How will you contribute?

The LIST researchers have been working for many years on the definition and implementation of pyroelectric materials capable of producing electrical energy when subjected to thermal potential variations. Their expertise has recently been recognized through a publication in the journal NATURE [1]. This article demonstrates, for the first time worldwide, the experimental possibility of energy production in the Joule domain. This discovery is groundbreaking and opens up brand new development prospects for this technology, which was previously limited to low-power electronic applications (e.g., sensors).

The EFT team has been working for several years (through the SOLINOV project) on energy efficiency, particularly on the development and optimization of self-regulating and innovative Photovoltaic Thermal (PVT) solar panels that simultaneously produce electricity and heat. In current scenarios of using these PVT panels, a significant amount of heat generated during the summer is lost.

The collaboration between the two research laboratories will allow to study and develop an innovative concept for integrating a pyroelectric component into a photovoltaic/thermal solar system. This intelligent coupling will make possible to harness previously lost thermal energy and create a brand new renewable energy generation system.

The PhD candidate will spend two years at IMT premises, followed by two years at LIST premises.

Activities:

• Conduct a preliminary bibliographic study (PVT systems, pyroelectric materials)

• Propose integration configurations for a pyroelectric component in a PVT system

• Perform an energy static study to select preferred integration concepts and carry out initial sizing of the installation

• Conduct thermal and electrical characterization of the selected pyroelectric material for the study

• Contribute to the development of the test bench and laboratory prototype, and carry out an experimental study on the integration of the pyroelectric component

• Model/simulate thermo-fluid exchanges using finite element or volume simulation software, and optimize integration architectures and geometric configurations of the pyroelectric component

• Modify the existing test bench to test the new configurations obtained through simulation, and compare the numerical and experimental results

• Promote the work done by presenting at international conferences and publishing scientific papers in renowned international journals

• During the respective stays at IMT Nord Europe and LIST, teaching involvement will be possible, including conducting tutorials and practical exercises
