Decrease in the efficiency of solar batteries on spacecraft under the influence of space radiation is studied. A simple mathematical model describing the process of photoconverter degradation is suggested. The fit between calculations with the formula Í = φ + (1 -φ)ехр(-τ/θ)  and experimental data is analyzed. The numerical values of the parameters φ  and θ and found from the analysis allow the estimation of temporal changes in the output characteristics of solar batteries aboard satellites and other spacecraft at the design stage
