Embodiment Construction

[0089] The process discussed below involves the use of elongated solar cells to form two products, elongated solar cell rafts for incorporation in a stationary collector solar power module; and elongated solar cells for application in collector reception Welded raft. The processes discussed in the formation of these two products can also be applied to the formation of flat panel solar cell welding rafts and flat panel solar cell welding boats with simple dimensional changes to the equipment used. The same provisions for internal interchange between the separation, handling and assembly methods, processes and products of flat solar cells and strip solar cells are also used for rafts, grid rafts and boats.

[0090] International patent application PCT / AU2005 / 001193 discusses a process for forming assemblies or submodules for elongated substrates. Such submodules facilitate the handling of elongated substrates that have been assembled into larger modules. In particular, such su...

Abstract

A solar cell interconnection process for forming a solar cell sub-module for a photovoltaic device, the process including the steps of mounting a plurality of elongate solar cells (101) on a crossbeam (102) on patches of solderable material (201) which is used to maintain solder in position, the elongate solar cells being in a substantially longitudinally parallel and generally co-planar configuration: and establishing one or more conductive pathways (204) extending between adjacent cells to electrically interconnect the elongate solar cells via the contacts (202, 203): wherein the one or more conductive pathways are established by wave soldering.

Description

technical field [0001] The present invention relates to a solar cell interconnection process for interconnecting elongated solar cells to form solar cell submodules of photovoltaic devices. Background technique [0002] In this specification, the term "elongated solar cell" refers to a solar cell, usually parallelepiped-shaped and with a high aspect ratio, whose length l is much larger (usually tens to hundreds of times larger) than its width w. In addition, the width of an elongated solar cell is much larger than its thickness t (typically four to one hundred times larger). The length and width of the solar cell define the maximum usable effective surface area for generating electrical energy, while the length and thickness of the solar cell define the optically inactive surface or "edge" of the cell. A typical elongated solar cell is 10-120 mm long, 0.5-5 mm wide, and 15-400 microns thick. [0003] Elongated solar cells can be produced by the process described in: "HighV...
