Title:
MULTIJUNCTION SOLAR CELL AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2009076921
Kind Code:
A
Abstract:
To provide an improved multijunction solar cell and a manufacturing method thereof.
A multijunction solar cell includes a first solar subcell having a first band gap; a second solar subcell disposed over the first subcell and having a second band gap smaller than the first band gap; a grading interlayer disposed over the second subcell and having a third band gap greater than the second band gap; a third solar subcell disposed over the interlayer that is lattice mis-matched with respect to the middle subcell and having a fourth band gap smaller than the second band gap; and either a thin (approximately 2-6 mil) substrate and/or a rigid coverglass supporting the first, second, and third solar subcells.
