Outline of Final Research Achievements

I researched how to carry out solar cell manufacturing training even if I do not have a semiconductor manufacturing device.
As a result, we devised a method to carry out from the production of solar cells to the drive of solar motors in two frames. Furthermore, when the deterioration of the solar cell characteristics when the thermal diffusion time was shortened was investigated, it became clear from the reverse direction characteristics in the rectification characteristics that the leakage current, which causes the deterioration of the solar cell characteristics, increases when the diffusion time is shortened. rice field. It was thought that if the diffusion time was shortened, the leakage current would increase because the alloy would increase the number of incomplete joints.

Academic Significance and Societal Importance of the Research Achievements

近年,地球温暖化への懸念などによってエネルギー問題への関心が高まり再生可能エネルギーの1つとして太陽電池は注目されている.研究代表者は,半導体製造装置をほとんど備えていなくても,通常の実験室のような環境において太陽電池の製作実習を実施する方法について研究した.太陽電池の製作からソーラーモータ駆動までを2コマで実施する方法を考案し,その結果,学期中の学生実験等への導入が時間的に可能となることがわかった.このことから,多くの学生等に太陽電池製作からモータ駆動までを体験させることができ,太陽光発電の原理や半導体物性を深く学ぶきっかけとなると期待される.
