NOVELTY - The thin-film solar cell comprises a transparent substrate (1), on which successive layers including a transparent front electrode layer (3), a semiconductor layer (4) and a rear electrode layer (5) are deposited. A transparent structured layer (2) is applied to the substrate before depositing the layers, is made of a matrix obtained according to a sol-gel-process and particles providing structure, and forms a texture-template for the deposited layers including the rear electrode layer. The structured layer has a refractive index, which is greater than the refractive index of the substrate.    USE - Used as a thin-film solar cell.    ADVANTAGE - The thin-film solar cell can be economically manufactured with high efficiency, improved conductivity and reflectivity and less material consumption.    DETAILED DESCRIPTION - The thin-film solar cell comprises a transparent substrate (1), on which successive layers including a transparent front electrode layer (3), a semiconductor layer (4) and a rear electrode layer (5) are deposited. A transparent structured layer (2) is applied to the substrate before depositing the layers, is made of a matrix obtained according to a sol-gel-process and particles providing structure, and forms a texture-template for the deposited layers including the rear electrode layer. The structured layer has a refractive index, which is greater than the refractive index of the substrate and highly greater like the refractive index of the front electrode layer deposited on the structured layer. The rear electrode layer has a transparent rear electrode partial layer on its side turned to the semiconductor layer. The transparent substrate is glass or glass ceramic. The front electrode layer consists of zinc oxide or tin oxide. The refractive index of the structured layer is 1.6-1.8. A diffusion barrier is deposited under or above the structured layer. The thin-film solar cell has more than a pn-junction. The average layer thickness of the structured layer is 0.1-1 mu m. The aspect ratio of the structured layer is 0.01-0.99. The volume ratio of the matrix to the particles of the structured layer is 70:30-5:95. The particles providing structure have a particle size of 0.02-1 mu m, are symmetrically formed by agglomerates, are coated with an acid-resistant protective layer, and are formed by photoluminescent particle. The matrix is formed from particle having a particle size of less than 20 nm. The semiconductor layer consists of a semiconductor based on silicon or a compound semiconductor. An INDEPENDENT CLAIM is included for a method for manufacturing a thin-film solar cell.    DESCRIPTION OF DRAWING(S) - The diagram shows a cross-sectional view of a thin-film solar cell.
