Laser transferred contacts: Modeling of the transfer process

This work presents a numerical model for the physical processes during the transfer process of our nickel/copper laser fine line metallization. Here, a pulsed laser transfers a thin nickel layer from a glass support and contacts the solar cell directly through the anti-reflection coating. The model simulates the temperature distribution in the nickel as well as the glass support and calculates the arising gas pressures at the nickel/glass interface. The gasification of the soda-lime glass support is the main driving force of the transfer process.
