In higher education institutions such as universities and colleges of technology, practical and theoretical education of semiconductor devices is required. Therefore, we introduce a silicon (Si) solar cell fabrication into student experiment to make them understand the pn junction as a basis of semiconductor devices. Furthermore, spectral response characteristic measurement using light emitting diodes (LED) and energy conversion efficiency simulation of the solar cell are introduced into the student experiment to make them understand the relation between light energy and energy band gap, and the function of minority carriers. We verify the effectiveness of introducing these experiments by conducting examination and questionnaire before and after the experiment.
