Thin film solar cell module including series connected cells formed on a flexible substrate by using lithography

A solar cell module comprising:

• a flexible substrate;
• a rear side metallization layer on said flexible substrate and having a plurality of first isolation trenches therein;
• a semiconductor junction layer on said rear side metallization layer and laterally divided into a plurality of semiconductor regions by a plurality of second isolation trenches therein;
• and
• a transparent front side metallization layer on the plurality of semiconductor regions and having a plurality of third isolation trenches therein so as to define a plurality of series-connected solar cells.
