Verfahren zur Herstellung eines photovoltaischen Solargenerators

摘要

Prodn. of a photovoltaic solar generator, consisting of solar cells which have contact elements extending across their width and which form a shingled assembly embedded in hot melt adhesive foils between a support and a cover, comprises (a) coating the contact elements with a contacting paste which, on low temp. vacuum treatment, produces an electrical connection between the overlying contact elements of adjacent cells; (b) assembling the cells on an adhesive foil on the support so that adjacent contact elements are loosely bonded together by the paste; (c) electrically connecting the edge regions of the shingled assemblies and providing electrical terminals; (d) covering the assemblies with a second adhesive foil and a cover; and (e) subjecting to low temp. vacuum treatment to produce an electrically conductive bond between the contact elements and, immediately afterwards, to cause mechanically rigid bonding of the support, the adhesive foils, the solar cells and the cover to obtain a solar cell, generator. ADVANTAGE - The process has a reduced number of steps and allows prodn. of curved or domed generators.
