a-Si 박막태양전지의 Shading 면적과 위치에 따른 출력 특성 변화

It is known that shading acts on Power Drop of a-Si:H thin film photovoltaic module. However, the uniformity of thin film PV module is important better than anything. Because non-uniform functions as a shading. In this paper, it is verified that deposited layer's uniformity affects on resistance locally through shading experiment method. Sectional non-uniform resistance changes resistivity of solar cell and electric field. Actually a-Si:H thin film PV module manufacturing process' characteristic affects on uniformity. But we don't have to ignore uniformity, because solar cell is influenced by resistance. From this point of view the deposition rate uniformity will be discussed.
