Large harvested energy with non-linear pyroelectric modules.

ABSTRACT: Coming up with sustainable sources of electricity is one of the grand challenges of this century. The research field of materials for energy harvesting stems from this motivation, including thermoelectrics¹, photovoltaics² and thermophotovoltaics³. Pyroelectric materials, converting temperature periodic variations in electricity, have been considered as sensors⁴ and energy harvesters^5-7, although we lack materials and devices able to harvest in the joule range. Here we develop a macroscopic thermal energy harvester made of 42 g of lead scandium tantalate in the form of multilayer capacitors that produces 11.2 J of electricity per thermodynamic cycle. Each pyroelectric module can generate up to 4.43 J cm^-3 of electric energy
