Method for manufacturing photovoltaic module formed on corrugated-sheet building material

A method for manufacturing a photovoltaic module formed on a corrugated-sheet building material, the method comprising the steps of:

• (step 1) shaping a board to function as a base board in a manner that the board thus shaped takes on a corrugated-sheet shape and therefore not only has thereon alternating grooves and ridges but also a processing surface defined between a said groove and an adjacent said ridge;
• (step 2) forming a photovoltaic module on the processing surface of the base board by stacking, including putting a bottom adhesive film layer on the processing surface of the base board, putting a photovoltaic layer on the bottom adhesive film layer, putting a top adhesive film layer on the photovoltaic layer, and finally putting a condensing film layer on the top adhesive film layer;
• (step 3) rolling the photovoltaic module and the base board against each other at 130˜480° C. to effectuate engagement therebetween;
• and
• (step 4) performing lamination on the photovoltaic module and the base board within a hermetically sealed space at 140˜170° C. and 2˜10 kg/cm2 for 5˜10 minutes.
