Wafer-based solar cell manufacturing has still proven its value in the market especially when the thinned solar cell reduced the material cost while maintaining same level of performance. One big challenge with that is the task of handling thinned and warped solar-cell.
Solar Cell Handling
Bernoulli grippers are widely used for handling such wafers. One problem is that such grippers may have trouble plucking objects that are warped, as when picking up a thin wafer that sticks to the one behind it. Innovative Robotics' thin wafer handling solution can address such issue with a new vortex+edge gripper combination. The vortex blade is designed to flatten the substrate before picking up, thus, allows up to 4mm warpage and 5mm mis-alignment (mis-placement).
