Photovoltaic Modules Manufactured Using Monolithic Module Assembly Techniques
First Claim
1. A photovoltaic module comprising:
- a plurality of back-contact solar cells;
a flexible backsheet;
a patterned metallization on said backsheet;
an insulating material disposed between said patterned metallization and said solar cells, said insulating material patterned so as to enable electrical contact between said patterned metallization and said solar cells in desired locations; and
a plurality of busses in electrical contact with said patterned metallization.

Abstract
Photovoltaic modules comprising back-contact solar cells manufactured using monolithic module assembly techniques comprising a flexible circuit comprising a back sheet and a patterned metallization. The module may comprise busses in electrical contact with the patterned metallization to extract the current. The module may alternatively comprise multilevel metallizations. Interlayer dielectric comprising islands or dots relieves stresses due to thermal mismatch. The use of multiple cord plates enables flexible circuit layouts, thus optimizing the module. The modules preferably comprise a thermoplastic encapsulant and/or hybrid adhesive/solder materials. An ultrathin moisture barrier enables roll-to-roll processing.
