High purity alumina ceramic vacuum sucker for solar cells

 High purity alumina (HPA) is a crucial material used in various solar applications. One of its important uses is in the manufacturing of solar cells, where it is employed as a sucker or holder during the production process.   Solar cells are made up of multiple layers, including a substrate, semiconductor material, and metallic contacts. HPA is used as a sucker to hold these layers together during the deposition and annealing processes. It ensures that the layers remain aligned and prevents any unwanted movement or distortion.     The high purity of alumina is essential in this application because impurities can negatively affect the performance and efficiency of solar cells. HPA provides excellent thermal stability, electrical insulation, and resistance to corrosion, making it an ideal material for this purpose.Furthermore, HPA can withstand high temperatures, which is crucial during the manufacturing process of solar cells. It also has a low coeffici…
