摘要:
A coating substrate containing an aluminum or aluminum rolled alloy product for thin-film coatings for producing electronic components. The coating substrate prevents the interdiffusion of substrate elements and thin-film coating elements and enables the thin-film coatings to grow completely over irregularities. The local irregularities on the substrate surface to be coated, which have a maximum extension, measured vertically to the substrate surface, of less than 10 um and than 0.1 um, are such that the flanks of the local irregularities can be exposed to material deposition impinging on the substrate surface in a perpendicular manner.
摘要:
A photovoltaic cell (10) having a semiconductor substrate (11), a front passivation layer (12) arranged on the substrate, an emitter layer (14) having a first conductivity type (p or n), a front transparent conductive layer (15), a rear passivation layer (17) deposited on a rear surface of the substrate, a rear layer (18) producing a back surface field having a second conductivity type (n or p) opposite to the first conductivity type, as well as a reflecting element (19) comprised of a transparent conductive layer (20), an adhesion layer (21), and a reflecting layer (22). The disclosed cell has a substantially high efficiency a substantially low fabrication cost and is used in solar cells.
摘要:
A method for producing a membrane device by providing a substrate (24), adding a liquid (16) thereon, and covering the liquid (16) and at least one substrate portion bearing the liquid (16) with a homogenous continuous thin film (18) by means of a low-pressure deposition process. The film is made of a plastic material and forms a membrane.
