Abstract

In this article, we compare two different kinds of commercial light-emitting diodes (LEDs) in transmission and organic photodetectors based on poly(3-hexylthiophene) (P3HT) and a phenyl-C61-butyric acid methyl ester (PCBM) blend used as active layer in reception. Photovoltaic cells based on massive heterojunctions of semiconductor polymers have focused the attention of researchers due to their several potential advantages over their inorganic counterparts, such as their simplicity, low cost, and ability to process large area devices, even on flexible substrates. Furthermore, in logistics, storage management systems require the implementation of technological solutions that allow the control of merchandise in real time by means of light-emitting diode signals that send information about the product. However, the slow response time of these organic photodetectors should not be critical for this application, where the light intensity changes are very slow, which limits the speed of data transmission compared to inorganic based systems that use wireless optical communications. Finally, we show a low-cost visible light communication system based on organic photodetectors with a frame based on on-off keying with Manchester encoding to support device-to-device connections.

摘要

在本文中，我们比较了两种不同的商用发光二极管（LED）在发射方面的情况，以及基于聚（3 - 己基噻吩）（P3HT）和苯基 - C61 - 丁酸甲酯（PCBM）混合物作为接收层的有机光电探测器的情况。基于半导体聚合物大规模异质结的光伏电池因其相对于无机同类产品具有的几个潜在优势而受到研究人员的关注，例如其简单性、低成本以及能够加工大面积器件，甚至在柔性基板上。此外，在物流中，存储管理系统需要实施技术解决方案，以便通过发送有关产品信息的发光二极管信号实时控制商品。然而，这些有机光电探测器的缓慢响应时间对于此应用而言不应是关键问题，因为在此应用中光强度变化非常缓慢，这与使用无线光通信的无机系统相比限制了数据传输速度。最后，我们展示了一种基于有机光电探测器的低成本可见光通信系统，其帧基于带有曼彻斯特编码的开关键控，以支持设备到设备的连接。
