Presentation Goal
• To present path taken to final design• Detail each subsystem• Validation of concept through testing• Present path forward
Background Information
• PV solar panels• Buy pre-made
silicon wafers and assemble at plant
• Want to produce their our wafers
Current Method
Current Method
Project Definition
• To enhance the silicon powder dispensing method for the use in PV solar panels:– Automate dispensing of silicon– Design a support structure
Specific Wants
Technical Performance Measures
• Level of automation• Convenience of use• Simplicity of device• Shape/Size• Stability
