NOVELTY - The converter has a light through straight pipe device provided with a solar photoelectrical conversion coating for converting solar energy into electric energy, where the light through straight pipe device is provided with an inlet and an outlet. An inner side and an outer side of the light through straight pipe device is provided with a heat exchanger and/or heat exchange fluid, where the cavity is in the shape of cylinder, sphere, ellipse and polygon. An insulating material is arranged in the parts in which solar light cannot irradiate the pipe device or the heat exchanger.    USE - Solar straight pipe photoelectrical converter.    ADVANTAGE - The opening end of the through pipe can be closed for operation without the need of additional packaging, thus reducing the cost of the current solar photoelectrical conversion material. A fluid or heat pipe can be arranged in the cavity of a pipe device to control temperature of the solar photoelectrical conversion material for high conversion efficiency. The heat energy can be comprehensively utilized to transmit by the fluid or heat pipe such that the converter performs solar power generation and temperature control, and improves solar conversion efficiency and comprehensive solar utilization.    DETAILED DESCRIPTION - The conversion coating is selected from one of mono-crystalline silicon coating, multi-crystalline silicon coating, non-crystalline silicon coating, and crystalline silicon film coating. The heat exchanger and the pipe device are connected by transition material connection such as kovar alloy, metal or ceramic transition material or internal or external corrugated pipe connection or non-metal soft connection, including rubber ring, sealing pad, silica gel ring and stopper. The heat exchanger is selected from one of metal, non-metal, metal and non-metal composite pipe, and evaporation end of a heat pipe. The insulating material is selected from one of metal or non-metal material including vacuum layer, asbestos or fiber insulating material, insulating cement, polyphenyl, plastic material or nylon and insulating coating.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a solar straight pipe photoelectrical converter.
