摘要

在过去的几年里，废热收集领域经历了显著的增长。利用热释电材料PbZrxTi1-xO3 (PZT-5H)进行了热辐射转换电能的实验研究。将热释电材料暴露在0.5 Hz恒定频率的紫外灯下，通过自然风机连续冷却样品的另一个表面(使材料产生连续的时间梯度)。在无负载电阻的情况下，储能最大值为1.75µJ，跨越100µF。在负载电阻为3 MΩ和10µF时，最大输出功率为0.76µW。

Harvesting thermal energy (via radiation) using pyroelectric materials (PZT-5H): An experimental study

ABSTRACT The field of waste thermal energy harvesting has experienced significant growth over the past few years. This paper presents an experimental study on thermal radiation to electrical energy conversion using pyroelectric material (PbZrxTi1-xO3 (PZT-5H)). Pyroelectric material was exposed to UV lamp with a constant frequency of 0.5 Hz and another surface of sample was continuously cooled via natural air fan (for generation continuous temporal gradient in material). Maximum value of stored energy was 1.75 µJ across 100 µF without load resistance. Maximum power output was found to be 0.76 µW across load resistance of 3 MΩ and 10 µF.

期刊介绍： Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
