Cascade solar cell having conductive interconnects
Patent
·
OSTI ID:864372
- Menlo Park, CA
- Saratoga, CA
Direct ohmic contact between the cells in an epitaxially grown cascade solar cell is obtained by means of conductive interconnects formed through grooves etched intermittently in the upper cell. The base of the upper cell is directly connected by the conductive interconnects to the emitter of the bottom cell. The conductive interconnects preferably terminate on a ledge formed in the base of the upper cell.
