The thesis, presented by student Iman Mohsen Ahmed, focused on “Design and Simulation of High-Efficiency Quantum Dot Solar Cells Based on Nano-Crystal Technology.”
The thesis involved modeling GaAs solar cells with PIN configuration and quantum dot points using the Silvaco program. It explored the impact of adding nano-layers of InAsGaAs material in the middle layer of the solar cell on its efficiency.
Results revealed an increase in solar cell efficiency with the addition of several nano-layers, reaching 30% efficiency, a 60% improvement over the standard cell. The thesis also investigated the influence of elevated temperatures on cell performance, indicating a negative effect despite the presence of nano-layers, though less compared to standard cells.
