NOVELTY - The mixed-type heterojunction thin-film solar cell structure comprises a conductive substrate (10), a conjugate polymer layer (14) formed on the substrate, an inorganic wire array (16) inserted into the polymer layer, and an electrode layer (24) covering the wire array and the polymer layer. A non-conductive layer is formed between the polymer layer and the electrode layer to protect the wire array, has such a thickness that the wire array emerging from the polymer layer is higher than the non-conductive layer, and is made of a transparent material/an opaque material.    USE - Used as a mixed-type heterojunction thin-film solar cell structure.    ADVANTAGE - The mixed-type heterojunction thin-film solar cell structure can be economically manufactured with high flexibility, enhanced energy conversion efficiency and increased contact area.    DETAILED DESCRIPTION - The mixed-type heterojunction thin-film solar cell structure comprises a conductive substrate (10), a conjugate polymer layer (14) formed on the substrate, an inorganic wire array (16) inserted into the polymer layer, and an electrode layer (24) covering the wire array and the polymer layer. A non-conductive layer is formed between the polymer layer and the electrode layer to protect the wire array, has such a thickness that the wire array emerging from the polymer layer is higher than the non-conductive layer, and is made of a transparent material/an opaque material. A hole blocking layer (22) is formed between the conjugate polymer layer and the electrode layer and between the non-conductive layer and the electrode layer to cover the non-conductive layer and the inorganic wire array. The inorganic wire array has a nanometric structure, a micron structure, or a submicron structure. A spacing between two wires of the inorganic wire array is below two times diffusion length of excitons in polymer, is less than 100 mu m when the inorganic wire array has the micron structure or the submicron structure, and is less than 50 times width of a wire when the inorganic wire array has the nanometric structure. A length of wires of the inorganic wire array is adjusted according to an absorption coefficient of an inorganic material of the inorganic wire array. A hole transport layer (12) or an electron blocking layer is formed between the conductive substrate and the conjugate polymer. The hole transport layer or the electron blocking layer does not contact the inorganic wire array. Nanowire structures are formed on the micron structure or the submicron structure to increase contact area between the conjugate polymer layer and the inorganic wire array, when the inorganic wire array has a micron structure or a submicron structure. The conductive substrate is made of a transparent conductive substrate, a transparent-electrode glass substrate, a transparent-electrode plastic substrate, a transparent-electrode quartz substrate, and a thin metallic plate. The inorganic wire array has a total width of 300 nm to 100 m on the substrate. The conjugate polymer layer has a thickness of 30 nm to 5 mu m. Each wire of the inorganic wire array has a length of 50 nm to 50 mu m. Each wire has a width of 5-300 nm when the inorganic wire array is the nanometric structure, which is vertical to the substrate. Each wire has a width of 300-3000 mu m when the inorganic wire array is the micron structure, which is vertical to the substrate. A depth of the inorganic wire array is 30 nm to 5 mu m by inserting the wires of the inorganic wire array into the conjugate polymer layer when the inorganic wire array is a nanometric structure.
