[0024] The present invention also discloses a method for preparing the aforementioned transparent confluence belt, which includes the following steps:

[0025] Choline chloride was dried under vacuum at 60°C for 24 hours to become anhydrous choline chloride; anhydrous choline chloride was mixed with maleic acid at a molar ratio of 2:1, and then the mixture was heated and stirred at 90°C for two hour to form a colorless prepolymer A; then mix anhydrous choline chloride and acrylamide at a molar ratio of 1:2, then heat and stir the mixture at 90°C to form a colorless prepolymer 2; then mix anhydrous Choline chloride, maleic acid and acrylamide were mixed at a molar ratio of 2:1:2, and the mixture was heated and stirred at 90°C to form a colorless prepolymer C. Then 1wt% of the cross-linking agent—diethylene glycol diacrylate and 1wt% of the photoinitiator—2-hydroxy-4'-(2-hydroxyethoxy)-2-methylpropiophenone were mixed with the pre- Polymer A, prepolymer B, and prepolymer C were...

Embodiment 1

[0033] The first embodiment of the method for preparing a photovoltaic module of the present invention, taking the preparation of a translucent perovskite photovoltaic module as an example, includes the following steps:

[0034] Step 11. Prepare a transparent slurry for the transparent confluence belt according to the aforementioned method.
