Abstract
A solar module patterning apparatus comprises a laser oscillator, a homogenizer and a scanner. The laser oscillator generates a laser beam having a predetermined wavelength. The homogenizer homogenizes an intensity distribution of the generated laser beam provided from the laser oscillator. The scanner scans the laser beam to a solar module. The laser beam is output from the homogenizer and passed through a mask with a predetermined pattern.
