20110126902APPARATUS AND METHOD FOR MANUFACTURING THIN FILM SOLAR CELL, AND THIN FILM SOLAR CELL - An apparatus for manufacturing a thin film solar cell that increase homogeneity in film characteristics. In a process of conveying a substrate from one roll to another roll, a power generation layer, which is a laminated body of a plurality of semiconductor layers, is formed in a plurality of film formation compartments partitioned along a conveying direction between the roll pair. A plurality of flat application electrodes are laid out in the conveying direction facing toward the substrate in each film formation compartment. Each flat application electrode includes a power supply terminal supplied with high frequency power in a VHF band. When the wavelength of the high frequency power is represented by λ, the distance between an edge of the flat application electrode and the power supply terminal is set to be shorter than λ/4 in a direction orthogonal to the conveying direction.06-02-2011
