Abstract

This invention belongs to the field of photovoltaic module technology, specifically relating to a method for preparing a lightweight photovoltaic module and its application. The preparation method includes the following steps: S1, sequentially laying a front encapsulation plate, a first encapsulating film, a solar cell, a second encapsulating film, and a rear encapsulation plate to obtain a laminate; S2, performing a lamination process on the laminate to obtain the lightweight photovoltaic module; the lamination process includes sequentially placing the laminate in the first and second chambers of a laminator for lamination; the lamination temperature T1 of the first chamber is lower than the lamination temperature T2 of the second chamber, and satisfies: 30℃≤T2-T1≤50℃. The lightweight photovoltaic module provided by this invention has high initial power, good weather resistance, aging resistance, and bending resistance, and has excellent application prospects in photovoltaic power generation equipment.
