As a further improvement of the present invention, the bonding force of the easy-to-bond layer with the solar energy bonding glue is greater than 200N, which can make the bonding between the high transparency film and the solar cell sheet more firm, and make the overall stability of the solar cell module more stable. high.

As a further improvement of the present invention, the double-sided high-transparency film assembly is set on the glass curtain wall through transparent glue, so that the assembly is well pasted on the glass curtain wall and ensures excellent light transmission, so that the glued part Does not block the sun's rays.

As a further improvement of the present invention, the double-sided highly transparent film module is adsorbed on the glass curtain wall through an electrostatic layer, so that the module can be adsorbed on the glass curtain wall very smoothly, not only firmly adsorbed but also because there is no gap between the film and the glass curtain wall. The interlayer makes the light transmittance excellent and further improves the power generation efficiency.

As a further improvement of the present invention, the double-sided high-transparency film module is fixed on the glass curtain wall by bolts, so that the module can be placed on the glass curtain wall extremely firmly, and it is difficult to fall off from the glass curtain wall without being affected by the outside world .

As a further improvement of the present invention, the solar cells are directly covered on the glass curtain wall, which can further reduce the burden on the glass curtain wall, and at the same time reduce the amount of highly transparent film and reduce the cost.
