This paper reports on the investigation of cavitated silver paste produced by cavitation technology as a cost-effective alternative to traditional three-roll milling (TRM). Cavitation, utilizing high-frequency sound waves, enhances metal paste dispersion, reduces oxidation, extends shelf life, and minimizes waste. Passivated Emitter and Rear Cell (PERC) solar cells made with cavitated silver paste achieved a 21% energy conversion efficiency, slightly lower than the 22% efficiency of conventional paste. Cavitated paste produced finer gridlines, reducing silver usage and costs but increasing contact resistance, leading to a lower fill factor. Despite this, cavitation technology shows promise for more efficient and cost-effective solar cell production. Further research is needed to optimize efficiency and resistance, highlighting the potential for cavitation technology in commercial applications.
