Gravure off-set 인쇄법을 적용한 고효율 다결정 실리콘 태양전지 = Gravure off-set printing method for the high-efficiency multicrystalline-silicon solar cell

다국어 초록 (Multilingual Abstract)

The most widely used method to form an electrode in industrial solar cells are screen printing. Screen printing is characterized by a relatively simple and well-known production sequence with high throughput rates. However the method is difficult to implement a fine line width of high-efficiency solar cells can not be made. The open circuit voltage(Voc) and the short circuit current density(Jsc) and fill factor(FF) need to be further improved to increase the efficiency of silicon solar cells. In this study, gravure offset printing method using the multicrystalline-silicon solar cells were fabricated.
Gravure off-set printing method which can print the fine line width of finger electrode can have the ability reduce the shaded area and increase the Jsc. Moreover it can make a high aspect ratio thereby series resistance is reduced and FF is increased. Approximately 50㎛ line width with 35㎛ height was achieved. The efficiency of gravure off set was 0.7% higher compare to that of scree printing method.
