光照射型熱電子コンバータの電位分布に関する研究

Abstract

The thermonic converter is one of direct generation, and it has many advantages. But the high operating temperature makes shortening of emitter's life. When the thermonic converter is irradiated by a light, the higher output current is obtained at the relatively lower emitter temperature. But it has not been understood why the output of the thermonic converter increased by the light irradiation. So the distribution of electric potential between the electrodes was theoretically analyzed. The potential distribution was calculated by integrating Poisson's equation. As a result of the calculation, it was seen that the photo-ionized electric charge made the potential barrier a sharp degrease. It was able to analyze quantitatively the output increase of the light irradiated thermonic converter.
