| 摘要 |
The invention relates to a solar cell including a stack of at least two subcells (23, 25), a tunnel diode (27) comprising first and second stacked layers (29, 31) which are highly doped with opposite conductivity types, said tunnel diode being placed between two adjacent subcells; a first electrode (35) and a second electrode (39) in contact with one (28) and the other (22), respectively, of the surfaces at the ends of the stack; and for at least one tunnel diode (27), a third electrode (41) and a fourth electrode (43) in electrical contact with the first layer (31) and with the second layer (29), respectively, of the tunnel diode. |
