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

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”

Traveler example

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

6 cm x 6 cm solar cell fabricated in the Cameron clean roomBus bars need to be thicker

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

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.
