The SBO project "absCIGS" features research along two tracks: the CIGS-track and the OPV-track:

• CIGS: Copper Indium Gallium Selenide
• OPV: Organic PhotoVoltaic

The CIGS-track has two high-level research aims:

• Developing a lab-scale non-vacuum baseline process for the formation of CIGS absorber layers leading to cells with conversion efficiency of 15%
• Build up scientific understanding of the different steps in the process, from the formation of the CIGS precursors to the film transformation process

Challenges for this track are:

• Creating a well-defined starting point: fully characterized nanoparticle colloids
• Unravelling the magic: input-output relations in film transformation
• Understanding what is happening: develop and implement models that describe nanoparticle film transformation

The OPV-track has the following objectives:

• Incorporation of nanoparticles in the OPV bulk heterojunction to widen absorption window
• Reviewed to include other approaches with higher prospectis of improving efficiency

Challenges:

• Incorporation of nanoparticles in the organic matrix
• Interaction between the molecular additives and the organic matrix
