Optoelectronic devices that are self-powered and have a high transparency are of interest for application in versatile next-generation “see-through” platforms. However, current optoelectronic photodetectors often have drawbacks including a high driving power and a relatively slow response speed. In this work, large-area transparent photovoltaic devices (TPVD) are reported that can be easily prepared at room temperature from eco-friendly and abundant materials. The TPVD consists of a zinc oxide/nickel oxide heterostructure as the light-harvester and ultraviolet (UV) blocker, and its photovoltaic performance is evaluated using silver nanowire (AgNW) electrodes composed of NWs with varying diameters. As a result of surface plasmons in the AgNW electrode, TPVDs with AgNWs that have a larger diameter exhibit enhanced transparency and photovoltaic performance, with a photovoltage of 520 mV under standard AM1.5 light illumination. Importantly, the binary electric signal produced can be decoded without the need for electronic filter circuits or a threshold. A UV communication system is further designed based on the TPVD for application as a self-powered, binary Morse-code signal with a high response speed. This work integrates the features of a transparent power generator and transparent optoelectronics into a UV photodetector, and it can enable the application of self-reliant devices for communications, imaging, and sensors.

用于高速二元紫外通信窗口的全金属氧化物透明光伏

自供电且具有高透明度的光电设备对于在多功能的下一代“透视”平台中的应用很感兴趣。然而，目前的光电探测器往往具有驱动功率大和响应速度相对较慢的缺点。在这项工作中，据报道，大面积透明光伏器件 (TPVD) 可以在室温下由环保且丰富的材料轻松制备。TPVD 由氧化锌/氧化镍异质结构组成，作为光收集器和紫外线 (UV) 阻挡器，使用由不同直径的纳米线组成的银纳米线 (AgNW) 电极评估其光伏性能。由于 AgNW 电极中的表面等离子体激元，具有更大直径的 AgNW 的 TPVD 表现出增强的透明度和光伏性能，在标准 AM1.5 光照下光电压为 520 mV。重要的是，产生的二进制电信号可以在不需要电子滤波器电路或阈值的情况下被解码。进一步设计了基于 TPVD 的 UV 通信系统，作为具有高响应速度的自供电二进制莫尔斯电码信号应用。这项工作将透明发电机和透明光电子学的特性集成到紫外光电探测器中，它可以实现自力设备在通信、成像和传感器方面的应用。产生的二进制电信号可以在不需要电子滤波器电路或阈值的情况下被解码。进一步设计了基于 TPVD 的 UV 通信系统，作为具有高响应速度的自供电二进制莫尔斯电码信号应用。这项工作将透明发电机和透明光电子学的特性集成到紫外光电探测器中，它可以实现自力设备在通信、成像和传感器方面的应用。产生的二进制电信号可以在不需要电子滤波器电路或阈值的情况下被解码。进一步设计了基于 TPVD 的 UV 通信系统，作为具有高响应速度的自供电二进制莫尔斯电码信号应用。这项工作将透明发电机和透明光电子学的特性集成到紫外光电探测器中，它可以实现自力设备在通信、成像和传感器方面的应用。
