  • Dec 2020
Laser micromachining provide significant effect in thin film solar industrial field especially in determining cell efficiency of each panels. However, there is an issue in determining scribing failure or defect on solar module. This research aims to investigate the defects of laser micromachining process in thin film solar module in manufacturing f...

Context 1
... most common thin film technology used today is cadmium telluride (CdTe) film cells type [3]. Figure 1 show the deposition layer of thin film solar cell based on CdTe semiconductor properties and how it convert sun rays into electrical power. The light from sunrays entering through the Transparent Conductive Oxide (TCO) glass substrate. ...
