Application Of Silicon Nanohair Textured P-N Junctions In A Photovoltaic Device, Michael Small
Application Of Silicon Nanohair Textured P-N Junctions In A Photovoltaic Device, Michael Small
Electronic Theses and Dissertations
The goal of this project is to design and develop a fabrication process for a silicon photovoltaic device which incorporates a nanohair textured p-n junction. The silicon nanowires are etched into a silicon wafer, comprising an epitaxial p-layer on n-substrate, via metal-assisted chemical etching (MACE). The resulting nanowires contain p-n junctions that lie along the length of the vertical nanowires. This construct has the potential to increase the optical bandwidth of a silicon photovoltaic device by allowing a greater amount of short wavelength light to reach the junction. In addition, the MACE method of nanofabrication has the potential for decreasing …

Transformerless High-Power Medium-Voltage Multi-Module Pv Converters, Hasan Bayat
Electronic Thesis and Dissertation Repository
This thesis is focused on the modular multilevel converter (MMC) for Photovoltaic (PV) applications. It is an attempt to address the issues associated with the modeling, control, and power mismatch elimination of the MMC-based PV systems. Firstly, a new real power reference generation scheme is proposed that creates a linear relationship between the real power reference of the system and the dc link voltage of the submodules. Further, a new power mismatch elimination strategy is proposed for the MMC-based PV system which ensures balanced currents are delivered to the host grid regardless of leg and arm power mismatches. The thesis …
The Analysis And Study Of Power System Designs For Same Polytechnic College In Tanzania, Kevin Lum Hua
The Analysis And Study Of Power System Designs For Same Polytechnic College In Tanzania, Kevin Lum Hua
Master's Theses
The Mbesese Initiative for Sustainable Development (MISD) is a group aiming to help eliminate extreme poverty in Africa by creating educational opportunity. One project that the group is currently doing is to build Same Polytechnic College (SPC) in Tanzania. As part of the project, this thesis aims to study and analyze the electrical power system and distribution for the college. Based on the projected load profile of the college and high potential for solar generation in Tanzania, several different power systems utilizing local utility AC electricity and/or photovoltaic (PV) DC electricity are explored and simulated for their feasibility and performance. …
Developing A 1-Megawatt Photovoltaic Power Plant For Liberty University, Andrew Knudsen
Developing A 1-Megawatt Photovoltaic Power Plant For Liberty University, Andrew Knudsen
Senior Honors Theses
A photovoltaic power plant with a generation capacity of 1-megawatt is designed for Liberty University. Liberty University’s location and size are stated to provide context for the design. Design choices are presented, first with general information that is applicable to any photovoltaic plant design, then with significant factors that impact this design. Specific models of solar panels and inverters are selected after the necessary classifications are determined. The final design has 2,880 solar panels with a fixed angle 30⁰ above the horizon, has two central inverters, and takes up 2.57 acres. Future research is suggested for finances as well as …
