PROCESS FOR MANUFACTURING A MULTI-JUNCTION STRUCTURE FOR A PHOTOVOLTAIC CELL |
摘要 |
Process for manufacturing a multi-junction structure for a photovoltaic cell. The process comprises steps consisting in: a) providing a first donor substrate (1) comprising a first carrier substrate (3) and a first seed layer (4) comprising a first material; b) providing a second donor substrate (5) comprising a second carrier substrate (6) and a second layer (7) comprising a second material different from the first material; c) bringing the first seed layer (4) and the second layer (7) into contact so as to obtain a direct bond between the first seed layer (4) and the second layer (7) with a view to forming the bonding interface (9); d) removing the first carrier substrate (3) so as to expose the first seed layer (4); and e) epitaxially growing at least one first junction (11) on the first seed layer (4). |
