A road surface power generation assembly is provided, which includes a substrate (1), a solar cell chip (2) and a glass layer (4, 5). The glass layer includes an upper glass layer (4) and a lower glass layer (5) which are secured through a sheet adhesive layer (3). The solar cell chip (2) is arranged between the lower glass layer (5) and the substrate (1). In the road surface power generation assembly, the glass layer is arranged to effectively protect the solar cell chip, thereby improving the tolerance of a road surface on which the road surface power generation assembly is arranged. The provided double layer glass can be bonded through hot pressing, to effectively prevent from breaking and falling off, thereby improving the security. In addition, the double layer glass are connected through the sheet adhesive layer, which achieves a soft connection, thereby improving toughness of the glass, and improving a cushioning effect.
