A power generation device for a surface of a wall, which is used for solving the problem that existing power generation devices cannot use the natural energy contained around a wall of a building. The power generation device comprises a friction power generator. The friction power generator further comprises: a first electrode layer arranged on a surface of a wall, and a second electrode layer arranged on a surface of the first electrode layer, wherein the first electrode layer is a plate-shaped electrode layer, and comprises a first electrode (11) arranged on the surface of the wall; and the second electrode layer is an electrode layer with a plurality of bulge structures, and one closed cavity is formed between each bulge structure and the first electrode layer, wherein the second electrode layer comprises a second high-molecular polymer insulation layer (12) and a second electrode (13) which are overlapped, and the second high-molecular polymer insulation layer (12) is located between the first electrode layer and the second electrode (13), the first electrode (11) and the second electrode (13) being electric energy output ends of the friction power generator. |
