결정질 실리콘 태양전지의 전극 종횡비 개선과 전극 간 간격이 효율에 미치는 영향 분석 = The Analysis on the Effect of Improving Aspect Ratio and Electrode Spacing of the Crystalline Silicon Solar Cell

다국어 초록 (Multilingual Abstract)

The screen printed technique is one of the electrode forming technologies for crystalline silicon solar cell. It has the advantage that can raise the production efficiency due to simple process. The electrode technology is the core process because the electrode feature is given a substantial factor (for solar cell efficiency). In this paper, we tried to change conditions such as squeegee angle $55{\sim}75^{\circ}$, snap off 0.5~1.75 mm, printing pressure 0.6~0.3 MPa and 1.6~2.0 mm finger spacing. As a result, the screen printing process showed an improved performance with an increased height higher finger height. Optimization of fabrication process has achieved 17.48% efficiency at screen mesh of 1.6 mm finger spacing.
