Embodiment 1
[0065] Embodiment 1: Through-tube solar photoelectric and photothermal converter
[0066] according to figure 1 As shown, the through pipe device is a cylindrical pipe fitting (1), and a solar photoelectric and photothermal coating (3) is processed on the cavity inside the cylinder. The through pipe is made of white glass material with good light transmission, and the solar light is transparent. The clear glass shines onto the coating inside to convert solar energy into electricity.
[0067] The device can be used directly, or a fluid can be provided through the open end (5) and the inlet end, and the fluid transfers the heat energy inside the tube to the outside, so as to realize the temperature control of the device and the collection of heat energy.
Embodiment 2
[0068] Embodiment 2: heat pipe solar photovoltaic and photothermal converter
[0069] according to figure 2 As shown, the through pipe device is a cylindrical pipe (1), and the solar photoelectric and photothermal coating is processed on the inner cavity of the cylindrical pipe (3) is monocrystalline silicon and solar selective coating, and the through pipe has good light transmission Plastic, solar light shines through the plastic to the inner coating, which converts solar energy into electricity.
[0070] The evaporation end (2) of the heat pipe is set inside the cavity of the through-pipe device, the heat pipe is connected to the through-pipe device through the connection structure (4), and the condensation end is set outside the through-pipe; for low temperature applications, non-tracking can be used For solar energy collection, for medium temperature applications, trough-type line-focused solar energy collection can be used; for high-temperature applications, butterfly-...
