摘要:
Dichlorosilane and diborane are deposited on the titanium-based alloy film to grow a p+ type back surface field film. The temperature is raised to grow a p− type light-soaking film on the p+ type back surface field film. Phosphine is deposited on the p− type light-soaking film to form an n+ type emitter. Thus, an n+-p−-p+ laminate is provided on the titanium-based alloy film. SiCNO:Ar plasma is used to passivate the n+-p−-p+ laminate, thus forming an anti-reflection film of SiCN/SiO2 on the n+ type emitter. The n+-p−-p+ laminate is etched in a patterned mask process. A p− type ohmic contact is formed on the titanium-based alloy film. The anti-reflection film is etched in a patterned mask process. The n+ type emitter is coated with a titanium/palladium/silver alloy film that is annealed in hydrogen. An n− type ohmic contact is formed on the n+ type emitter.
摘要:
A method is disclosed for making an anti-reflection film of a solar cell. The method includes the step of providing a laminate. The laminate includes a ceramic substrate, a titanium-based compound film, a p+ type poly-silicon back surface field, a p− type poly-silicon light-soaking film and an n+ type poly-silicon emitter. The laminate is passivated with SiCNO:Ar plasma in a plasma-enhanced vapor deposition device, thus filling the dangling bonds of the silicon atoms at the surface of the n+ type poly-silicon emitter, the dangling bonds of the silicon grains at the grain boundaries of the p− type poly-silicon light-soaking film and the dangling bonds of the silicon atoms in the p+ type poly-silicon back surface field. Finally, the n+ type poly-silicon emitter is coated with an anti-reflection film of SiCN/SiO2.
