Abstract

The invention discloses a manufacture method of a curved surface film photovoltaic building surface and an adopted surface module, and aims at providing a manufacture method capable of reducing the construction difficulty and improving the construction efficiency and a surface module. The manufacture method comprises the following steps: designing an initial curved surface model; performing optimization design by taking the maximum solar irradiation absorbing amount as a target, so as to obtain an optimized curved surface model; dividing the optimized curved surface into a plurality of modules; printing a hard curved surface back plate according to a 3D printing technology according to patterns of divided modules, and sequentially overlapping and fixing a first flexible film clamping piece, a flexible film solar cell, a second flexible film clamping piece and a flexible waterproof transparent plastic film on the printed hard curved surface back plate, and packaging an edge; performingsite mounting on each finished product surface module; finally splicing adjacent modules, so as to accomplish the construction of a complete building surface facade. The method greatly reduces the site mounting difficulty, and improves the construction efficiency.
