Projet AxLR « Highly stable pervoskite solar cells »

TENDER DESCRIPTION

The innovation developed within the IEM laboratory in Montpellier consists of stabilizing perovskite materials. The researcher behind this discovery demonstrated that a stable perovskite ink formulation could be implemented for the production of photovoltaic panels. The advantage of perovskites in photovoltaics is that the material allows absorbing additional wavelengths beyond what silicon materials can achieve. However, a major drawback limits the deployment of perovskites in solar energy today; the materials are very sensitive to light, humidity, and heat. The innovative formulation offers a promising solution as preliminary results estimate stability beyond 25 years. If these results were demonstrated by measurements according to current standards, the perovskite photovoltaic market could finally develop and compete with silicon photovoltaics. The AxLR maturation proposes a technology development program to demonstrate performance on representative photovoltaic modules. The contract aims: - On the one hand, the production of small-area photovoltaic cells on glass substrate, with the objective of high power conversion efficiency according to solution-processing techniques…
