Latest Patents

Cloutier is named on 1 patent, titled “Doped Mixed Cation Perovskite Materials and Devices Exploiting Same.” The invention addresses a key challenge for perovskite devices: exposed films can degrade in ambient air, limiting their shelf life and complicating large-scale production.

The patent describes a thiocyanate-doped, three-cation material system designed to tailor perovskite grain size and microstructure, helping reduce degradation from atmospheric exposure. It also describes solvent-engineering techniques intended to support large-area processing and produce compact films with crystal grains larger than four micrometers and passivated grain boundaries.

Career Highlights

Cloutier’s patent work focuses on improving the stability and manufacturability of perovskite materials. These materials are of interest because they can offer strong photon absorption, useful carrier mobility, tunable band gaps, and solution-based processing at relatively low material cost.

Collaborations

The patent lists Ivy Mawusi Asuo and Dawit Minale Gedamu among Cloutier’s coworkers. Cloutier is associated with Socovar, Société en Commandite.

Conclusion

Sylvain Cloutier’s patented work explores ways to make perovskite films more durable and suitable for large-area device manufacturing, supporting their potential use in optoelectronic and photovoltaic technologies.
