SEMIFINISHED PRODUCT OF A MULTI-JUNCTION SOLAR CELL AND METHOD FOR PRODUCING A MULTI-JUNCTION SOLAR CELL

摘要

The semi-finished product has two solar cell semiconductor portions (40,50) that form an integral connection with a tunnel diode. The semiconductor portions are formed with different bandgaps. A sacrificial layer (30) is formed between the solar cell semiconductor portions on a substrate. The substrate is removed under destruction of the sacrificial layer. An independent claim is included for method for manufacturing multi-shed solar cell.
