摘要:
The present invention relates to a thin-film solar cell and a process for producing it, where the rear-side layer structure of the thin-film solar cell has a multilayer structure comprising a metallic bonding layer, a transition layer and an Ag-containing reflector layer and displays a high degree of reflection and good adhesion of the layer system.
摘要:
For fastening the contact strip (8) to the back electrode layer (4) of a photovoltaic module, the back electrode layer (4) is provided on its outer side with a tin-, copper- and/or silver-containing contact layer (12). Subsequently the contact strip (8) provided with solder (17) on the joining surface is connected to the back electrode layer (4) by soldering. The contact layer (12) causes good adhesion of the back surface encapsulation material (13) to be obtained. A barrier layer (11) prevents alloying of the tin-solder with the layers (9, 10) of the back electrode layer (4).
摘要:
A photovoltaic module has on a transparent substrate (1) a transparent front electrode layer (2), a semiconductor layer (3) and a back electrode layer (4). The back electrode layer (4) has a silver layer (7) and between the silver layer (7) and the semiconductor layer (3) an interlayer (5) consisting of a doped semiconductor. A copper layer (6) is provided between the silver layer (7) and the interlayer (5).
摘要:
For producing a photovoltaic module (1), the front electrode layer (3), the semi-conductor layer (4) and the back electrode layer (5) are patterned by separating lines (6, 7, 8) to form series-connected cells (C1, C2, . . . Cn, Cn+1). The patterning of the front electrode layer (3) and of the semiconductor layer (4) is done with a laser (13) emitting infrared radiation. During patterning of the semiconductor layer (4) the power of the laser (13) is so reduced that the front electrode layer (3) is not damaged.
摘要:
For making a glass panel (1) coated by chemical vapour deposition with an electrically conductive transparent metal oxide (3) for use as a starting material for fabricating a photovoltaic module, chemical vapour deposition of said electrically conductive transparent metal oxide (3) onto glass panel (1) is performed at a coating temperature not more than 50° C. lower than the transition temperature of the glass.
摘要:
For the purpose of attaching the frame (1) to the tank (6), the tank (6) has on the outer side niches (18) which are widened inwardly. Opposite each of the niches (18) the frame (1) has an opening (4). Connecting members (9) are each snapped into an opening (4) and engage at an inner end into a niche (18). Wedges or pins (10) driven into a recess (13) fix a tenon (17) engaging the niche (18) from behind. Simple and automatable operations suffice for the installation.

摘要:
The mounting frame has for attachment of sanitary fixtures two attachment plates (7) provided with holes (9) arranged in a predetermined pattern. Base nuts (11) with threaded bolts (10) are inserted detachably into the holes (9). To attach a sanitary fixture to the threaded bolts (10), a suitable pair of holes is chosen. A vertically adjustable flush pipe (2) can be fixed in position at the desired height by stop cams (5), which are also arranged in a predetermined one-dimensional pattern. A vertically adjustable discharge elbow (12) is also mounted on the frame (20).
