Using Photovoltaic systems is gradually expanded by increasing energy demand. Abundance and availability of this energy, has turned to one of the most important sources of renewable energy. Unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). Second, the power produced b...

Chemical and crystallographic defects are a reality of solar grade silicon wafers and industrial production processes. Long overlooked, phosphorus as a dopant in silicon wafers is an excellent way to mitigate recombination associated with these defects. This paper details the connection between defect recombination and solar cell terminal characteristics, for one specific case of high hole life...

The power system utility has started to think about the green power technology in order to have an eco-friendly environment. The green power technology utilizes renewable energy sources for reduction of GHG emissions. Odisha state (India) is very rich in potential of renewable energy sources especially in solar energy (about 300 solar days), for installation of grid connected photovoltaic syste...

We present analytical simulations for the performance of nanocoaxial and -hemispherical drift-limited solar cells, to determine optimal geometrical configuration and to interpret results of experimental nanocoaxial solar cell arrays. The material system considered in these simulations is hydrogenated amorphous silicon (a-Si:H), with solar cells designed in an n–i–p stack. Simulations conducted ...

The shape of metallic nanoparticles used to enhance the performance of thin-film solar cells is described by Gielis' superformula and optimized by an evolutionary algorithm. As a result, we have found a lens-like nanoparticle capable of improving the short circuit current density to 19.93 mA/cm2. Compared with a two-scale nanospherical configuration recently reported to synthesize the merits of...

The space solar power station (SSPS) capable of providing earth with primary power has been researched for 50 years. The SSPS is a tremendous design involving optics, mechanics, electromagnetism, thermology, control, and other disciplines. This paper presents a novel design project for SSPS named OMEGA. The space segment of the proposed GEO-based SSPS is composed of four main parts, such as sph...

Photovoltaic string inverters with transformerless grid-connected architecture are the most commonly used solar converters owing to their appliance-friendly and cost-effective benefits. A novel circuit configuration for these is presented in this article, which seeks address shortcomings of conventional topologies such as problem leakage current, voltage ratio transformations, power quality. Th...

DANIEL BROSNAN: Comparison of Anatase Titania to Titanate Nanotubes in a Thin-Film Dye-Sensitized Solar Cell with Liquid and Solid Electrolyte (Under the direction of Professor Laurie McNeil) In this project, the properties of anatase titanium dioxide and titanate nanotubes were compared with respect to their function as a constituent material for the active layer of a dye-sensitized solar cell...
