Problems solved by technology

However, the three-dimensional model of the curved surface skin is complex, and there is no definite rule for the collection of sunlight. Therefore, there is no relatively mature technology for the production and construction of curved surface building integrated photovoltaic materials at home and abroad.

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.

Description

technical field [0001] The invention relates to the field of building technology, and more specifically, relates to a method for manufacturing a curved thin-film photovoltaic building skin and a curved thin-film photovoltaic building skin module. Background technique [0002] As a clean renewable energy, solar energy is abundant in reserves, easy to collect, and very valuable in application. In order to make full use of solar energy resources and effectively alleviate the pressure of building energy consumption, how to effectively integrate photovoltaic materials into the building skin to make it a building material that can realize power output, so as to realize building integration of photovoltaics and truly realize energy generation in buildings It will be of great research significance. [0003] At present, thin-film photovoltaics are mainly flat-panel photovoltaics. However, with the increasing complexity of architectural forms, curved architectural skins are widely u...
