Background

Nada Benhaddou was awarded a PhD in thin-film solar cells with a chemistry background. She is currently a Research Associate working in PV Materials and Devices group at CREST (Centre for Renewable Energy Systems Technology). Her work includes various aspects of photovoltaic device optimisation and characterisation, with an emphasis on the development of solution-processed CIGS solar cells. She works on solar cells with a trade-off of improved conversion efficiencies and process reproducibility.

Main research interests

  • Development of photovoltaic solar cells using solution processing methods.
  • Interface engineering of the absorber/buffer interface.
  • Cd free solar cells architectures.
  • structural, composition and opto-electronic measurements of device performance.
  • Optical and electrical simulation of solar cells.
  • Fabrication of mini-module sized devices.
