An interconnect, having some length, that reliably connects two conductors separated by the length of the interconnect when the connection is made but in which one length if unstressed would change relative to the other in operation. The interconnect comprises a base element an intermediate element and a top element. Each element is rectangular and formed of a conducting material and has opposed ends. The elements are arranged in a generally Z-shape with the base element having one end adapted to be connected to one conductor. The top element has one end adapted to be connected to another conductor and the intermediate element has its ends disposed against the other end of the base and the top element. Brazes mechanically and electrically interconnect the intermediate element to the base and the top elements proximate the corresponding ends of the elements. When the respective ends of the base and the top elements are connected to the conductors, an electrical connection is formed therebetween, and when the conductors are relatively moved or the interconnect elements change length the elements accommodate the changes and the associated compression and tension forces in such a way that the interconnect does not mechanically fatigue.

Zee electrical interconnect

A solar panel in which the bus-and-interconnect structures are visually masked, to improve not only aesthetics but also the operational characteristics of the panel. A transparent superstrate for the panel has on a surface juxtaposed to the radiation-receiving surfaces of the cells a pattern masking material just sufficient, with manufacturing tolerances, to mask the generally non-symmetrical interconnect structure in a substantially more uniform, symmetrical manner. The masking material may be matte-finish (paint) or highly reflective (a metallic deposit), and in either case may be applied by the same process (e.g., silk screen). The reflective mask structure inhibits heat build-up in the panel; and the matte-finish mask structure is generally unobtrusive and aesthetically pleasing, as required for example, in vehicular applications. A redundant bus structure yields surprisingly compact interconnects, with increased versatility in arrangement of grid patterns of collector electrodes, and is highly compatible with the masking structures and techniques.

Solar panel with interconnects and masking structure, and method

An interconnect for electrically connecting adjacent solar cells disposed in a solar cell array is disclosed. The interconnect is comprised of three parts: an elongated stress relief part disposed substantially parallel to adjacent side edges of the solar cells which are electrically connected by the interconnect; a first connecting part joined to a first end portion of the stress relief part and to the electrical contact of the first solar cell; and a second connecting part joined to the opposite end portion of the stress relief part and to the electrical contact of the adjacent solar cell. In this manner, stress induced in the interconnect as a result of thermal cycling of the solar cells electrically connected by the interconnect is significantly reduced as compared to prior art configurations to thereby increase the survivability and expected life of the interconnect. In addition, the removal and replacement of the connected solar cells is facilitated.
