AI Technical Summary

Technical Problem

Existing photovoltaic panels are difficult to manufacture according to customized sizes and three-dimensional shapes. Flexible thin-film PV cells have limited flexibility, require high positioning accuracy during manufacturing, and are complex to assemble.

Method used

Multiple flexible photovoltaic elements are used, and rear-accessible terminals are formed by folding the rear surface backward and protruding the side, avoiding through-hole electrical connections. The conductive wiring elements and photovoltaic elements are encapsulated with sealant to form a sealant cover layer to fix the position and conduct the interconnection, simplifying the manufacturing process.

Benefits of technology

It simplifies the manufacturing of flexible photovoltaic panels, reduces positioning accuracy requirements, improves assembly efficiency, and enables the formation of three-dimensional photovoltaic panels according to predetermined patterns.

Abstract

The present disclosure relates to a 3D formable photovoltaic solar panel, in particular to a semi-finished free-formable photovoltaic module for a 3D formed solar panel and a method of manufacturing the same. The semi-finished free-formable photovoltaic module comprises: a plurality of laterally spaced rear contactable flexible photovoltaic elements; a plurality of flexible conductive wiring elements forming conductive interconnections between the flexible photovoltaic elements, each wiring element having an overlap with a respective rear terminal of an adjacent flexible photovoltaic element; and a sealant cover layer, wherein the sealant cover layer substantially fixes the overlap of the wiring elements relative to the respective rear terminals.
