1. Solar Cell Fundamentals Lab All safety rules to be followed at all times Full gowning is required when working in the clean room The clean room will only be available certain times Students must sign-in and sign out of the clean room for credit Students must meet the minimum hours per week in the clean room Students can work together but each student must fabricate their own solar cell

2. Solar Cell Fundamentals Lab Each student will fabricate their own solar cell The traveler must be strictly followed and filled out – this is both a record of completed steps and source of processing information for analysis At key steps in the process, as shown on the traveler, I will need to inspect or verify a completed process Precisely following the traveler will result in a good solar cell Each student must fabricate a good solar cell for an “A”

3. Traveler example

4. Solar Cell Fundamentals Lab All process steps have procedures listed and available on the web site Students are expected to be able to do clean room processes from these procedures ( with help from myself or the TA) By the second fabrication, students are expected to do all processes without help

5. 6 cm x 6 cm solar cell fabricated in the Cameron clean room Bus bars need to be thicker

6. Solar Cell Fundamentals Lab The first cells must be completed in 5-6 weeks from the start You must fabricate and test an acceptable solar cell and have it verified by me At key steps in the process, as shown on the traveler, I will need to inspect or verify a completed process

7. Solar Cell Fundamentals Lab A completed and accurately filled out traveler will be submitted at the end of the first cell fabrication for grade A second solar cell fabrication will be done varying one key fabrication element to see if it improves performance. The final report will detail the fabrication, results, and comparison of the two fabrication runs.
