Description

Technical Field

[0001] The utility model relates to the technical field of annealing devices, in particular to a photovoltaic cell annealing device which is convenient for taking and placing materials. Background Art

[0002] Photovoltaic annealing is a commonly used process in the production of solar cells. This process uses high temperature to anneal the solar cell panel to keep it in a thermal equilibrium state, thereby improving the electron mobility and effectively improving the conversion efficiency of the cell. The effective conversion efficiency of solar cells is limited by many factors, one of which is the energy band structure of amorphous silicon film. Photovoltaic annealing can improve the crystallinity of amorphous silicon film, thereby reducing the energy band structure defect density of amorphous silicon film and improving its conductivity and photocurrent efficiency.

[0003] A Chinese patent with publication number CN214043600U discloses a crystalline silicon photovoltaic solar cell electric injection annealing test device. When the motor rotates forward, it drives the second rotating shaft and the clamping plate to rotate, so that the solar panel rotates and is heated evenly. The motor is reversed to drive the impeller and the stirring rod to rotate, so that the coolant is transmitted to the top of the second partition to cool the heat-absorbing copper plate, so as to solve the problem that the coolant directly cools the solar panel and causes the solar panel to deform. The utility model solves the cooling problem of the original annealing device, reduces the annealing time, saves the annealing cost, improves the annealing efficiency, and brings convenience to merchants.

[0004] However, the above solution is not convenient for taking out the solar cells, and the solar cells need to be manually placed in the collection device, resulting in a slow material taking and placing process, which reduces the processing efficiency. In addition, the manual force is not easy to control, which can easily damage the solar cells.
