Abstract

Flexible photothermal-electric devices hold great promise for applications such as solar energy conversion and wearable electronics, thanks to their ability to generate green energy, sense temperature, and enhance wearing comfort. However, creating sufficient temperature gradients for optimal power generation along with high-performance multifunctional sensing capabilities remains a significant challenge. In this study, we demonstrate a flexible photothermal-electric device with an exceptional temperature gradient created by a thermal actuator through light-induced thermal deformation. A notable structural feature is the combination of a p-n heterojunction composed of p-type and n-type single-walled carbon nanotubes, which enables the device to achieve a power density of 0.15 μW/cm². Furthermore, the device effectively detects object temperature, ambient light intensity, and environmental humidity. This work opens new avenues for the structural design and manufacturing processes of photothermal-electric devices, paving the way for advanced green power generation and multifunctional sensing applications.

柔性光热电器件及多功能自供电传感器致动器结构设计

由于柔性光热-电器件能够产生绿色能源、感知温度并提高穿着舒适性，因此在太阳能转换和可穿戴电子产品等应用领域具有很大的前景。然而，创造足够的温度梯度以实现最佳发电以及高性能多功能传感能力仍然是一个重大挑战。在这项研究中，我们展示了一种柔性光热电器件，该器件具有由热致动器通过光诱导热变形产生的特殊温度梯度。一个显著的结构特点是结合了p型和n型单壁碳纳米管组成的p-n异质结，使器件的功率密度达到0.15 μW/cm2。此外，该设备还可以有效地检测物体温度、环境光强和环境湿度。这项工作为光热电器件的结构设计和制造工艺开辟了新的途径，为先进的绿色发电和多功能传感应用铺平了道路。
