Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, in particular to a wide spectrum response photoelectric detector. Background technique [0002] Optical detector is a new type of detection technology, which is widely used in environmental monitoring, astronomy, national defense and military, and sky communication. The photodetectors currently used are mainly photodiodes, which are large in size, high in operating voltage, and expensive in equipment. Organic photodetectors will find applications in consumer electronics, household appliances, smart building lighting, industry, production safety, health care and life sciences, environment, toys, and education due to their many advantages such as flexibility, cheapness, and ease of integration. Wide range of applications. [0003] Due to the limited absorption band of organic photoelectric materials, traditional organic photodetectors have a narrow response wavelength coverage, an...
