  • Publication number: 20110287568
    Abstract: A method of manufacturing a thin film solar cell includes a bonding step of bonding a bus bar on a back face electrode layer of a solar cell string including a transparent conductive film, a photoelectric conversion layer and the back face electrode layer formed on a light-transmitting insulating substrate. The bonding step includes a first step of bonding conductive tape on the bonding surface of the bus bar that is to be bonded to the back face electrode layer, and a second step of bonding the bus bar to which the conductive tape has been bonded to the back face electrode layer of the solar cell string.

  • Patent number: 7990495
    Abstract: A method for cutting apart a glass substrate is provided whereby scribing of the glass substrate is possible without being affected by the presence or thickness of a deposited film formed thereon and without scratching the deposited film. To treat a glass substrate having a deposited film, such as a thin film or resin film, formed on one surface thereof, there are provided a shaving device, which is a blade that removes strip-shaped portions of the deposited film to expose strip-shaped regions on the glass substrate, and a wheel cutter (14a) that forms scribed lines along the strip-shaped regions exposed on the glass substrate. The glass substrate is cut apart along the scribed lines.

  • Patent number: 7889309
    Abstract: A manufacturing method of a liquid crystal display panel includes: a sealant arranging step of arranging a sealant on a main surface of one of or each of two substrates to be bonded to each other; a liquid crystal dropping step of dropping liquid crystal on one of the two substrates; and a bonding step of bonding the two substrates to each other, wherein the method further includes: to be performed prior to the liquid crystal dropping step, a deaerating step of arranging in a pressure-reduced atmosphere at least a substrate on which the liquid crystal is to be dropped out of the two substrates; and, to be performed prior to the bonding step, a releasing step of releasing the pressure-reduced atmosphere by an inert gas.

  • Patent number: 7868964
    Abstract: A liquid crystal display panel manufacturing apparatus is provided with a stage for fixing a substrate having an optical film adhered to at least one of surfaces of the substrate. The stage has a suction hole for attracting the substrate by suction. The stage has an interposition member located around a region provided with the suction hole, and the interposition member has a closed frame-like form in a plan view. A display panel manufacturing apparatus that can stably fix the substrate is provided.
