This work reports the first photovoltaic-powered transparent heater and the results suggest their potential for future smart window applications. Transparent heaters are of high interest for application in windows of buildings, automobiles, and aircrafts to ensure clear vision. Here, we propose the photovoltaic-transparent heater system to supply electric power for Joule heating of the transparent heater. The transparent heater is composed of silver nanowire (AgNW) networks to induce heat via the Joule effect. To ensure high stability, a ZnO film is applied as a transparent protection film to the AgNW networks, and it also serves as a thermal conductor for the transparent heater system. The proposed ZnO-coated AgNW transparent heater efficiently uses the Joule effect via the metal nanowire network, resulting in a high operating temperature >300 °C. The ZnO coating is also very effective in maintaining the optical transparency of the heater >67% in the visible spectral range. For on-site application, the ZnO/AgNW transparent heater is powered by photovoltaic cells and drives the heating temperature of 58 °C. The self-powered transparent heaters are therefore considered as suitable for application in transportation, buildings, wearables, and remote heating systems as a smart-window energy system.

这项工作报告了第一台以光伏为动力的透明加热器，结果表明了它们在未来智能窗户应用中的潜力。透明加热器对于在建筑物，汽车和飞机的窗户上使用以确保清晰的视野非常感兴趣。在这里，我们提出了光伏透明加热器系统，以为透明加热器的焦耳加热提供电力。透明加热器由银纳米线（AgNW）网络组成，以通过焦耳效应感应热量。为了确保高稳定性，ZnO膜用作AgNW网络的透明保护膜，并且还用作透明加热器系统的热导体。拟议的ZnO涂层AgNW透明加热器通过金属纳米线网络有效利用焦耳效应，从而导致较高的工作温度> 300℃。ZnO涂层在保持可见光谱范围内的加热器的光学透明度> 67％方面也非常有效。对于现场应用，ZnO / AgNW透明加热器由光伏电池供电，加热温度为58°C。因此，自供电透明加热器被认为适合作为智能窗能源系统应用于交通，建筑物，可穿戴设备和远程加热系统。
