A solar chimney PV/T power plant (SCPVTPP) is proposed. Mathematical models are established for the PV/T solar collector,\nthe chimney, and the power conversion unit, respectively. Performances of the designed SCPVTPP are then simulated. The\nSCPVTPPs with different PV module areas are finally discussed. It is found that the PV cells hold the highest temperature in\nthe solar collector. Temperature rise of the PV module has significant influences to its power generation. Without cooling, the\nPV power capacity has an average decrease of 28.71%. The contradictory influences of temperature rise and airflow cooling\nlead to an 11.81% decrease of the average power capacity. By adding the power generated by PVT, the total PV-related power\ncontribution increases by 4.72%. With the increase of the solar collector ratio, the temperature rise and the wind velocity both\nfirst decrease then increase, the SCPP power productivity decreases linearly, and the PV power productivity increases linearly,\nwhereas the PVT power productivity first increases linearly then increases superlinearly. There is a reversed solar collector\nratio, exceeding which the PV generates most power. In this study, solar thermal power takes the major role when the solar\nPV area ratio is smaller than 0.055.
