Abstract
Systems and methods for transferring solar cells while maintaining a controlled micro-environment are provided. In particular, such systems provide automated loading and unloading of solar cells by use of a conveyor and elevator within a tank receptacle sealingly connected with a solar cell carrying pods and a flow tube of solar cell components in a solar cell fabrication process. The tank receptacle can include one or more ports for sealingly and operably coupling with a cover of a solar cell carrying pod, each port having an elevator for withdrawing a removable base of the pod along with a solar cell carrying cassette into the tank and a conveyor to facilitate loading and/or unloading of solar cells with the cassette by coordinated movement of the elevator and conveyor. Such systems can further include a robotic arm having a gripper and nozzle to maintain a micro-environment within the pod during transport.
