전극형성과 태양전지 모듈 일체화 기술 개발에 적용되는 태양전지 전극 설계 기술

다국어 초록 (Multilingual Abstract)

This study was on electrode design for the realization of a solar cell that combines electrode formation and module integration process to overcome printing limitations. We used the passivated emitter rear contact (PERC) solar cell. Wafer size was 156.75 mm ×156.75 mm. The fabricated cell results showed that the open-circuit voltage of 649 mV, short-circuit current density of 36.15 mA/㎠, fill factor of 68.5%, and efficiency of 16.06% with electrode conditions the 24BBs with the width 190 μm and 90FBs with the width 45 μm. For improving efficiency, the characteristics of the solar cell were checked according to the change in the number of BBs and FBs and the change in line fine width. It is confirmed that the efficiency of the solar cell will be improved by increasing the number of FBs from 90 to 120, and increasing the line width of the FBs by about 10 μm compared to the manufacturing solar cells.
