Groove machining tool for use with a thin-film solar cell

摘要

There is provided a groove machining tool supported in a holder and caused to move together with the holder in relative fashion along a scheduled scribe line over an integrated thin-film solar cell substrate to form a groove. The groove machining tool includes a tool body supported in the holder, and a blade tip part formed in a distal part of the tool body. The blade tip part includes a blade extending along a direction intersecting a direction of movement of the tool, at a first end along the direction of movement of the tool. The blade is tilted backward from the direction of movement of the tool in relation to a direction orthogonal to the direction of movement of the groove tool, as viewed from a bottom face of the blade tip part.
