A fully-integrated solar factory - requirements for achieving grid parity


By Sylvère Leu, Conergy AG

Each year, the photovoltaic market grows at a two-digit growth rate. However, the resulting economy-of-scale effects are not enough to achieve grid parity on their own. In order to reduce the production costs to grid parity level, new concepts and ideas must be realised as the basis for a photovoltaic factory. There are four main requirements that must be fulfilled in order to adhere to this cost reduction strategy: a highly integrated factory; automated and stable processes; a production control system (PCS) that provides the statistic data in order to continually optimise the processes; and an optimally-sized aligned production capacity.

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.
