ASM Alternative Energy Contributes to Significant Fine Line, High Aspect Ratio Conductor Printing Result on PERC Solar Cells

Working alongside long-time partner, Institute for Solar Energy Research Hamelin (ISFH), ASM Alternative Energy (AE) has recently contributed to some of the industry’s most impressive solar cell printing results. Utilizing an ASM AE Eclipse metallization platform, VectorGuard^TM Fine-Line Stencils, and precision metal squeegees in combination with ISFH’s proven PERC solar cell production techniques, fired conductor fingers measuring 28 µm wide by 20 µm high were successfully printed.

“A fired aspect ratio higher than 0.7 is a remarkable achievement,” explains Tom Falcon, ASM AE Principal Engineer. “This project yielded conductor fingers with aspect ratios of 0.71; a result that enables greater solar cell electrical efficiency and lower overall production cost. Indeed, this is a very positive development for the PV industry.”
