通过调控SmFeO3在PVDF中的浓度及紫外光照射增强摩擦纳米发电机的电压输出

The present work deals with the improved output voltage characteristics of Triboelectric Nanogenerator (TENG) devices with the incorporation of SmFeO 3 -PVDF as a layer and exposure with UV radiation. A constant concentration of TiO 2 (4 wt%) and two devices with varying SmFeO 3 (1 wt% and 2 wt%) concentrations were examined. The findings demonstrate that larger SmFeO 3 concentrations result in higher voltage outputs. Device 1 containing 1 wt% SmFeO 3 achieved a voltage output of 99.6 V without UV and 111.3 V with UV exposure, while device 2 with 2 wt% SmFeO 3 content produced a voltage output of 105.5 V without UV and 123.0 V with UV exposure. This implies that a greater SmFeO 3 concentration causes more charges to be generated and separated, which raises the output voltage. Consequently, by taking advantage of this phenomenon, greater voltage outputs may be produced and a better TENG device may be designed.
