Abstract: In this paper, a new type of integrated solar PV/T air collector is designed. A one-dimensional unsteady mathematical model is developed, the internal heat transfer process is calculated by finite difference approach. The performance of PV/T solar air collector is predicted under different parameters and conditions. Results indicate that the temperature of solar cell and outlet air decrease with the increase of air mass flow rate under the same incident solar intensity. Then, the thermal efficiency, electrical efficiency and total efficiency of PV/T system increase with the rising of the inlet air mass flow rate. The models provide valuable theoretical basis for the optimal design of highperformance solar PV/T integrated air system.
