Optionally, the see-through film 320 is colorless or colored in color.
The one-way perspective film can be set to be colorless or other various colors according to the needs of different buildings. For example, in serious places such as the police, a colorless one-way see-through film can be arranged; in the case of commercial buildings, colored solar curtain walls are required to enhance the aesthetic sense, and the one-way transparent film may be colored, such as blue. Moreover, after the glass is plated with the color one-way perspective film, when the external incident light enters, the light entering the room can be reduced, the reflected light is increased, and then the color effect of the light-transmitting solar module is more obvious, and the color effect is better compared with the traditional two-way perspective light-transmitting solar module.
