However, its installation cost is high, mainly due to the requirement of high wind resistance, flat photovoltaic cells are heavy, difficult to install, and selective orientation, etc., and usually the operating temperature of photovoltaic cells is as high as 40-60 degrees Celsius, which reduces the energy conversion efficiency
On the other hand, the photothermal photoelectric system has gradually received attention, which can effectively use solar energy in multiple channels, but both photothermal tubes and photovoltaic cells need to occupy a large roof area

The invention discloses an integrated photoelectric / photo-thermal device which comprises a tubular heat absorption / heat conduction liner, wherein a light absorption layer is arranged on the outer wall of the tubular heat absorption / heat conduction liner in a covering manner, is composed of a photocell and is packaged in a vacuum transparent packaging tube; an inner light reflecting layer is arranged on the inner wall of the vacuum transparent packaging tube in a covering manner. The integrated photoelectric / photo-thermal device has the following advantages: the thermal energy generated by the photocell can be conducted out, so that the photocell working temperature is reduced, the energy conversion efficiency is improved, the thermal energy can be utilized, and the solar energy utilization efficiency is improved on the whole; a columnar appearance is adopted to absorb solar energy by 360 degrees, and the problem about orientation of the integrated photoelectric / photo-thermal device to the sun does not need to be taken into consideration when the integrated photoelectric / photo-thermal device is mounted and designed, so that the integrated photoelectric / photo-thermal device can be paved on a roof to increase electric energy output of roof unit area; in addition, as gaps are reserved among components when the integrated photoelectric / photo-thermal device is mounted, and the wind resistance is small, the fixing cost is remarkably reduced; moreover, as the vacuum glass packaging tube is adopted for protection, the service life of the photocell is greatly prolonged.
Description
technical field [0001] The invention belongs to the field of optoelectronic devices, relates to a solar photoelectric device, in particular to a photoelectric / photothermal integrated device. Background technique [0002] As the energy crisis becomes more and more serious, people pay more and more attention to renewable energy. Among them, solar energy has become the most potential technology because of its inexhaustibility, cleanliness and pollution-free. In recent years, photovoltaic integrated buildings have begun to rise, which have the advantages of green energy, no land occupation, grid-connected photovoltaic systems, no need for batteries, and building energy conservation. However, its installation cost is high, mainly due to the requirement of high wind resistance, the heavy weight of flat photovoltaic cells, difficult installation and selective orientation, etc., and the operating temperature of photovoltaic cells is usually as high as 40-60 degrees Celsius, which r...
