PROBLEM TO BE SOLVED: To provide a multijunction solar cell with a low band gap absorbing layer in a middle cell, and a method of manufacturing the same.SOLUTION: A multijunction photovoltaic cell comprises: a top cell; a second cell disposed immediately adjacent to the top cell and producing a first photo-generated current; and including a sequence of first and second different semiconductor layers with different lattice constants; and a lower subcell disposed immediately adjacent to the second subcell and producing a second photo-generated current substantially equal in amount to the first photo-generated current density. |
