Description:
This lesson is designed to be completed in two 80-minute sections. The teacher will show a basic procedure and video. The teacher will facilitate the construction of Organic Dye-Sensitized solar cells on coated glass plates with Titanium Dioxide. A fume hood with outlets for electric hot plates must be used for the first part of the construction. On Day 2, Teachers will facilitate final solar cell treatment and solar cell testing indoors and outdoors. Teachers should be knowledgeable of the Titanium Dioxide / Berry (anthocyanin) solar cell electron transfer mechanisms.
- Day 1: Introduce procedure and bake titanium dioxide onto coated class slides
- Day 2: Further treatment of slides, assembly of solar cell, and testing
