Division device and division method thereof

A division device, being to divide a solar cell sheet into two solar cell units, the solar cell sheet having a front surface prepared with a trench extending along a division direction, the two solar cell units being connected at the trench, the division device comprising:

• a platform, having a platform surface;
• a withstanding element, located on the platform surface, having at least one shrink-top-type withstanding structure protruding from the platform surface and extending along a withstanding line, the shrink-top-type withstanding structure being to withstand the solar cell sheet;
• and
• a pressure element, located above the platform, having two forcing portions protruding toward the platform;
• wherein, while the solar cell sheet is under dividing, a back surface of the solar cell sheet opposing to the front surface is arranged to face the shrink-top-type withstanding structure by aligning the trench with the withstanding line, and then the two forcing portions are introduced to apply predetermined depression individually onto the two solar cell units, such that the solar cell sheet are divided into the two separate solar cell units.
