Solar cell having conductive contacts in alignment with recast signatures

A solar cell comprising:

• a first dielectric layer disposed on a silicon substrate;
• a poly-crystalline silicon layer disposed on the first dielectric layer, the poly-crystalline silicon layer having a doped region and a recast signature in the doped region;
• a second dielectric layer above the poly-crystalline silicon layer;
• and
• a plurality of conductive contacts through the second dielectric layer, a conductive contact of the plurality of conductive contacts being in alignment with the recast signature.

A solar cell comprising:

• a first dielectric layer disposed on a silicon substrate;
• a poly-crystalline silicon layer disposed on the first dielectric layer, the poly-crystalline silicon layer having a doped region and a plurality of recast signatures;
• a dielectric material stack disposed on the poly-crystalline silicon layer;
• and
• a plurality of conductive contacts through the dielectric material stack, each conductive contact of the plurality of conductive contacts being in alignment with a recast signature of the plurality of recast signatures.
