Photodetector as a key component of photovoltaic systems , with the development of photovoltaic technologies increasingly showing its importance. At present, there photodetector Testing System test object and shortcomings of a single test project , for which this paper has developed a photoelectric detector features integrated experimental system . The system uses a common optical system and the mechanical structure , the shared amplification method to achieve a variety of circuit characteristics of the test photodetector integration of the existing system can not compensate for a variety of characteristics of the photodetector while the lack of testing , the realization of the same the platform quickly to the characteristics of the photodetector various parameters are tested . The detector system is currently available tests are: a photodiode , phototransistor , photoresistor , silicon photocell , avalanche photodiodes and photomultiplier tubes . The system is structured around the optical system and mechanical grating monochromator for building ; data processing and control section to AT89C51 microcontroller as the core processor for data acquisition and on-site control , and through the RS-232 serial communication port for data communication with the computer computer software for data corresponding to the last processed in an appropriate way data is represented test results are given . This paper describes the various photodetectors in detail the basic principles and characteristics of parametric test based on the principle , further elaborated the overall design of the system , the system's hardware and software design , the experimental system is given several sets of test results .
