Abstract: The present invention provides an inspection apparatus for photovoltaic devices which electrifies the photovoltaic devices in a forward direction thereof to make the photovoltaic devices emit electro-luminescence light and which has a simple-structured and cheap darkroom. The inspecting apparatus of the present invention includes a darkroom (110) provided with a flat upper surface (111), a transparent plate (112) which is provided in the upper surface of the darkroom for disposing the photovoltaic devices as an inspecting object (200), a reflector (140) which is disposed in the darkroom (110) at an oblique angle to the transparent plate, and a shading member for covering a camera (120) which is provided in the darkroom (110), the photovoltaic devices as the inspecting object on the darkroom and a guide member for transporting the photovoltaic devices.

Abstract: A method and apparatus for soldering interconnectors to photovoltaic cells that, after soldering, prevents bending of the photovoltaic cells due to heat warping caused by heat contraction of the lead wires. The interconnectors are positioned at predetermined positions on the photovoltaic cell, the interconnectors and the photovoltaic cells are held tightly together, and the solder is melted as the photovoltaic cells are heated, after which the photovoltaic cells are sequentially cooled in the long direction of the interconnectors with cold blasts from the end of the photovoltaic cells in the long direction of the interconnector.

Abstract: A photovoltaic cell holder to hold a photovoltaic cell and interconnectors for soldering the interconnectors to top and bottom surfaces of the photovoltaic cell has an upper holder and a lower holder. The upper holder includes an upper retainer to press the interconnectors against the top surface of the cell. The upper retainer includes multiple elastic stick-shaped members and one or more flange parts provided at one end of the stick-shaped members. The lower holder includes one or more bar-shaped lower supports to support the interconnectors against the bottom surface of the cell. The lower supports extend parallel to the interconnectors, and a surface of each lower support that contacts the interconnectors has either a groove or a hole. The photovoltaic cell holder holds the interconnectors tightly over substantially all areas to provide uniform welding quality while allowing flux gas to escape to prevent the cell from bending during soldering.
