Semitransparent flexible thin film solar cells and modules

A method of manufacturing a semitransparent thin film solar cell structure stack, comprising:

• forming a solar cell structure stack wherein the solar cell structure stack includes a flexible foil substrate, a contact layer formed over the flexible foil substrate, a Group IBIIIAVIA absorber layer formed over the contact layer and a transparent conductive layer formed over the Group IBIIIAVIA absorber layer;
• and
• mechanically forming a plurality of openings through the solar cell structure stack to create a hole pattern in the solar cell structure stack, each of the openings in the hole pattern extending through the transparent conductive layer, the Group IBIIIAIVA absorber layer, the contact layer and the flexible foil substrate, thereby making the semitransparent solar cell structure stack.
