Embodiment 1
[0066] Embodiment 1: blind tube solar photoelectric photothermal converter
[0067] according to figure 1 As shown, the shape of the dead-leg device is a cylinder (1), and a solar photoelectric and photothermal coating (3) is processed on the cavity inside the cylinder. The blind-leg is made of white glass material with good light transmission, and the solar light The coating on the inside shines through the white glass to convert solar energy into electricity.
[0068] The device can be used directly, or a fluid can be provided through the open end (5), and the fluid transfers the heat energy inside the dead leg to the outside, so as to realize the temperature control of the device and the collection of heat energy.
Embodiment 2
[0069] Embodiment 2: heat pipe solar photoelectric photothermal converter
[0070] according to figure 2 As shown, the shape of the blind-leg device is a cylinder (1), and the solar photoelectric photothermal coating (3) is processed on the cavity inside the cylinder to be monocrystalline silicon and solar selective coating, and the blind-leg is light-transmitting With good plastic, solar light shines through the plastic to the coating on the inside, which converts solar energy into electricity.
[0071] The evaporation end of the heat pipe is arranged inside the cavity of the dead pipe device, the heat pipe is connected to the dead pipe device through the connection structure (4), and the condensation end is arranged outside the dead pipe; for low temperature applications, non-tracking solar energy collection can be used, For medium-temperature applications, trough-type line-focused solar energy collection can be used, and for high-temperature applications, butterfly-type o...
Embodiment 3
[0072] Example 3: Hexagonal blind tube photoelectric photothermal converter
[0073] according to image 3 As shown, a hexagonal external cavity (7) is also provided on the outside of the cylindrical dead-leg device (1), and a solar lens (8) is arranged on the sunlight incident part of the blind-leg device. The heat exchanger (2) is a stainless steel cylindrical device, the cavity of the dead-leg device is provided with a coating for converting solar energy into electrical energy, and the silicon layer on the glass substrate is characterized by a p+ layer: 10 μm to 40 μm thick , resistivity 2~3?0-8 ohm cm; p layer: 8 靘~10 Ω, resistivity: 0.2~2 ohm cm; n+ layer: 0.2 靘~0.4 Ω thick, resistivity 1~2?0-3 Ohm cm; the glass substrate is divided into 10mm*10mm regions. At the same time, solar light-to-heat conversion coatings of 10mm*10mm are arranged, and the ratio thereof is 50% of the total area.
[0074] The heat exchange device is arranged inside the blind pipe device, and an ...
