Abstract

Among various types of photo-electric energy conversion element which can transfer solar energy into electric energy through the photo voltaic effect, Si solar cells were investigated on photoelectric characteristics, improvements of its efficiency and economical evaluation for its production cost. To study the above subjects, we decided best conditions on fabricating of thin film Si solar cell by epitaxial growth and knew that the thin solar cell by epitaxial growth was more efficient than that by diffusion process. And also higher photo voltaic output was obtained as a effect of SiO as antireflection coating by several methods, i.e. vacuum evaporating techniques of electrode to decrease the contact resistance and to form best ohmic contact, and concentration techniques of sun's ray by lenz or both-sided illumination through special structure for reflection using mirrors.
