Tracing method and transport device for solar cells

A transport device for solar cells, comprising a computer system, wherein the computer system includes:

• at least one processor;
• and
• a memory communicatively coupled to the at least one processor;
• wherein the memory is configured to store instructions, which, when executed by the at least one processor, cause the at least one processor to implement operations of a method for tracing solar cells, wherein the method includes:
• coding solar cells disposed in a loading frame according to a frame code of a loading frame, such that the respective solar cell has a respective cell code;
• obtaining respective process information of the respective solar cell according to a loading order in which the solar cells are transferred from the loading frame to a transport and grouping apparatus, wherein the respective process information includes a code of a process carrier configured to carry the solar cells, a code of a workbench configured to process the solar cells and a position code of the respective solar cell in the process carrier;
• receiving cell codes and process information of the solar cells sent to the software system;
• and
• recording, by the software system, the cell codes and the process information of the solar cells, and associating, by the software system, the respective cell code with the respective process information.
