NOVELTY - The converter has a blackbody with sealed cavity, and a solar photo-thermal converting coat and a photoelectric converting coat arranged in the blackbody for converting solar energy into heat and electric energy. Sunshine is irradiated on the coats in the cavity via an opening of the blackbody for converting the solar energy. The blackbody is in shape of cylinder, sphere, cone or polyhedron or section selected from one of group consisting paraboloid, composite paraboloid, hyperbolic paraboloid, ellipse, triangle, tower and prism. A heat preservation material is placed outside the blackbody.    USE - Blackbody solar photo-thermal photoelectric converter.    ADVANTAGE - The sunshine is irradiated into the blackbody through an opening, and loss caused by reflection, irradiation and transmission is reduced, and converting efficiency is improved. Different solar lenses are used to reflect, irradiate and project the sunshine into the blackbody, so as to achieve solar collection at different temperatures.    DETAILED DESCRIPTION - The blackbody is made of one material in a group consisting of stainless steel, iron pipe, quartz, glass, plastic and composite pipe of metal and non-metal, metal and metal, and non-metal and non-metal. The solar coat is selected from one of the group consisting of solar selecting coat, solar low temperature, middle temperature and high temperature coats for converting solar energy into heat of different temperature, a coat in the blackbody for converting solar energy into electricity and a solar cell sheet for converting the solar energy into electricity. The coat in the outer shell of the blackbody is selected from one of the group consisting of thermal radiation absorbing coat for absorbing and using radiation, thermal radiation reflecting material for reflecting the radiation into the blackbody, wetting paint, corrosion resistant coat and heat resistant coat. The heat preservation material is selected from one of group consisting of metal or non-metal material with vacuum layer, asbestos and fiber heat preservation material, heat preservation cement, poly-benzene material, plastic and nylon.    DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a blackbody solar photo-thermal photoelectric converter.
