Simply a function of photoelectric device on the generalized Angle is the photoelectric transformation for the fundamental mode of the device, mainly used for traffic information and energy conversion, the period of photoelectric function as the base of using photoelectric systems, and radio and television function of photoelectric device is the optics and electronics, and so on a series of method combined with the link between the main and related disciplines, Therefore, the photoelectric functional devices have a very important role and significance in optics, optoelectronics and related disciplines. In this paper, the future scientific development and related applications of new photoelectric functional devices are analyzed and the corresponding suggestions and measures are put forward.
