    Abstract: A photovoltaic module comprises electrically interconnected and mutually spaced photovoltaic cells that are encapsulated by a light-transmitting encapsulant between a light-transparent front cover and a back cover, with the back cover sheet being an ionomer/nylon alloy embossed with V-shaped grooves running in at least two directions and coated with a light reflecting medium so as to provide light-reflecting facets that are aligned with the spaces between adjacent cells and oriented so as to reflect light falling in those spaces back toward said transparent front cover for further internal reflection onto the solar cells, whereby substantially all of the reflected light will be internally reflected from said cover sheet back to the photovoltaic cells, thereby increasing the current output of the module. The internal reflector improves power output by as much as 67%.

  • Patent number: 7019207
    Abstract: Known methods of producing large-surface integrated thin-film solar modules with an amorphous, poly- or microcrystalline absorber layer always comprise division and conversion structuring processes which can cause instabilities in the structuring and which are relatively expensive. According to the inventive method which can be used to fabricate substrate solar cells and superstrate solar cells, the mask which is used provides for structuring itself during the deposition of layers for the rear electrode and the absorber layer through its geometrical form. The use of a mask which can be reused as an independent element after use in this method allows for a relatively free range of possible geometric forms. This also makes possible applications inside and outside of buildings, including in the area of a window, from an esthetic and informal point of view.

  • Patent number: 6607935
    Abstract: An array substrate for use in an X-ray sensing device is fabricated using an etching stopper that enables good control of the etching process and that prevents over-etch of drain electrodes and second capacitor electrodes while forming contact holes and a cutting furrow. The etching stopper is located in a tiling portion that is utilized for tiling substrates to form a large-sized X-ray detector. During fabrication, gate lines can have gate-protruded portions located near the etching stopper, and the etching stopper can have stopper-protruded portions near the gate lines. The stopper-protruded portions electrically connect to the gate-protruded portions through gate line contact holes such that the etching stopper and the gate lines have equipotentials. This can reduce static electricity damage.

    Abstract: A machine for the automated assembly of wafers such as solar cells into strings, comprising a control system, a cell loader with wafer inspection station, a cell tab loader, a string assembly station, and a platen with adjacent pairs of individual cell, opposing edge grippers having multiple sets of vertically operable pincer action fingers for holding cells in string alignment during soldering. The string assembly station has a cooperating cell support and tab tail support mechanism providing for a tab tail hand off from one to the other with a platen indexing movements of cell pitch distance. The platen moves from the string assembly station through a soldering station consisting of a preheat, soldering, and cooling zones spaced a cell pitch distance apart. A string unloader moves completed strings through a string inspection station placing strings in a good or bad string holding area.

  • Publication number: 20030121542
    Abstract: Known methods of producing large-surface integrated thin-film solar modules with an amorphous, poly- or microcrystalline absorber layer always comprise division and conversion structuring processes which can cause instabilities in the structuring and which are relatively expensive. According to the inventive method which can be used to fabricate substrate solar cells (116) and superstrate solar cells, the mask (100) which is used provides for structuring itself during the deposition of layers for the rear electrode (106) and the absorber layer (11) through its geometrical form. The use of a mask (110) which can be reused as an independent element after use in this method allows for a relatively free range of possible geometric forms. This also makes possible applications inside and outside of buildings, including in the area of a window, from an esthetic and informal point of view.

  • Publication number: 20030106579
    Abstract: A solar cell array is provided having a lattice or matrix structure such that no two solar cell devices are connected purely in series or purely in parallel. Accordingly, if a single solar cell device fails, there is an alternate path by which the output power of all other solar cell devices may contribute to the total output power of the solar cell array. Also, the power output of the entire array is much less sensitive to a low voltage or current for a single solar cell device than in a conventional array where devices are connected in series and in parallel. Beneficially, current setting devices, such as resistors, are provided for better matching the voltages and currents within the array, although in some applications, the resistors can be eliminated, or set to zero. The lattice or matrix structures may be extended in one, two, and three-dimensional patterns.

    Abstract: A TFT array is formed on a glass substrate (step P1). A surface protection layer is formed on the glass substrate so as to cover the TFT array (step P2). The glass substrate is divided to form active matrix substrates with the surface protection layer being provided (step P3). The divided active matrix substrate is chamfered along its edges (step P4). The surface protection layer is removed from the active matrix substrate (step P5). An X-ray conductive layer is formed on the TFT array where the surface protection layer has been removed (step P6). By these steps, pollutants produced during the division and chamfering of the glass substrate are prevented from polluting the TFT array and the X-ray conductive layer, and the active element array and the semiconductor layer is prevented from deteriorating in terms of performance in manufacturing process for a two-dimensional image detector.
