Claim 0:
1. A plurality of thin film multi-junction solar cells free of a six inch substrate on which the plurality of solar cells were formed, each comprising:
a first active layer forming a first junction;
a second active layer forming a second junction;
a third active layer forming a third junction, at least one of the first active layer, second active layer or third active layer having a lattice mismatch with the six inch substrate on which the active layers were grown; and
a support backing layer formed directly on the first active layer of each of the plurality of solar cells providing a common support for the plurality of solar cells, the support backing layer having an area corresponding to the six inch substrate, the support backing layer comprising a plurality of metal sublayers including a main support sublayer, the support backing layer providing structural support for each of the plurality of solar cells in an absence of the six inch substrate, wherein each of the plurality of thin film multi-junction solar cells is flexible.
