Under the existing technical conditions, thin-film solar cells are often laid on the surface of buildings. During the laying process, fixed installation is required, and the amount of work is relatively large. The market urgently needs a new type of power generation cable that can quickly install solar cells, and at the same time, can be quickly moved and installed, and is easy to clean and maintain.

When moving or cleaning, the The new power generation cable is wound and stored in a cable style, and at the same time, the new power generation cable can be convergingly connected through the junction box 4 arranged at the inner port of the pipe wall 3 .

Further, the thin-film solar cell layer 2 covers half of the outer surface area of the tube wall 3 .

Covering one-half of the outer surface area of the tube wall 3 can effectively cover the light-receiving surface of the flexible cylindrical tube wall 3 , which is economical.

Further, the encapsulation layer 1 is an ETFE film encapsulation layer with high light transmittance.

The ETFE film encapsulation layer, that is, ethylene-tetrafluoroethylene copolymer, has excellent light transmission and elasticity, and its unique anti-adhesion surface makes it highly anti-fouling and easy to clean. Usually, rainwater can remove major dirt.

Further, the encapsulation layer 1 is covered and adhered to the outer surface of the thin-film solar cell layer 2 through an EVA film.

The EVA adhesive film has advantages in adhesion, durability, optical properties, etc., and is suitable for surface encapsulation of the thin-film solar cell layer 2 .

Further, the thin-film solar cell layer 2 is connected to the junction box 4 through the through hole on the tube wall 3 .

Further, the junction box 4 is a waterproof junction box.
