This thesis describes the development of a working thermal model of the Naval Postgraduate School's first CubeSat called NPS-SCAT and the accomplishment of environmental testing that has been completed to date in preparation for space launch. The primary mission of NPS-SCAT is to act as a Solar Cell Array Tester (SCAT), providing data on solar cell performance of various solar cells in Low Earth Orbit (LEO). As part of the satellite development process, a detailed test plan was developed and...

In this thesis, a new method for developing realistic simulation models of advanced solar cells is presented. Several electrical and optical properties of exotic materials, used in such designs, are researched and calculated. Additional software has been developed to facilitate and enhance the modeling process. Furthermore, specific models of an InGaP/GaAs and of an InGaP/GaAs/Ge multi-junction solar cells are prepared and are fully simulated. The major stages of the process are explained and...

This thesis investigates the potential use of wurtzite Indium Gallium Nitride as photovoltaic material. Silvaco Atlas was used to simulate a quad-junction solar cell. Each of the junctions was made up of Indium Gallium Nitride. The band gap of each junction was dependent on the composition percentage of Indium Nitride and Gallium Nitride within Indium Gallium Nitride. The findings of this research show that Indium Gallium Nitride is a promising semiconductor for solar cell use.

A quantitative, contact-free method for extracting minority carrier diffusion length is used to measure the relatively small variations in diffusion length associated with dislocation bands in mismatched epitaxy in the p-type region of a two dimensional heterostructure of a triple junction (InGaP/GaAs/Ge) solar cell sample. These measurements are taken using the line scan mode of a Scanning Electron Microscope coupled with an optical microscope. This technique allowed the variations in...

An optical, contact-free method for measuring minority carrier diffusion lengths is developed and demonstrated for a range of semiconductor materials used in high efficiency triple junction solar cells. This method uses a Scanning Electron Microscope (SEM) coupled with an optical microscope. The diffusion lengths, combined with minority carrier lifetime measured via time-resolved photoluminescence, allow for the computation of minority charge carrier mobility. The technique uses images to...

The Naval Postgraduate School Spacecraft Architecture and Technology Demonstration Satellite, NPSAT1, launching in the fall of 2006, will include a system to measure the performance of new experimental triplejunction solar cells. The measuring circuit in the Solar Cell Measurement System (SMS) is based on a circuit developed at the Naval Postgraduate School many years ago. It will trace the cells' current-voltage (I-V) curves while in orbit. The SMS consists of a radiation-hardened...

This document describes an experimental study conducted to examine the effects of protuberances on hypersonic boundary-layer transition. The experiment was conducted in the Langley 20-Inch Mach 6 Tunnel on a series of 0.9-scale Shuttle Orbiter models. The data were acquired to complement the existing ground-based boundary-layer transition database that was used to develop Version 1.0 of the boundary-layer transition RTF (return-to-flight) tool. The existing ground-based data were all acquired...

Degradation of solar cell performance from radiation damage was found to be reversed through annealing processes. The mechanisms behind the degradation and recovery is based on deep-level traps, or defects, in the lattice structure of the solar cell. Through a process known as Deep Level Transient Spectroscopy (DLTS) a correlation can be made between damage/recovery and trap energy level/concentration of the cell. Gallium arsenide (GaAs) and Indium phosphide (InP) solar cells were subjected to...

A need existed to perform high energy electron irradiation experiments on gallium arsenide solar cells. To support this research, an automated solar cell test facility was constructed, gallium arsenide solar cells were obtained, and the Naval Postgraduate School LINAC facility was utilized to irradiate the cells to selected fluence levels at 20 MEV energies. Equivalent damage coefficients were calculated, and it was found that the average maximum power output decreased by 50 % following a...

This thesis reports the results of a laser annealing technique used to remove defect sites from radiation damaged indium phosphide on silicon MOCVD grown solar cells. This involves the illumination of damaged solar cells with a continuous wave laser to produce a large forward-biased current. The InP/Si cells were irradiated with 1 MeV electrons to a given fluence, and tested for degradation. Light from an argon laser was used to illuminate four cells with an irradiance of 2.5 W/sq cm, producing...

Many improvements have been made in the design and manufacture of high efficiency solar cells. The need to understand the behavior of these new types of solar cells is crucial to the procurement of future space systems, both commercial and military. This thesis studies the results of irradiating three commonly used solar cells with 30 MeV electrons using the Naval Postgraduate School Linear Accelerator. A comparison of the performance characteristics of the three cells is made using commonly...

Test firings and launches will release air pollutants causing a temporary localized small degradation in air quality near the tests or launch site. Areas adjacent to the site will also be subjected to moderate sound levels of predominantly low frequencies for short durations. During the launch phase, hydrogen chloride will be introduced into the stratosphere causing a small decrease in ozone. Temporary perturbations to the ionosphere will occur during orbital maneuvers and entry will have no...

The minority carrier diffusion length is a critical parameter in the development of next generation Heterostructure Bipolar Transistors (HBT) and highly efficient solar cells. A novel technique has been developed utilizing direct imaging of electron/hole recombination via an optical microscope and a high sensitivity charge coupled device coupled to a scanning electron microscope to capture spatial information about the transport behavior (diffusion lengths/drift lengths) in luminescent solid...

The goal of this thesis is to explore the utility of in-situ optical imaging of charge transport imaging in multi junction solar cells. An in-situ measurement of a manufactured solar cell's key material parameters is difficult. Many sophisticated models may be used to predict performance of new cell arrangements and suggest next generation improvements. In parallel, an experimental view into a complex, multi layered, alloyed semiconductor device can provide important feedback for material...

The purpose of this thesis is to consider PhotoVoltaic Power Converter (PVPC) technology, developed by Atira Technologiesʼ, and its prospects for military and space applications. This research will validate the hypothesis that PVPC technology enables a solar power system to produce usable power during low- and no-light conditions which standard solar power systems fail to provide. Solar cell panels are exposed to sunlight at different angles and with variable intensity, therefore the...
