MULTI-JUNCTION SOLAR CELL WITH SELF COMPENSATING SUB-CELLS

摘要

A semiconductor device is disclosed, and includes a first sub-cell generating a first electrical current, a second sub-cell generating a second electrical current, and at least one power converter. The first sub-cell and the second sub-cell are electrically coupled to one another in series. The power converter is electrically coupled to both the first sub-cell and the second sub-cell. The power converter introduces a compensating current into at least one of the first sub-cell and the second sub-cell to balance the first electrical current and the second electrical current to be substantially equal to one another.
