The photoelectric film of the blue-band and the purple-band of the bionic micro-nano navigation system is theoretically modeled and characteristically analyzed. The theoretical model of the photoelectric film is focused on the analysis of the effects of the structure and technical parameters of the device itself on the photoelectric conversion efficiency of the device. The relations between different structure parameters, technical parameters and the performance of the film are given, and VC ＋ ＋ is used for programming. The analysis and calculation are simple. By simulating the structure of the optimized film, the optic current density of the model of the film is about 2 mA/cm^2 in the AM1.0 standard. The practicality and reliability of the model are illustrated by the examples,and the model can provide important reference for the design and production of the photoelectric conversion device of the bionic micro-nano navigation system.
