Solar cell array interconnects

Title: Solar cell array interconnects

Electrical interconnects are disclosed for solar cells or other electronic components using a silver-silicone paste or a lead-tin (Pb-Sn) no-clean fluxless solder cream, whereby the high breakage of thin (<6 mil thick) solar cells using conventional solder interconnect is eliminated. The interconnects of this invention employs copper strips which are secured to the solar cells by a silver-silicone conductive paste which can be used at room temperature, or by a Pb-Sn solder cream which eliminates undesired residue on the active surfaces of the solar cells. Electrical testing using the interconnects of this invention has shown that no degradation of the interconnects developed under high current testing, while providing a very low contact resistance value. 4 figs.

Cascade solar cell having conductive interconnects

Patent Borden, Peter G. ; Saxena, Ram R.

Direct ohmic contact between the cells in an epitaxially grown cascade solar cell is obtained by means of conductive interconnects formed through grooves etched intermittently in the upper cell. The base of the upper cell is directly connected by the conductive interconnects to the emitter of the bottom cell. The conductive interconnects preferably terminate on a ledge formed in the base of the upper cell.

Combined photovoltaic-thermoelectric solar cell and solar cell array

Patent - in OSTI.gov collection Ellion, M.E.

A solar cell array is described comprising: electrically connected gallium arsenide solar cells; means for imposing a thermal gradient across the thickness of each of the solar cells greater than that normally experienced by gallium arsenide solar cells exposed to direct sunlight, a hot face of the solar cells being at a temperature greater than a cool face thereof; and face electrode means in contact with the solar cells, including a hot junction electrode producing a high thermoelectric potential at the hot face and a cool junction electrode producing a low thermoelectric potential at the cool face of each ofmore » the solar cells.« less

Method of fabricating a solar cell array

Patent Lazzery, Angelo G. ; Crouthamel, Marvin S. ; Coyle, Peter J.

A first set of pre-tabbed solar cells are assembled in a predetermined array with at least part of each tab facing upward, each tab being fixed to a bonding pad on one cell and abutting a bonding pad on an adjacent cell. The cells are held in place with a first vacuum support. The array is then inverted onto a second vacuum support which holds the tabs firmly against the cell pads they abut. The cells are exposed to radiation to melt and reflow the solder pads for bonding the tab portions not already fixed to bonding pads to thesemore » pads.« less
