摘要：
A multijunction solar cell includes a base substrate comprising a Group IV semiconductor and a dopant of a first carrier type. A patterned emitter is formed at a first surface of the base substrate. The patterned emitter comprises a plurality of well regions doped with a dopant of a second carrier type in the Group IV semiconductor. The base substrate including the patterned emitter form a first solar subcell. The multijunction solar cell further comprises an upper structure comprising one or more additional solar subcells over the first solar subcell. A method of making a multijunction solar cell is also described.
