마이크로 구조물 반사판의 광 회수를 통한 고효율 염료감응형 태양전지 모듈개발

Recently, The Solar Cell Energy is presently promising because of Oil Inflation, fuel exhaustion, global warming and space development. Many advanced countries rapidly develop the solar cell energy under a nation enterprise. Particularly, Dye-sensitized solar cell(DSC) that is the 3rd generation solar cell has low-cost of manufacture about 1/3~1/5 times compared with the silicon solar cell. Accordingly, the DSC is constantly researched globally. In this paper, we have studied a reflector recovering the loss light for improvement conversion efficiency of DSC. The reflector angle was determined by optical analysis program. Micro pyramid patterns with the 112.6° were processed using the ultra precision shaping machine in order to maximize the conversion efficiency due to increasing light distance. In addition, a comparative study carried out about the conversion efficiency.
