Research and development of organic UV-Vis-NIR photodetector

Abstract

In recent years, there has been a significant increase in the demand for consumer electronic products. According to a report by ID Tech Ex, it is projected that the market share of these devices will reach a substantial value of $330.3 billion by 2027. To meet the growing demand, organic and hybrid organic/inorganic photodetectors have emerged as promising alternatives to traditional inorganic photodetectors. These photodetectors offer the potential for cost-effective and low-temperature solutionbased processing on flexible substrates, enabling large-scale production through roll-to-roll fabrication. However, the performance of these organic/hybrid photodetectors has been somewhat unsatisfactory, limiting their applications. To enhance their performance, it is crucial to have a comprehensive understanding of how to optimize both material composition and processing parameters. The main objective of this dissertation is to improve the performance of hybrid photodetectors by enhancing material properties and designing innovative device architectures. Specifically, the focus is on developing hybrid photodetectors based on ZnO/P3HT-small molecule blend materials for healthcare applications in the near-infrared (NIR) range.
