    摘要: A back contact type solar battery which provides a reduced electric power loss, free positioning of a bus bar, and a simple manufacturing process. The solar battery includes: semiconductor substrate; first conductivity type region formed on back surface side located on the opposite side of acceptance surface side of the semiconductor substrate; second conductivity type region formed on the back surface side of the semiconductor substrate; first conductivity type collecting electrode linearly formed on the first conductivity type region; and second conductivity type collecting electrode linearly formed on the second conductivity type region. The first and second conductivity type regions are alternately arranged. Each of the first and second conductivity type collecting electrodes has discontinuous places. The discontinuous places of each conductivity type are substantially aligned on straight line in arrangement direction in which the first and second conductivity type regions are alternately arranged.

    摘要: A film may be formed on a surface of a substrate by chemical vapor deposition in a reaction container provided with at least a first holding member that is capable of holding the substrate and a second holding member that is capable of holding the substrate independently from the first holding member, by:
    (a) forming a film on the surface of the substrate by chemical vapor deposition while holding the substrate by the first holding member;
    (b) moving at least one holding member among the first holding member and the second holding member in at least one direction of the upward direction and the downward direction to hold the substrate by the second holding member instead of the first holding member; and
    (c) forming a film on the surface of the substrate held by the second holding member by chemical vapor deposition.
