Abstract
It is important for citizens to get interested in science, energy, and environmental problems in order to be able to make scientifically sound judgments. For the purpose of this activity we have chosen the example of dye-sensitized solar cells. Although dye-sensitized solar cells are known as a handmade experiment, they still require high-technology such as nanotechnology and have a very high cost. We have invented dye-sensitized solar cells with materials that are closely used in everyday life. The efficiency of the dye-sensitized solar cells is lower, but it is possible for citizens to make handmade dye-sensitized solar cells by themselves. We expect this invention will generate increased interest in science, energy, and environmental problems and aid citizens in making more scientifically sound judgments.
