In this green chemistry lesson plan, students will build and test their own dye-sensitized solar cells using dye from blackberries. Along the way, they will learn about the principles of green chemistry and evaluate how solar cell manufacturing can go green. Consider this process against the twelve principles of green chemistry.
Hand out the Student Background Worksheet. Have students read article #1 (How Green Are Those Solar Panels, Really?) independently or read it as a class. You may also want to assign this article as homework reading prior to class. Discuss the article and ask the students what they now think about solar panels.
This is because traditional solar cells are expensive and inefficient (typically 11-18% of the sunlight they absorb is converted to electricity). To be considered a green chemistry technology, the technology must demonstrate three standards: performance, safety, and cost benefits.
Instruct students to study the Reading Passage, “Introduction to Photovoltaic Systems,” and complete the questions and vocabulary. This activity will help them learn about PV systems and some of their applications. Key vocabulary words in the Reading Passage will assist them in understanding the Lab Activity instructions.
Solar energy, or energy from the sun, is a free, readily available, plentiful resource that can be collected by solar cells to generate electricity. Although solar cells have been around for a long time, their use for energy generation is not widespread.
Concentrator cells: A higher light intensity will be focused on the solar cells by the use of mirror and lens systems. This system tracks the sun, always using direct radiation. MIS Inversion Layer cells: the inner electrical field are not produced by a p-n junction, but by the junction of a thin oxide layer to a semiconductor.
