Third-generation photovoltaic semiconductors have the unique advantages of solution-compatible low-cost processing, transparency, flexibility, large-area film formation, photo-responsive and ion-transport capabilities. Focusing on devices prepared from such semiconductor materials, this paper reviews recent advances in organic photovoltaic as well as organic/inorganic hybrid perovskite photovoltaic, and explores their significant advantages in application scenarios such as flexible self-powered electricity supply and building integrated photovoltaic. At the same time, the development of thirdgeneration light-emitting diode in terms of material selection and structural design, and their application prospects in the field of lighting and display are discussed. In addition, the latest advances of third-generation semiconductor materials in artificial optoelectronic synapses are discussed, mainly focusing on new mechanisms, new device structures, and new functions. The latest applications of artificial synaptic devices in integrated sensing-memory-computing chips, neural networks, and intelligent bionic devices are also introduced. The key scientific issues for the field are briefly summarized, and an outlook for future scientific research and application breakthroughs is presented.
