Temperature profiling for PV manufacturing

12 May 2010 Manufacturing / Production Technology, Hardware & Services

Datapaq recently introduced three new products in its SolarPaq series for photovoltaic (PV) cell and module manufacturers. The systems are designed to provide temperature profiling solutions for the contact firing, anti-reflective coating and lamination processes. These operations are all key to the quality and performance of the final photovoltaic cell and hence, module. The SolarPaq system travels through the furnace or thermal process, measuring a time-temperature profile directly from the product.

The SolarPaq anti-reflective coating system provides temperature profiles from the solar cells as they pass through the silver nitride coating process. This is typically conducted using a plasma sputtering process and users can monitor the cell temperature profile even with the plasma energised. This system has been designed so that it simply takes the place of one of the cells in the carrier, thus no modification is required to the expensive carrier.

Incorporating feedback from process engineers using the Datapaq profiling system in contact firing furnaces, the SolarPaq contact firing cell clamp is paired with custom-designed thermocouple probes to ensure accurate and repeatable measurements – the foundation for any process optimisation.

The SolarPaq vacuum lamination system is used to profile the final assembly stage of the solar modules. An all-new thermal barrier ensures that the data-logger is protected from not only the heat of the lamination process, but also the external pressure that is applied. A unique external barrier frame eliminates the risk of any stress points being created on the vacuum membrane.
