Dye-sensitized solar cells (DSSC) are solar cells inspired by photosynthesizing plants. They have many advantages over conventional silicon solar cells, which require energy intensive processes to create. DSSCs are generally considered much more environmentally benign to produce than conventional solar cells because they use relatively non-toxic materials that require little energy to manufacture. In this lesson plan, students learn how to produce electricity by constructing a dye-sensitized solar cell at ambient temperatures, using a few simple materials. The lab offers an excellent hands-on illustration of a biomimetic technology and has been used successfully with students in upper elementary grades to undergraduates in college.
Lesson plans for the lab are provided in both English and Spanish geared toward high schoolers in 10th-12th grade, and home schoolers in upper elementary grades through high school. Lab kits containing everything you need may be ordered from the Institute for Chemical Education.
