Existing and emerging laser applications within PV Manufacturing


By Finlay Colville, Director of Marketing, Solar, Cohenernt, Inc.; Corey Dunsky, Manager of Commercial Applications Center, Cohenernt, Inc.; Jim Hopkins, General Manager of the Integrated Optics System Business Unit, Cohenernt, Inc.

Increasing the efficiency and yield of production line processes forms an integral part of PV manufacturers’ technology roadmaps. For their next generation production lines, non-contact processing equipment is considered essential. This prioritizes laser-based processing, already established at several steps in c-Si and Thin-Film cell manufacturing. This paper summarizes the key issues when using lasers within PV production lines.

The first edition of the Photovoltaics International journal, published in August 2008, was created in response to what was deemed to be a growing need for an unbiased technical publication for the solar cell and module manufacturing industry. With this in mind, the first edition of Photovoltaics International saw the commissioning of papers from a wide range of sectors, such as NREL’s overview of the CPV sector, IMEC’s thin-film efficiency gains via plasma texturing, site selection with IBM PLI, Q-Cells on silicon nitride thin films and Navigant Consulting’s market overview.
