Wirth, HarryHarryWirth2022-03-082022-03-082006https://publica.fraunhofer.de/handle/publica/307574(A1) Vorliegende Erfindung betrifft einen Zellverbinder (ZV) zur elektrischen Kontaktierung von flaechigen Stromquellen, wobei der Zellverbinder lediglich bereichsweise mit der Stromquelle elektrisch kontaktierbar ist. Der Zellverbinder besteht dabei aus mindestens einer elektrisch leitfaehigen Schicht, die als Transitbereich gestaltet ist, und ueber Kontaktbereiche, die bezueglich der Gesamtflaeche des Transitbereiches lediglich einen Bruchteil ausmachen, mit der Stromquelle kontaktiert ist.DE 102006049603 A1 UPAB: 20080514 NOVELTY - The connector (1) has an electrical conductive layer (3), which exhibits a contact area (7) for contacting with each of solar cells (2) in an area wise manner, and a non-contactable area forming a transit-area for guiding current. The contact area provided per solar cells is arranged in a boundary region of the connector, which is designed with a variable cross section. The electrical conductive layer exhibits a recess (5) for texturizing and consists of silver, aluminium and copper, where the recess is designed in a quadratic, rectangular, oval and/or circular shape. USE - Cell connector for use as front contacts, rear side contacts and/or side contacts for electrically contacting of planar power sources e.g. solar cells and fuel cells (claimed), with a discharging point in a boundary region. ADVANTAGE - The connector is designed such that a better lowering of mechanical stress at discharging points of the power source is achieved without negative influence on the power conductivity of the power source. The design of the connector with variable cross section saves the usage of the conductive material.de621697patent102006049603
