The University of Nineveh discussed the master’s thesis on Tuesday, March 5, 2024, at the College of Electronics Engineering

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.

The examination committee comprised:

  1. Dr. Khaled Khalil Mohamed (Chairman)
  2. Assoc. Prof. Mohamed Tarek Yassin (Member)
  3. Assoc. Prof. Ahmed Mohamed Salama (Member)
  4. Dr. Qais Znun Najm (Member and Supervisor)
  5. Assoc. Prof. Omar Ibrahim Mohamed (Member and Supervisor).
