Abstract: The humankind has made remarkable social development with the Industrial Revolution. The invention of the steam engine, which converts thermal energy into power, has expanded the use of energy and caused energy consumption to increase rapidly. Moreover, the field of human activity has grown explosively in the last hundred years of the twentieth century due to scientific and technological advances. However, the large amount of fossil fuels consumption such as coal and oil has brought the influence which is not wealth on human beings. The global environmental problems including a global warming, etc. are occurring in the world. So, in recent years, it is necessary to research the international study for the countermeasures. In this research, we propose the system of dividing solar energy by the wavelength selection into an infrared range and a visible light range by using a heat radiation reflective film. The improvement of total thermal efficiency by the cascading energy use is important to use the solar energy effectively. On this system, we perform thermoelectric power generation system using the energy of an infrared range and generate power by a photovoltaic cell with the energy of a visible light range. Furthermore, we use effectively the hot water obtained by cooling of the thermoelectric conversion module in this system. The purpose of this research is to improve a total thermal efficiency by using solar energy multiply.
