Parallel interconnection of neighboring space-qualified solar cells via a common back plane

摘要

A solar cell assembly for space application comprising a plurality of space-qualified solar cells and a support, the support comprising a conductive layer. The conductive layer is divided into a first conductive portion and a second conductive portion. Each space-qualified solar cell of the plurality of space-qualified solar cells comprising a front surface, a rear surface, and a first contact in correspondence with the rear surface. Each one of the plurality of space-qualified solar cells is placed on the first conductive portion with the first contact electrically connected to the first conductive portion so that the space-qualified solar cells are connected in parallel through the first conductive portion. A second contact of each space-qualified solar cell can be connected to the second conductive portion. The two conductive portions serve as bus bars of the space-qualified solar cell assembly.
