Missions

The use of flexible solar cells opens the way to new applications such as agriPV, sustainable mobility, the integration of solar panels into buildings (BIPV) and seasonal and nomadic photovoltaic solutions. The mission entrusted to the candidate is to develop lightweight, flexible, and highly efficient photovoltaic cells, with an efficiency of over 20%, using Cu(In,Ga)(S,Se)2 (CIGS) thin-film technology. However, the performance of a CIGS-based solar cell is highly dependent on the substrate used. In the case of flexible substrates, different aspects must be taken into account, such as adapting the deposition temperature to the substrate, adhesion of the layer, the addition of alkaline elements, and optimization of the absorber composition gradients. These are some of the aspects that the candidate has to look at as part of his research.

Activités

In order to develop flexible solar cells with high efficiency (>20%), the researcher will work mainly on the following aspects:
- adapting the absorber deposition temperature to the substrate used
- introducing alkaline elements
- controlling the composition gradients in the layer in order to obtain materials with the right optical and electrical properties
- adaptation of the back contact/CIGSe and CIGSe/front contact interfaces.
- monitoring and optimizing the performance of photovoltaic cells by identifying limiting factors. To this end, physicochemical characterizations of materials (GD-OES, DRX, Raman, PL, etc.) will be carried out and correlated with solar cell performance using basic tools, namely J(V) and quantum efficiency (QE), as well as more advanced analyses (J(V,T) and Q(E,V)).

Compétences

- You have a PhD in materials science, or a related field, and have extensive practical experience in the deposition and characterization of thin films using vacuum techniques. - You are well organized and motivated to take responsibility for a national project. - You are a team player and your strengths include taking personal responsibility, a strong desire for innovation, excellence, and the ability to work with several teams and achieve results. - You have excellent oral and written communication skills in English.

Contexte de travail

The project will be carried out at the IPVF (UMR 9006) (www.ipvf.fr).
