NOVELTY - Manufacturing a dye-sensitized solar cell comprises arranging a photo-active layer (22) comprising a matrix of a non-conductive material and discrete components (12); and adding an electrolyte (32) in a gap (33) between the photo-active layer and a front electrode (34). The discrete components comprise a porous structure (18) of a semiconductive material over part of its outer surface between the transparent front electrode (34) and a back electrode (28). The discrete components are in electrical contact with the back electrode and with the electrolyte.    USE - Method of manufacturing a dye-sensitized solar cell for conversion of light into electricity (claimed).    ADVANTAGE - The method has quicker processing steps, allowing dye-sensitized solar cells to be produced continuously. Continuous production offers lower manufacturing costs. The photo-active layer comprising discrete components having a porous structure at least over part of its outer surface in a non-conductive matrix is a semi-finished article. This semi-finished article is prepared separately. The lengthy adsorption step required for filling the pores of the outer porous structure of the discrete components does not affect the process time of the method. The matrix acts as a common support or carrier for the components, allowing easy handling and positioning with respect to the other components.    DETAILED DESCRIPTION - Manufacturing a dye-sensitized solar cell comprises arranging a photo-active layer (22) comprising a matrix of a non-conductive material and discrete components (12); and adding an electrolyte (32) in a gap (33) between the photo-active layer and a front electrode (34). The discrete components comprise a porous structure (18) of a semiconductive material over part of its outer surface between the transparent front electrode (34) and a back electrode (28), leaving free a gap between the photo-active layer and the transparent front electrode. The porous structure has a light-sensitive dye. The discrete components are partially exposed on both main surfaces (26, 30) of the photo-active layer. The discrete components of the photo-active layer are in electrical contact with the back electrode and with the electrolyte.
