Thermal Stability of Nano-Structured Selective Emitters for Thermo Photovoltaic
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
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
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
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
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 [...]
Characterization of Solar Grade Silicon Contaminants
The term ‘Solar Grade Silicon (SoG)’ has been used for many years but until recently, there were no specifications as to what this actually meant. Without specifications, suppliers of silicon have been using ‘number of [...]
Improvement of Silicon Solar Cell Metallization with Printed Metal Nanoparticle Inks
The process and quality of metallization greatly affects the performance and cost of solar cells. Screen printing of silver paste and fire-through of the silicon nitride antireflection layer is the most widely used method for [...]
Quantum Dot Enhanced Rugate Filtering and Light Trapping
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 [...]
