The present disclosure relates to a method for manufacturing thin, efficient, and aesthetically pleasing PV modules having masked or non-shiny interconnects. The method involves a step of applying a masking material over interconnects that are used for electrically connecting PV cells associated with the PV module. The masking material is in form or a strip or ribbon or paste adapted to be attached or applied over the interconnects, which saves the material and also restricts shining of the interconnects. Further, a clear glass superstrate is attached on top of the masked PV cells, and another glass substrate or polymer backsheet is attached to bottom of the masked PV cells. The masking material used is a chemical or radiation stable material, same as the material used for manufacturing the PV module, which restricts deterioration due to chemical reactions or UV light exposure.
