Development of Mechanically-Stacked Multijunction Solar Cell for Concentrator Applications. Final Report

摘要

Development of a mechanically-stacked, multijunction solar cell is described. The cell uses a thin, high-bandgap cell bonded to the top of a silicon cell. Two electrical leads are brought out from each cell in the stack so that the cells may be operated electrically in parallel while they are optically in series. This report discusses modeling and packaging of the cascaded cells. It also describes a process for making a thin, high-bandgap AlGaAs solar cell. (ERA citation 09:018357)
