The effect of residual stress or heat on ferroelectrics used to convert photons into electricity was investigated. The data analysis reveals that when the PET-PZT piezoelectric transducer is UV-irradiated with a 405 nm wavelength, it becomes a photon-heat-stress electric energy converter and capacitator. Our objective was to evaluate the PET-PZT photon-heat-stress electric energy conversion performance and the role of the light's wavelength and intensity. Converting waste energy from energy-intensive processes and systems is crucial to reducing the environmental impact and achieving net-zero emissions. To achieve these, innovative materials are needed to efficiently convert ambient energy into electricity through various physical mechanisms, such as the photovoltaic effect, thermoelectricity, piezoelectricity, triboelectricity, and radiofrequency wireless power transfer.
研究了残余应力或热量对用于将光子转化为电能的铁电体的影响。数据分析表明，当PET-PZT压电换能器用405纳米波长的紫外线照射时，它会变成光子-热-应力电能转换器和电容器。我们的目标是评估PET-PZT光子-热-应力电能转换性能以及光的波长和强度的作用。从能源密集型过程和系统中转换废能对于减少环境影响和实现净零排放至关重要。为了实现这些目标，需要创新材料通过各种物理机制，如光伏效应、热电、压电、摩擦电和射频无线电力传输，将环境能量有效地转化为电能。
