我们证明，广泛用于便携式发电设备的太阳能电池可以同时在光学无线通信链路中提取高速数据信号。据我们所知，这封信报道了首次使用有机太阳能电池作为可见光通信（VLC）的能量收集接收器。当在小区中产生最大功率时，通信链路可以使用正交频分复用的实现来提供 34.2 Mbps 的数据速率和 4.08×10−4 的误码率。这种方法可能会在未来的环保 VLC 系统中实现印刷光学数据接收器。数据通信和能量收集的同步功能对未来智能设备的连接具有重大影响，其中许多设备可能成为自供电单元，作为“物联网”的一部分。
We show that solar cells, widely used in portable devices for power generation, can simultaneously extract a high-speed data signal in an optical wireless communication link. This Letter reports, to the best of our knowledge, the first use of an organic solar cell as an energy-harvesting receiver for visible light communications (VLCs). While generating maximum power in the cell, the communication link can deliver a data rate of 34.2 Mbps with a bit error rate of 4.08×10−4 using an implementation of orthogonal frequency-division multiplexing. This approach could lead to printed optical data receivers in future eco-friendly VLC systems. Simultaneous functions of data communication and energy harvesting have great implications for the connectivity of future smart devices, many of which could become self-powered units as part of the “Internet of Things.”
