Designed For:

High School Students

Overview

The end products built by students in this module will be two of the most efficient and contemporary types of micro-fabricated solar cells. The students will have the opportunity to deposit Bismuth, Graphite, Copper, Lead Iodide* and Tin on silicon wafers and to compare the direct current generated by the microfabricated materials. The resulting hexagonal PbI2 crystal, the melted Bismuth or Tin, the attached Copper tape or the sprayed graphite deposited on silicon wafers will simulate and illustrate the various methods of microfabrication used by major corporations and academia to micro-fabricate nano-electronic devices. Through these hands-on activities they will be able to utilize a silicon wafer as their control, and compare the energy absorption of various materials as they are fabricated on a silicon wafer substrate.

After completing this module, student should be able to:

Design, build, and refine a device that utilizes the photoelectric effect to convert form of energy into another form of energy
Integrate and evaluate multiple sources of information presented in different media or formats (e.g., visually, quantitatively) as well as in words in order to design, build and refine their device.
Communicate their technical findings applied to other technological devices using the principles of wave behavior and wave interactions with matter to transmit and capture information and energy.
