Laser scribing for buried contact solar cell processing
전극함몰형 태양전지의 제조를 위한 레이저 scribing
Abstract
Laser scribing of silicon plays an important role in metallization including the grid pattern and the front surface geometry which means aspect ratio of metal contacts. To make a front metal electrode of buried contact solar cell, we used ND:YAG lasers that deliver average 3-4W at TEM
