The power generation system using the solar energy of this research is a system which separates the energy of the domain which matched the sunlight sensitivity characteristic of a solar cell, and the energy of the infrared domain which does not contribute to power generation, and generates each by photo-voltic conversion and thermoelectric conversion. Since the electromotive power of thermoelectric conversion is proportional to the 2nd power of the difference of temperature of a high temperature end and a low-temperature end, high efficiency is attained by raising heat-flux. Therefore, condensing (heat) contributes to the improvement in power generation efficiency. When a condensing ratio generates electricity combining the condensed type solar cell of 200-300, and thermoelectric power generation, a system with a high performance can be attained as compared with the former.
