AIP Conference Proceedings [AIP Publishing INTERNATIONAL SYMPOSIUM ON GREEN AND SUSTAINABLE TECHNOLOGY (ISGST2019) - Perak, Malaysia (23–26 April 2019)] INTERNATIONAL SYMPOSIUM ON GREEN AND SUSTAINABLE TECHNOLOGY (ISGST2019) - Metallization contributions, requirements, and effects related to pattern transfer printing (PTP?) on crystalline silicon solar cells

摘要： In this work, the metallization requirements and development for an alternative fine line printing method to screen printing, called pattern transfer printing (PTP?), are discussed. This technique has been proven in high volume environments and shows impressive capability of printing lines down to 20μm consistently and reliably. With such a major reduction (nearly 50%) in contact area and paste volume, there are some critical aspects of the metallization paste that must be addressed. After these modifications have been made, an efficiency gain of 0.14%abs is demonstrated for the PTP? process versus that of a state-of-the-art screen-printed paste on an industrial scale under otherwise identical conditions.
