Abstract:
1. A monolithic, multijunction solar cell, comprising: a first photovoltaic sub-cell; a tunnel junction provided over the first photovoltaic sub-cell, the tunnel junction including a single crystal II-VI semiconductor material layer having a band gap greater than 1.5 eV; and a second photovoltaic sub-cell provided over the tunnel junction, the second photovoltaic sub-cell including a multi-crystalline group II-VI semiconductor material base comprised of CdSe and a multi-crystalline group II-VI semiconductor material emitter having band gaps greater than 1.5 eV, wherein light incident on the monolithic, multijunction solar cell is received by the second photovoltaic sub-cell before the first photovoltaic sub-cell.
