  1. JESUS GUARDADO, LEAH NATION, HUY NGUYEN, TINA RO UPDATE  2/25/2010

  2. Agenda • Project Background • Current Progress  • Setbacks • How that affects us • Previous Schedule • Updated Gantt • Looking ahead

  3. Project Background Polymeric Photovoltaic Cells • Low fabrication costs • Light weight • Flexible Carbon Nanotubes • Aid transfer of electrons • Prevents charge recombination • Improves Voc Illustration of cell FTO - Flouride Tin Oxide PEDOT - Poly(3,4-ethylenedioxythiophene) P3HT - poly(3-hexylthiophene)

  4. Current Progress  Accomplishments: • acquire materials • find workspace • obtain permission to use equipment • modify procedure based on available equipment • create logo • consultations with staff, professors • reserve future equipment

  5. Materials Purchased and Donated     • Carbon nanotubes (CoMoCAT, Aldrich) • P3HT [ poly(3-hexylthiophene) ] (Baldo) • chloroform (Xie) • PEDOT [ poly(3,4-ethylenedioxythiophene) ] (Xie) • FTO [ Fluoride Tin Oxide ] (Xie) http://riekemetals.thomasnet.com/ SWeNT SG 65, from CoMoCAT

  6. Equipment and Labs • Equipment and Lab confirmed for nanotube prep: • 2/25 ISN (Institute for Soldier Nanotechnologies) • Ultrasonicator • Super Speed Centrifuge • wanted: rcf= 164,000g • got: 70,000g • Impact of available equipment:      modify procedure • different ratio P3HT to CNTs • lower PV response nanopharmaceuticals.org

  7. Setbacks and Challenges Setbacks: • Delays in obtaining materials • Primary lab choice: inaccessible • Secondary lab option: inadequate equipment • Long-distance communication issues •   Immediate Challenges: • Securing access to ISN equipment • Adjusting to a changed protocol and schedule http://www.uwyo.edu/EHS/images/jpeg%20images/detour_sign.jpg

  8. Previous Schedule

  9. Updated Schedule

  10. Milestones

  11.  Research

  12. Experiment

  13. Upcoming Tasks: • Create samples: Prepare nanotube materials, prepare mixtures for samples, spin coating • Continue research on future potential of PPCs • Prepare strong final design strategy for next presentation

  14. Summary The harder the conflict, the more glorious the triumph. What we obtain too cheap, we esteem too lightly; it is dearness only that gives everything its value. I love the man that can smile in trouble, that can gather strength from distress and grow brave by reflection. 'Tis the business of little minds to shrink; but he whose heart is firm, and whose conscience approves his conduct, will pursue his principles unto death. -Thomas Paine
