Abstract

In this study, we investigate the conversion of light-induced thermal energy to electrical energy by exploiting the piezo- and pyroelectric effect of polyvinylidene fluoride (PVDF). Due to the transparency, high conductivity, surface coverage and a facile and scalable deposition process, spray-coated silver nanowire (AgNW) and PEDOT:PSS hybrid films are used as transparent top and bottom electrodes. By adding ethylene glycol, a high boiling point solvent, the conductivity of the PEDOT:PSS films is increased by 5 orders of magnitude, up to 1816 S/cm. For an illuminated area of 8 cm⁁2 and a temperature variation of 5.7 °C, the power output of the PVDF foil reaches 413 nW at a voltage of 4.3 V and a current of 96 nA. These values compare well to the state-of-the-art performance of pyroelectric harvesters based on PVDF. As a possible application, we propose the use of this material system for a self-powered light and temperature sensor node.

利用具有高导电性和透明银纳米线/PEDOT:PSS混合电极的PVDF从环境光中收集能量

在这项研究中，我们研究了利用聚偏氟乙烯(PVDF)的压电和热释电效应将光诱导的热能转化为电能。由于透明、高导电性、表面覆盖以及易于扩展的沉积工艺，喷涂银纳米线(AgNW)和PEDOT:PSS混合薄膜被用作透明的顶部和底部电极。通过加入乙二醇(一种高沸点溶剂)，PEDOT:PSS薄膜的电导率提高了5个数量级，达到1816 S/cm。当光照面积为8 cm × 2，温度变化为5.7℃时，PVDF箔在4.3 V电压和96 nA电流下的输出功率可达413 nW。这些值与基于PVDF的热释电收割机的最先进性能相比较。作为一种可能的应用，我们建议将这种材料系统用于自供电的光和温度传感器节点。
