How will you contribute?

Electric energy stands for 20% of the total energy consumed in the world, and this share is expected to reach 40% by 2050 as an outcome of the need to decrease our dependence on non-renewable energies. Beyond sunlight and wind, heat is another formidable and poorly exploited source of electrical energy. Indeed, currently 72 % of the energy produced ends up in waste heat - and it has been predicted that up to 13 000 TWh could be recovered each year, which stands for Europe’s yearly total energy needs! In this context, our team recently showed that 40 grams of nonlinear pyroelectric ceramics can generate more than 10 Joules of electric energy from waste heat in one single thermodynamic cycle of 100 degrees (Lheritier et al., Nature 2022).

In this post doc, we want to study efficiency. Indeed, pyroelectric energy harvesting should have an intrinsic advantage when it comes to efficiency. However, this is not easy to put in place experimentally. This is what we want to investigate here. More specifically, we want to study pyroelectric modules assembled in a device exchanging heat with a fluid. The fluid movement, its temperature, the current and voltage applied to the pyroelectric modules will be controlled and monitored to give the opportunity to assess the overall efficiency. Modelling the overall behaviour of the device will be required, through finite element modelling (Comsol). The majority of the work will nonetheless be experimental, by fabricating the devices and testing them in the lab. The post doc will be part of a larger team working on electrocaloric cooling and pyroelectric energy harvesting.
