The present invention discloses a solar cell having a multi-layered structure that is used to generate, transport, and collect electric charges. The multi-layered nanostructure comprises a cathode, a conducting metal layer, a photo-active layer, a hole-transport layer, and an anode. The photo-active layer comprises a tree-like nanostructure array and a conjugate polymer filler. The tree-like nanostructure array is used as an electron acceptor while the conjugate polymer filler is as an electron donor. The tree-like nanostructure array comprises a trunk part and a branch part. The trunk part is formed in-situ on the surface of the conducting metal layer and is used to provide a long straight transport pathway to transport electrons. The large contact area between the branch part and the conjugate polymer filler provides electron-hole separation.

Method for forming a solar cell with tree-like nanostructure

A flexible photo-anode of dye-sensitized solar cell and a manufacturing method thereof are provided. The method includes steps of: coating zinc oxide nanoparticles on a flexible substrate to form a seed layer; immersing the flexible substrate into a first reaction solution; heating the seed layer to form a zinc oxide nanowire array; cooling the flexible substrate to the room temperature, immersing it into the second reaction solution, and stirring the second reaction solution, so that the zinc oxide nanowire array forms a cactus-like structure. Thus, the sintering and embossing processes can be prevented.
