Willey A., Davis R., Vanfleet R., Brigham Young University, US

We will present a new method for spraying thin films of carbon nanotubes, in which they are suspended in an organic solvent and then sprayed ultrasonically onto a heated substrate. These thin films have applications [...]

The role of cetyltrimethylammonium bromide in efficiency of organic-quantum dot hybrid solar cell

Heo S.J., Yoon S., Oh S.H., Kim H.-J., Yonsei University, KR

We fabricated high efficiency organic-quantum dot hybrid solar cells. By employing the hybrid active layer, which absorbed the light in wide range, the short circuit current (Jsc) is increased due to a multiple exciton generation [...]

Thermal Stability of Nano-Structured Selective Emitters for Thermo Photovoltaic

Lee H.J., Bathurst S.P., Kim S-G, Massachusetts Institute of Technology, US

This study aims to provide the high temperature stability of tungsten selective emitters for thermophotovoltaic (TPV) systems. Photonic crystals have periodic nano-structures that are designed to control the motion of photons at certain wavelengths, giving [...]

Enhancement of photoelectrochemical and optical characteristics using a TiO2 nanoparticles interlayer in MEH-PPV heterojunction devices

Habelhames F., Girtan M., Manole A., Lamiri L., Zerguine W., Nessark B., Univesité Ferhat Abbas, DZ

In this work, MEH-PPV+TiO2 composite material was prepared by incorporation of titanium oxide nonoparticles (TiO2) into poly[2-methoxy-5-(2’-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) polymer matrix and deposited by spin coating on glass and indium thin oxide (ITO) substrates. The absorbance [...]

Optimizing Quantum Well Solar Cell Efficiency through Genetic Algorithms

Pacheco M.A., Pontifical Catholic University, Rio de Janeiro, BR

In this work, a study of quantum well solar cells (QWSCs) is carried through. The use of quantum wells was pointed as a tool to increase the efficiency of photovoltaic. The objective is to describe [...]

Copper nanowires on Recycled Conducting Glass for DSSC Electrodes

Liao C-Y, National Cheng Kung University, TW

A simple method for recovery of ITO glass from thin film transistor liquid crystal display (TFT-LCD) wastes for dye-sensitized solar cell (DSSC) electrodes has been developed. The ITO glass separated from the color filter and [...]

Micro-CSP Grid Integration

Kimura D.T., Sopogy, US

Sopogy’s MicroCSP power generation systems provide stable electricity for the grid. Instead of using batteries or grid consumption as back-up, MicroCSP relies on low cost thermal storage. Sopogy’s micro-concentrated solar power technology, MicroCSP, launched in [...]

Quantum Dot Enhanced Rugate Filtering and Light Trapping

Shepard S., Copeland J., Louisiana Tech University, US

Rugate filters use an exponential sinusoidal index profile, which is also multiplied by a window function to further reduce side lobes in comparison to other (discrete index) interference filters. These also have negligible harmonics and [...]
