碩士 === 國立成功大學 === 化學系碩博士班 === 101 === This study discussed with fabrication of zinc selenide by using eletrodeposition at various electrolytes and temperature. The diffusion coefficient of electrolytes was calculated by Fick’s law and it woule affect the current density, thickness and particle size. The films of zinc selenide had quantum confinement effect and red shift of transmittance due to the particle size, and it caused the band gap that we calculated by Tauc-Sunds equation had red shift as well. On the other side, the reduction potential shifted more positive when the temperature raised, it also make different electrochemical reations occurred, the different reaction led the films to different proportion of element. We observed the fabrication of zinc selenide in eighty Celsius degree its crystallinity had more intense than forty-five and sixty-five Celsius degree, the value of band gap and lattice constant were more closer to theoretical value in eighty Celsius degree as well. This trend may reduce the carrier recombination to fabricate the solar cells p-n junction.
