NOVELTY - The converter has a linear opening part placed on a flat plate black body apparatus i.e. column body apparatus. A solar coating layer is placed on the black body apparatus to convert solar energy into heat energy. The solar coating layer introduces sunlight to an inner coating layer of a cavity body via an opening part of the black body apparatus to convert the solar energy into the heat energy. Multiple linear black apparatuses are arranged row by row and commonly placed on a flat plate. A fin and slot channel comprises multiple concave/convex structures placed on the black body apparatus.    USE - Solar photoelectric converter e.g. slot-type solar energy solar photoelectric converter, tower-type solar energy solar photoelectric converter and butterfly-type solar energy solar photoelectric converter.    ADVANTAGE - The concave/convex structures placed on the black body apparatus increase the photoelectric converting performance of the converter. The solar coating layer introduces the sunlight to a back part of the cavity body via an opened part to maximally absorb the sunlight, thus increasing energy conversion efficiency of the converter. The black body apparatus is made of quartz material, plastic, metal and glass, so that the converter is manufactured at low cost. The converter comprises solar mirrors reflecting, refracting and projecting the sunlight to the black body apparatus, thus improving sunlight collection efficiency of the converter at high temperature.    DETAILED DESCRIPTION - The black body apparatus is coated with a thermal insulated material selected from a group consisting of asbestos and fiber thermal insulated material, thermal insulated cement, polyurethane, polyphenyl, plastic and a d-nylon thermal insulated material. The solar coating layer is selected from a group consisting of a solar opto-electrical coating layer, a mono-crystal silicon coating layer, a polysilicon coating layer, a non-crystal silicon membrane coating layer and a crystal silicon membrane coating layer.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a solar photoelectric converter.
