表面張力とガス流を利用した極薄金属板の試作実験

抄録

The purpose of this study is to develop a new process for making silicon plate of less than 100 μm. Silicon plate of less than 100μm will become flexible and be utilized for flexible solar panels. Although experiments with high-temperature molten silicon were difficult to do in our laboratory, we performed model experiments with low melting point metal. In the experiment, we attempted to solidify a metal plate less than 100 μm utilizing surface tension of the molten metal. Moreover, we attempted to apply gas flow, as external force, to the molten part before solidification to make the plate thinner. As a result, metal plate became thinner than previous experiment. However, the plate width became narrower. We need to investigate the cause of becoming narrow of the metal plate width.
