我们表明，有机光催化剂（OPV）是适合的高速光无线数据接收器，也可以收获的权力。此外，这些OPV对于室内应用特别感兴趣，因为它们的带隙大于硅的带隙，从而更好地匹配人造光的光谱。通过选择合适的窄带隙供体聚合物和非富勒烯受体的组合，制备了稳定的OPV，在1个太阳下的功率转换效率为8.8%，在室内照明条件下为14%。在光无线通信实验中，在4 × 4多输入多输出（MIMO）设置中实现了363 Mb/s的数据速率和10.9 mW的同时收获功率，该设置由四个激光二极管组成，每个激光二极管发射56 mW的光功率，并在40 cm距离处的单个面板上作为接收器的四个OPV电池。该结果是使用OPV作为数据接收器和能量收集器的最高报告数据速率。这一发现可能与未来的移动的通信应用相关，因为它能够增强无线数据通信性能，同时延长移动终端中的电池寿命。
We show that organic photovoltaics (OPVs) are suitable for high-speed optical wireless data receivers that can also harvest power. In addition, these OPVs are of particular interest for indoor applications, as their bandgap is larger than that of silicon, leading to better matching to the spectrum of artificial light. By selecting a suitable combination of a narrow bandgap donor polymer and a nonfullerene acceptor, stable OPVs are fabricated with a power conversion efficiency of 8.8% under 1 Sun and 14% under indoor lighting conditions. In an optical wireless communication experiment, a data rate of 363 Mb/s and a simultaneous harvested power of 10.9 mW are achieved in a 4-by-4 multiple-input multiple-output (MIMO) setup that consists of four laser diodes, each transmitting 56 mW optical power and four OPV cells on a single panel as receivers at a distance of 40 cm. This result is the highest reported data rate using OPVs as data receivers and energy harvesters. This finding may be relevant to future mobile communication applications because it enables enhanced wireless data communication performance while prolonging the battery life in a mobile device.
