Abstract

A processing system for producing solar cells is provided. The processing system includes a conveyor belt system. The conveyor belt system includes a conveyor belt for transporting a solar cell wafer. Furthermore, the processing system includes a laser unit configured to direct a laser beam onto the solar cell wafer during transportation of the solar cell wafer by the conveyor belt. Furthermore, a conveyor belt system for use in the production of solar cells is provided that includes a support surface with several openings in the support surface; a conveyor belt with several openings in the conveyor belt; and a first underpressure circuit connected to at least a part of the multitude of openings in the support surface. Furthermore, a method for producing solar cells is provided. The conveyor belt system includes transporting a solar cell wafer; and, during transporting, directing a laser beam to the solar cell wafer.

Description

technical field [0001] Embodiments of the present disclosure relate to a solar cell processing system for producing solar cells, a conveyor belt system for use in the solar cell processing system, a solar cell production apparatus, and a method of producing solar cells. Specifically, embodiments of the present disclosure relate to a solar cell processing system for producing passivated emitter rear contact (PERC) solar cells, a conveyor belt system for use in a PERC solar cell processing system, configured to use A solar cell production device for producing PERC solar cells and a method for producing PERC solar cells. Background technique [0002] A solar cell is a photovoltaic (PV, photovoltaic,) device that converts sunlight into electrical energy. A typical solar cell includes a substrate, which may also be referred to herein as a wafer. Wafers are typically made of silicon. The wafer may have one or more p-n junctions or p-i-n junctions formed therein. Each p-n junct...
