Comparative Study Between Gallium Arsenide and Standard Silicon Solar Cells On Spacecraft and Terrestrial Applications
Mahmoud Mustafa Muhammad Mahmoud;
Abstract
This thesis discusses the most important topic in the energy field which Egypt needs nowadays, Egypt is one of the major regions in the world blessed by God with high solar irradiance, and as many studies have revealed that with the present rate of usage, all fossil fuel resources will be practically depleted within few decades thereby stressing the need to develop cheaper sources of renewable energy with high efficiency among which solar cells should play an important role.This thesis is divided into five chapters and an appendix.
Chapter One: This chapter discusses short introduction about solar cells.
Chapter Two: This chapter discusses basic parameters of solar cell, solar cell made materials, examples of terrestrial & space applications .
Chapter Three: This chapter discusses short introduction about the GaAs and Silicon used in solar cells, Two approaches are applied, photovoltaic system (PV) without tracking system (Fixed System) and PV with manual tracking systems to show the differences between using Si and GaAs solar cells. The study take place through different factors.
Chapter Four: In this chapter, we calculate the orbital elements due to solar radiation pressure on Silicon and GaAs solar cells . There are many perturbations that affect on a satellites which may deviate from their designed paths which tend to change their orbital elements. Such perturbations are gravitational and non gravitational.The actual position and velocity components of satellites are calculated at any instant of time. Hence calculating the actual orbital elements which are affected by perturbations (Oblateness of Earth, Atmospheric drag, Solar radiation pressure.. This leads to dominate the perturbation of altitudes for LEO and MEO; The Result shows that the effect of Solar Radiation Pressure on silicon solar cell is greater than on GaAs solar cell .
Chapter Five : This chapter concludes the study and suggests work after this research.
Appendix and References : Extra material and references for this thesis.
