Summary: This study investigates the printing behaviors of a single microdroplet in laser-induced forward transfer (LIFT) through experiments and simulations. Three printing behaviors are observed, including non-release deposition, single microdroplet deposition, and splash deposition. Weber number and nominal capillary number are proposed as the criteria for the low and high thresholds of single microdroplet deposition.

Summary: Laser-induced forward transfer (LIFT) is an innovative metallization technique used in the processing of solar cells. This study investigated the morphology and transfer mechanisms of formed lines with high-viscosity silver paste and small gap. Different transfer states and thresholds were observed under different laser fluences. The line width increased with higher laser fluence. The characteristics of the transferred silver paste varied depending on the laser fluence. This work provides insights for improving fine-line metallization and understanding transfer mechanisms in photovoltaic applications.
