The invention relates to the technical field of solar cells, and discloses a high-conversion-efficiency doped single-crystal double-sided solar cell and a preparation method thereof. The high-conversion-efficiency doped single-crystal double-sided solar cell comprises a placement frame, a cell panel and a reflector. The top end of the placement frame is fixedly connected with a first support, and the tail end of the first support is rotatably connected with the cell panel through a pin shaft. Compared with a common single-sided battery, the double-sided battery has obvious advantages, both sides can generate electricity, and the overall generating capacity is increased by reducing the area of a back aluminum laminated film, so that the output power of the double-sided battery is much higher than that of a traditional single-sided battery. Sunlight is reflected through the reflector arranged below the cell panel, the light receiving area of the back side of the cell panel is larger through diffuse reflection generated by the uneven reflector, and the power generation efficiency is higher. The angle of the reflector can be adjusted according to the angle of sunlight, and the back side of the cell panel can receive light and generate electricity for a long time.
Description
technical field [0001] The invention relates to the technical field of solar cells, in particular to a high-conversion-efficiency doped single-crystal double-sided solar cell and a preparation method. Background technique [0002] Solar cells, also known as photovoltaic power generation, are the most promising fields in new energy technologies. Distributed photovoltaic power generation has developed rapidly in my country in recent years, and distributed photovoltaic power generation is an important development direction in the future. Since distributed photovoltaic systems need to be able to generate more electricity per unit area, monocrystalline cells with higher efficiency per unit area will be more attractive. The deep integration of information technology and manufacturing industry has given birth to a new production mode of intelligent manufacturing. Intelligent manufacturing has become an important research direction of the photovoltaic industry in recent years, promo...
