The light conversion region may be a light conversion region, and the type of the light conversion region may be selected according to actual needs, which is not limited herein.

Because the cell piece is very fragile, takes place destruction easily when the pressurized, photovoltaic glass and photovoltaic backplate can not directly be attached to it, therefore needs first glued membrane and second glued membrane to play the adhesive action in the middle.
