SolarPaq® for Anti-reflection (Sputtering) Coating Process
A Complete Solution
The custom designed logger DP5663 and its thermal protection are easily placed into the cell carrier. This design enables the system to occupy one of the 156 mm (6.1 in) positions, so there is no need to modify the carrier. The system then passes through the entire process with plasma fields energized, and on exiting the process, the temperature profile information can be downloaded and analyzed. The system has been specifically designed to withstand harsh thermal and electrical environments within the plasma chamber, and can be used repeatedly for both process set-up and regular monitoring. The Datapaq system can pass through the entire process measuring temperatures of the cell surface, thus providing data on what is happening at all points inside the process.
Datapaq DP5 Data Logger
The Datapaq DP5 range of loggers is intended for use in short and medium duration thermal processes; the design is optimized for low height and fast reading capabilities. The Datapaq DP5 has been designed to ensure minimum cost of use and achieves this by making use of ‘off the shelf’ charging and communication leads. In addition all of the Datapaq DP5 loggers feature a rechargeable and user replaceable NiMH battery pack, combining ease of use with lowest running costs. The user replaceable battery charges from flat to usable in just five minutes. A full charge takes only 90 minutes and can provide 20 profile runs.
Thermal Barriers
The VB7400 makes use of a unique reflective plate insulation technology. This guarantees there is no outgassing from the profiler system so ensuring the process runs under normal conditions.
Software Insight
This all new software has been designed specifically for use within the photovoltaic (PV) solar industry and contains many process-specific analysis displays. Wizards guide the users step-by-step to quickly obtain the data and analysis of the required results. This ensures that both experienced and novice users can obtain maximum benefit in the shortest possible time.

The Datapaq® SolarPaq system has been designed to monitor the product temperature profile as the photovoltaic (PV) cells pass through the plasma coating process. Working with major equipment manufacturers, a profiling system has been designed that can pass through the process chambers, measuring the cell temperatures even with the plasma activated. This feature, combined with the unique ability to be slotted straight into an un-modified cell carrier, enables profiling to be conducted without disrupting normal production.
