Detailed ways

Below in conjunction with the accompanying drawings, the specific implementation of the utility model will be further described in detail, so as to make the technical solution of the utility model easier to understand and grasp.

Referring to Figures 1-2, a photovoltaic module suitable for building exterior walls includes a photovoltaic module body 1, the photovoltaic module body includes a tempered glass layer 11, and a concentrating glass layer 12 is provided on the lower part of the tempered glass layer , the upper part of the concentrating glass layer is provided with more than one converging point 121, the lower part of the concentrating glass layer is provided with a transparent rubber layer 14, and the upper surface of the transparent rubber layer is coated with fluorescent powder (not shown in the figure) , the fluorescent powder is coated in the gap between the battery sheets, and the fluorescent powder is not coated in the groove. The photovoltaic module body 1 is used to generate electricity during the day and is used as an ornament at night to replace today’s neon lights. Energy is saved, the transparent rubber layer is provided with a groove, and the battery sheet 13 is fixedly connected in the groove, and the light-concentrating point 121 is set corresponding to the battery sheet 13, and the light-concentrating point can gather light on the battery sheet.
