PV Cell Solar Simulation Test System
Our customer needed a machine that could handle, test, and sort two different sizes of photovoltaic (PV) cells at a high throughput rate.
A robotic transfer device, with a vacuum end-effector, was used to load and unload the test nest and place graded parts in the appropriate output stack. To ensure that each cell was tested under the same temperature conditions, the staging nest and test nest were liquid chilled. An infrared temperature probe measured the actual cell temperature just prior to testing. Cell thickness data was also obtained. A color graphics display put up easy-to-read process trend data.
