Lesson 1
How can you squeeze electricity from a blackberry?
More than 3,000 middle TN high school students can answer this question from personal experience. They have made solar cells out of blackberry juice and measured the electrical power they produced. The students also examine the material that they used to make the solar cells with one of VINSE’s scanning electron microscopes. These instruments can magnify objects by as much as 500,000 times, enough to allow the students to see nanoscale features 50,000 times smaller than the width of a human hair and learn how these tiny features can affect how much sunlight a solar cell can capture.
