Advanced Organic-Inorganic Hybrid Materials for Optoelectronic Applications

Research on organic-inorganic hybrid materials (OIHMs) has experienced explosive growth in the past decades. The diversity of organic components allows for the introduction of various spatial scales, functional groups, and polarities, while inorganic components provide higher hardness, heat resistance, and stability, their flexible combination facilitates the formation of diverse structures. Furthermore, simple and cost-effective synthesis methods, such as room temperature solution processes and mechanochemical techniques, enable precise control over the materials' properties at different scales, thus achieving adjustable structure-performance relationships. This review will discuss the recent research progress of OIHMs within the field of optoelectronics and related optoelectronic device applications. According to the dimension of inorganic components and the nature of organic-inorganic interface, this review divides OIHMs into four structural categories. The ongoing research has revealed diverse applications for OIHMs in the fields of solar cells, light-emitting devices, detectors, and memristors. As an outlook, the potential of perovskite and 0D metal halide materials, which are currently the most studied, for enhancing optoelectronic performance and stability is discussed. Organic-inorganic hybrid materials have become predominant in optoelectronics over the past decades. The rational combination of organic and inorganic components increases the diversity of composition forms and shows unique advantages in synthesis methods, mechanical properties, and optoelectronic properties. These materials reach or exceed the standards of traditional materials in applications such as solar cells, light-emitting diodes, and photodetectors. image
