Abstract: The space environment effect detector with red-blue optical sensitivity solar cells, including GaInP2 and GaInP2/GaAs/Ge solar cells, can be used for detecting contamination, atomic oxygen and radiation environment and the related effects. With the detector, a large number of effective detecting data are obtained through XY-1 developed by China Academy of Space Technology. The detected data from the space environment effect detector in one year are analyzed and it is concluded that the power of the contamination detector is declined by 2.7%, the equivalent contamination deposited mass is 2.23×10^-5 g/cm² and the average value is 6×10^-8 g/cm² per day. The atom oxygen flux is 9.7×10²⁰ AO/cm² in eleven months at the altitude of 499.226 km. The cumulate irradiation dose (equivalent 1 MeV electron fluence) of the radiation effect detector (with three junction GaAs solar cells) for 1 year in orbit is 5.49×10¹¹ e/cm².
