Embodiment Construction

[0016] as attached figure 1 And attached figure 2 A flexible light-transmitting photovoltaic module is shown, which includes the following layer structure: the bottom layer is a transparent TPT film. The TPT can be replaced by other non-glass light-transmitting materials such as PET, TPE, KPK; the top layer is a transparent TPT film; the middle layer is two A layer of EVA sealant film, and a crystalline silicon photovoltaic cell is sandwiched between the two layers of EVA sealant film.

[0017] The multilayer structure is prepared by the following method:

[0018] 1. Sorting of crystalline silicon solar cells: Before assembling crystalline silicon solar cells, power screening should be carried out to ensure the consistency of the current, so that the working current of each single crystalline silicon cell is 4.5A, the working voltage is 0.5V, and the thickness 0.2mm, the appearance is not damaged, and the color is uniform.

[0019] 2. Cutting of EVA sealing film: The cutt...
