碩士 === 國立雲林科技大學 === 電子與資訊工程研究所碩士班 === 92 === This paper is making a study of single-crystalline silicon solar cell process and technique. The inverted pyramids are fairly good structure for sealing light. The inverted pyramids are etched by KOH solution and to discuss influence of etching rate for anisotropic etching. Furthermore, coating antireflection layer can increase in absorbing light. Boron or phosphorous plate is using to solid state thermal diffusion and doping impurities in solar cell in this research. Illuminance of short wavelength is much more on earth’s surface. In order to absorb carrier that exciting by short wavelength and avoid carrier recombination before arriving junction, the shallow junction is required. Doping boron impurities to form back surface field (BSF). BSF can absorb majority carrier and spring minority carrier. The electrode is made by lift off process that using thick photoresister. The electrode is like “finger” to avoid cover surface. Heavily doping to make ohmic contact where situated between electrode and silicon. Taking Xenon light source to measure solar cell in order to discuss the performance of shallow junction and BSF. In order to match up solar spectrum, measure frequency response by monochromatic light for solar cell. To develop coordination of solar spectrum response can promote efficiency for solar cell.
