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

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

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

4. Current Progress Accomplishments: o acquire materials o find workspace o obtain permission to use equipment o modify procedure based on available equipment o create logo o consultations with staff, professors o 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: o 2/25 ISN (Institute for Soldier Nanotechnologies)  Ultrasonicator  Super Speed Centrifuge  wanted: rcf= 164,000g  got: 70,000g Impact of available equipment: modify procedure o different ratio P3HT to CNTs o 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 http://www.uwyo.edu/EHS/images/jpeg%20images/detour_sign.jpg Immediate Challenges: Securing access to ISN equipment Adjusting to a changed protocol and schedule

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
