Abstract

This paper about the small electron beam irradiator for solar cell´s efficiency. Many things are studied by method to increase conversion efficiency of solar cell. We selected electron beam by method for conversion efficiency of solar cell. Energy bands of this electron beam irradiator is 80 keV (max.). And, solar cells that apply in this paper are crystal S. Average efficiency of solar cell that applies in this experiment is 10%. This system manufactured small size electron beam irradiator. And, electron beam irradiation to solar cell in vacuum chamber of this irradiator. Irradiation area is 20*20 [mm²] by 30∼70 [keV].
