The invention discloses a silicon cell labeling method which comprises the following steps: designing N2 different graphite boat clamping points easy to label; machining N1 mounting holes around a cell compartment corresponding to each silicon cell, wherein one graphite boat clamping point easy to label is mounted in each mounting hole; coating a graphite boat; for the identified Arabic numerals represented by the clamping point types corresponding to the N1 mounting holes which are around the cell compartment of the current silicon cell and are arranged in sequence according to the circumferential position distribution of the mounting holes, rearranging the Arabic numerals according to the digital sequence from one end to the other end of the mathematical counting unit to get an N1-digitserial number of the current silicon cell represented with a base-N2 system; and taking the serial number as the labeling number of the current silicon cell. The silicon cell labeling method is helpful for the troubleshooting and optimized analysis of silicon cells.
