Abstract: Solar cells, particularly GaAs/GaSb tandem solar cells, are mechanically and electrically connected in the form of a string using a flexible circuit tape and mounted in optical alignment with solar energy concentrators in a module. A heat spreader body is attached to each cell unit as part of a heat sink and the cells are precisely positioned to provide optical alignment. The flexible circuit tape is formed by conductive strips sandwiched between layers of polymer dielectric tape and provided with tabs at predefined holes in the tape for bonding to current carrying surfaces of concentrated sunlight tandem solar cell units.

Abstract: Solar cells, particularly GaAs/GaSb tandem solar cells, are mounted on a honeycomb light weight panel in optical alignment with solar energy concentrators mounted on a front panel side. The cells are mounted on metallized surfaces of the heat spreader that is attached to a panel wall rear panel side. A circuit carrier has conductors which are bonded to metallization islands that are on one side only of the heat spreader. The circuit carrier is adhered to the rear panel side.
