1 Solar Cell Fabrication Process Comparison
For final PP report

2 Solar Cell Top Contact design used for this comparison
Cell size: cm x 7.14 cm

3 Variable for process fabrication
Fab 1 – Aluminum top conductor Fab2 – Cr/Au top conductor

4 Fab 1 – I/V curve

5 Fab 2 – I/V curve

6 Table summarizes the results

7 Conclusion The Cr/Au top contact metal did not improve performance
The Cr/Au top contact metal significantly reduced performance Possible cause of decreased performance – Cr sub-layer required for gold adds resistance to conductor
