The solar components in the existing solar street lamps generally choose monocrystalline silicon or polycrystalline silicon solar components, and the components are generally set up at a certain inclination angle through brackets. In order to maximize the use of sunlight, it is necessary to find an optimal inclination angle , In addition, the component bracket also needs to be designed for wind resistance, and the street light pole usually needs to be fixed on the embedded parts, which is relatively complicated. For example, Patent Document 1 discloses a solar cell street lamp, wherein the solar cell is arranged on the side of the street lamp facing sunlight.

With the development of dye-sensitized solar cells, there are also street lamps using dye-sensitized solar cells. For example, Patent Document 2 discloses a street lamp with a curved solar panel, and a dye-sensitized thin-film solar panel is pasted on the upper surface of the lampshade.
