P-layer

P-layer SAS, founded in 2016, is a deep-tech company focused on developing a novel smart-glazing technology. The firm was established by Andrés G. Reyes-Lega, who holds a Ph.D. in mathematical physics, and Jean-Louis de Bougrenet de la Tocnaye, a professor and head of the optics department at IMT Atlantique with extensive research in liquid crystals and optical processing. The company's core innovation originates from research conducted at the ICube laboratory, a joint research unit involving CNRS, the University of Strasbourg, and others, in collaboration with the University of Southampton.

P-layer's patented technology centers on the integration of semiconductors and liquid crystals to create materials that can modulate light and potentially generate electricity. This composite material allows for the dynamic control of transparency and heat, offering a solution for energy efficiency in various sectors. The business targets applications in architectural glazing for buildings, transportation, agricultural greenhouses, and sensor protection. By adjusting the light and heat transmission, the technology aims to reduce the energy consumption required for heating and cooling.

The company's business model revolves around the commercialization of this unique technology, likely through partnerships with glass manufacturers and industrial clients in its target markets. P-layer aims to provide a versatile material that can be customized for specific uses, from improving building insulation to protecting sensitive optical equipment. The technology's ability to switch between transparent, opaque, and intermediate states gives it a functional advantage for creating adaptive environments and surfaces. As of June 2016, William Engelmann serves as the President of the company.
