  1. Solar Cell Fabrication Process Comparison For final PP report

  2. Solar Cell Top Contact design used for this comparison Cell size: 2.19 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
