Embodiment Construction
[0025] A solar photovoltaic / photothermal coupling power generation method, which creatively integrates solar photovoltaic power generation and photothermal power generation. On the light-facing surface, the photovoltaic module adopts a PN junction structure; at the same time, a diplex pulsating heat pipe is integrated on the backlight surface to realize direct heat generation. generate electricity.
[0026] Figure 6 Schematic diagram of the principle of photothermal power generation. The working principle of the photovoltaic / photothermal coupled solar cell is: the diplex pulsating heat pipe is alternately filled with a high-boiling-point conductive working medium A and a low-boiling point insulating working medium B, wherein the low-boiling point insulating working medium B absorbs light from the The solar heat on the surface undergoes a phase change and absorbs heat, and the low-boiling point insulating working medium B is heated to become a gas-phase insulating working med...

The invention belongs to the technical field of solar power generation and discloses a solar photovoltaic and optothermal coupling type solar battery and a coupling power generation method thereof. The battery is composed of a phototropic face photovoltaic power generation module, a silicon channel, a silica-based back plate processed with permanent magnetic film arrays and cooling fins. On one side of a system facing the sun, electric potentials are generated in the photovoltaic power generation module for photovoltaic effects when sunlight illuminates; on a shady face, a vacuum pumping liquid injection port on the silica-based back plate faces an S-shaped micro-channel on a micro-channel plate, the micro-channel is filled with high-boiling-point conductive working media A and low-boiling-point insulation working media B alternatively, and then the micro-channel is sealed, so that a snake loop forms a pulsating heat pipe loop with two working media. The solar photovoltaic and optothermal coupling type solar battery has the advantages that a shady face pulsating heat pipe power generation loop absorbs heat released by the phototropic face for power generation, so that the work temperature of a photovoltaic panel is low, the conversion efficiency of the photovoltaic panel is improved, and the service life is increased, and a wide application prospect is provided.
Description
technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar photovoltaic and light-heat coupled solar cell and a coupled power generation method thereof. Background technique [0002] Energy shortage and environmental pollution have become one of the main bottlenecks restricting the development of human civilization. Solar energy is an inexhaustible clean energy, and its efficient utilization has become one of the main ways to alleviate the energy crisis. Solar power generation technology can be divided into two categories, that is, photovoltaic power generation technology that converts sunlight energy into electrical energy, and photothermal power generation technology that converts solar radiation heat energy into electrical energy. Photovoltaic power generation mainly utilizes the photovoltaic effect of semiconductor materials (PN junctions). Photothermal power generation usually uses thermal power conversion te...
