Embodiment Construction
[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0017] A kind of bimetallic solar cell based on thermoelectric effect, the specific manufacturing steps are as follows:
[0018] 1. Cut the bare wire specifications: diameter: 0.4 mm, cross-sectional area: 0.1256 mm2 constantan wire and copper wire with a length of 12 cm, and cut them into 100 wires;
[0019] 2. Cover the cut constantan and copper wires with ceramic tubes with an inner diameter of 1mm and a length of 90mm and a temperature resistance of 600°C;
[0020] 3. If figure 1 As shown, weld one end of the ceramic tube copper and constantan wire with oxygen welding to form a copper and constantan bimetal series connection unit;
[0021] 4. Then connect the copper and constantan bimetal series units with ceramic tubes in series, as shown in figure 2 shown;
[0022] 5. Bind together all the ceramic tubes connected in series with copper and constanta...

Abstract
The invention discloses a method for manufacturing a bimetallic solar cell based on thermoelectric effect. The steps include: cutting constantan wires and copper wires into a plurality of short wires; putting ceramic tubes on the outer surfaces of the constantan and copper wires; welding with oxygen Weld one end of the ceramic tube copper and constantan wire together to form a copper and constantan bimetal series connection unit; connect each unit in series; tie all the ceramic tubes together with adhesive tape to form a pair of metal bundles, after One end of the oxygen welding is collected at one end of the bimetallic beam, and the head and tail output without oxygen welding is placed at the other end of the bimetallic beam; place the magnifying glass in the sunlight, and place the oxygen-welded end of the bimetallic beam on the magnifying glass At the focal point of the metal, a temperature difference is generated at both ends of the metal, and the two outputs of the bimetallic beam obtain electric energy. The beneficial effect of the invention is that during the solar energy conversion process, the single crystal silicon in short supply is replaced by the bimetallic material, the production process is simple, the cost is reduced, and the solar cell can be popularized in a large area.
Description
technical field [0001] The invention relates to the manufacture of solar cells, in particular to a method for manufacturing bimetallic solar cells based on the thermoelectric effect. Background technique [0002] The entire industrial chain of photovoltaic cells in China presents a "pyramid" pattern of "down from the big to the top", and the expansion speed of silicon chip manufacturers lags behind that of cell manufacturers; on the other hand, in order to ensure the international competitiveness of domestic solar cells, export solar cells Countries such as Japan, Germany, and Sweden, which have the core raw materials required for panels, have reduced their supply to China, and most domestic photovoltaic downstream enterprises are in a situation of "cooking without rice". Moreover, the disadvantages of the traditional LED solar cell system (monocrystalline silicon) are: complex process; high cost, difficult to promote on a large scale; the United States, Germany, and Japan m...
