Abstract

Organic photodiodes (OPDs) have shown great promise for potential applications in optical imaging, sensing, and communication due to their wide-range tunable photoelectrical properties, low-temperature facile processes, and excellent mechanical flexibility. Extensive research work has been carried out on exploring materials, device structures, physical mechanisms, and processing approaches to improve the performance of OPDs to the level of their inorganic counterparts. In addition, various system prototypes have been built based on the exhibited and attractive features of OPDs. It is vital to link the device optimal design and engineering to the system requirements and examine the existing deficiencies of OPDs towards practical applications, so this review starts from discussions on the required key performance metrics for different envisioned applications. Then the fundamentals of the OPD device structures and operation mechanisms are briefly introduced, and the latest development of OPDs for improving the key performance merits is reviewed. Finally, the trials of OPDs for various applications including wearable medical diagnostics, optical imagers, spectrometers, and light communications are reviewed, and both the promises and challenges are revealed.

有机光电二极管:器件工程与应用。

有机光电二极管(OPDs)由于其宽范围可调的光电特性、低温易加工和优异的机械灵活性，在光学成像、传感和通信领域显示出巨大的应用前景。在探索材料、器件结构、物理机制和加工方法方面进行了大量的研究工作，以提高opd的性能，使其达到无机同类产品的水平。此外，根据opd的展示和吸引人的特点，建立了各种系统原型。将器件优化设计和工程与系统需求联系起来，并检查opd在实际应用中的现有缺陷，这一点至关重要，因此本文将从讨论不同预期应用所需的关键性能指标开始。然后简要介绍了OPD器件结构和工作机理的基本原理，综述了OPD器件在提高关键性能方面的最新进展。最后，回顾了opd在可穿戴医疗诊断、光学成像仪、光谱仪和光通信等各种应用领域的试验，并揭示了opd的前景和挑战。
