Development Of Indium Arsenide Quantum Dot Solar Cells For High Conversion Efficiency, Mohamed El-Emawy
Electrical and Computer Engineering ETDs
Sunlight is the largest energy source available on earth. Under clear conditions there is approximately 1,000 watts per directly incident square meter, which reaches the earth everyday. Solar cells are devices that can be used to collect such abundant form of energy and convert it into electrical energy for daily consumption. Therefore, it is important to research this subject in order to obtain high efficiency solar cells. In this thesis InAs quantum dot (QD) solar cells are studied and investigated. The theory of using QDs as an intermediate band in GaAs-based solar cells is introduced. Three samples are grown for …
