Abstract

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.
