本文提出了一种用于物联网（IoT）应用的新解决方案，其中GaAs太阳能电池用于传输信息。通过调制太阳能电池的光致发光和电致发光发射，利用太阳能电池的信息传输是可能的。光致发光通过开关进行调制，以使太阳能电池端子短路。电致发光调制通过向电池施加时变电压来实现。太阳能电池还可以用于接收编码为光强度变化的信息。此外，太阳能电池还可以用于其收集环境辐射能的预期功能。因此，配备有GaAs太阳能电池的设备可以将其板上太阳能电池重复用于多种目的，从而使设备具有更低的成本、尺寸和复杂性。被称为光学频率识别（OFID）设备的拟议设备适用于物联网应用，其中无线通信和能量收集是必需的功能。大量的实验证明了所提出的解决方案的有效性。
This paper presents a new solution for Internet-of-Things (IoT) applications in which GaAs solar cells are employed to transmit information. Transmission of information with a solar cell is possible by modulating the photo-luminescence and the electro-luminescence emissions of the solar cell. Photo-luminescence is modulated with switch to short circuit the solar cell terminals. Electro-luminescence modulation is achieved by applying a time-varying voltage to the cell. The solar cell can also be used to receive information encoded as light intensity variations. Moreover, the solar cell can also be used for its intended function of harvesting ambient radiant energy. Hence, a device equipped with a GaAs solar cell can reuse its on-board solar cell for multiple purposes resulting in devices with lower cost, size and complexity. The proposed devices, which are called Optical Frequency Identification (OFID) devices, are suitable for IoT applications in which wireless communications and energy harvesting are required features. A number of experiments are presented to demonstrate the validity of the proposed solution.
