Technical Field
The invention relates to the field of efficient crystalline silicon solar cell manufacturing, in particular to 9-cavity vertical HWCVD-PVD integrated equipment for solar cell manufacturing.
Background
Currently, a class of advanced and efficient crystalline silicon solar cells is based on amorphous silicon/crystalline silicon heterojunction structures. The two very critical steps in the production technology are the deposition of an amorphous silicon-based film (comprising an intrinsic layer and a doped layer, and the material is amorphous silicon, microcrystalline silicon, nano-silicon, oxygen-doped amorphous silicon and the like) and the deposition of a transparent conductive oxide TCO layer. The deposition method of the amorphous silicon-based thin film which is commonly used is a low-temperature chemical vapor deposition method, including two methods, namely Plasma Enhanced Chemical Vapor Deposition (PECVD) and Hot Wire Chemical Vapor Deposition (HWCVD); the TCO layer is generally prepared by PVD (magnetron sputtering) method. In production, the corresponding devices of the two technologies are usually separated. Namely, the low-temperature CVD equipment is an independent system, and generally comprises a feeding and preheating cavity, an intrinsic layer deposition cavity, a doping deposition cavity (p-type or n-type), a blanking cavity and the like; the PVD equipment also comprises a feeding cavity, a preheating cavity, a film deposition cavity, a blanking cavity and the like. A feeding device and a discharging device of the silicon wafer, a conveying device for conveying the silicon wafer among different devices and the like are also needed between the CVD system and the PVD system. The overall system is very complex. Moreover, the product must be exposed to air during the transfer process between the CVD and PVD systems, so that the surface of the product is affected by water vapor, oxygen, dust and the like in the air to cause performance reduction; the operation cost is high in production, and the number of required workers is large.
