Both the producing of electricity and the collecting of thermal energy could be achieved by the using of Photovoltaic/thermal solar system. The basic form of the representative photovoltaic/thermal solar collectors and the new photovoltaic/thermal solar collectors were introduced. The features of the photovoltaic/thermal solar collectors were researched. Both electricity and thermal energy could be obtained through photovoltaic/thermal integrated building applications. The energy could be utilized. A great foreground was obtained.
