Focus of this SBO project "PhyCIGS" is on:

• Understanding the physics of a Copper Indium Gallium Selenide (CIGS) photovoltaic (PV) stack, more specifically the electro-optical properties.
• Only studying CIGS and Transparent Conductive Oxide (TCO) layers.

Objectives of the project:

• Develop a baseline process for a CIGS solar cell stack to provide the SBO projects "absCIGS" and "weTCOat" with feedback about the performance.
• Build technological understanding, to allow an investment in cell integration capability: this should provide feedback to the ICON project "CIGStack".

Challenges are:

• Study and understand the interactions between the different layers and annealing conditions on the basis of printing technology for CIGS and TCO layers.
• Development of working cells to provide SBO projects "absCIGS" and "weTCOat" with feedback.
• Unravel the link between material synthesis, ink/paste formulations and post deposition treatment as to obtain the maximal efficient CIGS module and to understand the up scaling issues.
