  1. SAVE THE BUT… HOW?

  2. Solar Energy!

  3. What about feasibility? • Today’s solar cells aren’t good enough!

  4. We have to save the world.

  5. Here’s how.

  6. Presentation by Valerie Ding

  7. What does that even mean?

  13. Now we understand the title!

  14. Moving on…

  15. Their Materials • CdSeS quantum dots + TiO2 substrate = quantum dot solar cell • (1) Make the quantum dots! • (2) Deposit the quantum dots onto TiO2! • (3) Design and make the solar cell!

  16. Their Research Goal • “Test the concept of a rainbow solar cell” • Examine “the influence of Se:S (selenium to sulfur) ratio in tuning…quantum dots” Arainbow solar cell is able to harness much of the wavelengths in visible light and more. Image courtesy Inhabitant.com

  17. ANALOGY TIME

  18. Their Findings Selenium to sulfur ratio affects the colors that the quantum dots emit At right is the proposed multilayer quantum dot solar cell. FTO = flourine doped tin oxide

  19. Their Findings

  20. So what? • That is always the question. • Santra and Kamat have determined important correlations between quantum dot material and photovoltaic performance that can bring quantum dot solar cells to the next level. • …Saving the world!

  21. That was a mouthful.

  22. Much more to improve…

  23. Let’s get to work.
