ABSTRACT:
A two-terminal voltage or current matched solar cell has up to four photovoltaically active junctions which efficiently convert solar radiation into electricity. The solar cell comprises GaInP, GaAs, and GaInAsP, and in the four junction case, GaInAs is used as well. The invention allows the solar spectrum to be converted into electricity more efficiently than previously.
