What will you be doing?

We are looking for an intern within the unit Industry in which our inspirational work is geared to technological breakthroughs to create innovations in key societal and economic themes. Our projects tend to have a significant international impact and our facilities are unique.

Long lifetimes of solar cells are a prerequisite for large-scale implementation and application of solar energy. In thin film solar cells the transparent conductive oxide (TCO) plays an important role as it serves as the upper electrical contact in the cell. The TCO layer should stay transparent over a large spectral window and maintain its high conductivity during many years of operation. In outside conditions the combination of heat and moisture, however, can cause degradation of the TCO.
In this project, the changes that occur at (and near) the glass TCO interface will be studied. The identification of degradation mechanisms should lead to ideas for new materials or process parameters that enhance the lifetime of the TCO. A unique experimental set-up will be used that allows to follow chemical reactions and structural changes in-situ by X-ray diffraction under operation conditions i.e. heat, humidity and electric fields.

The research will take place at TNO Solliance at the High Tech Campus in Eindhoven.

What do we require of you?

  • Background in (technical) chemistry or physics or electrical engineering.
  • Interest in renewable energy.
  • Highly motivated and have an accurate and critical work attitude.
  • Able to work relatively independently within a small team.
  • The duration of this project should be minimal six months, preferably in the MSc phase of your study.
