Digital Learning Tools for Teaching “Alternative Solar Cells with Titanium Dioxide” (ALSO-TiO2) - A Contribution to Sustainable Development Education

The movement “Fridays for Future” is a good indicator for students not only having a very strong interest in sustainability, but also a high motivation to actively discuss this topic. For this reason, it is important for schools to provide the necessary basic knowledge and to give students insight into current research and application within the realm of sustainability education and SDGs. In this article digital learning tools for the concept “Alternative Solar Cells with Titanium Dioxide” (ALSO-TiO2) are presented, that can be used to implement the topic “Solar Cells” in regular chemistry classes. The concept bridges the gap between the galvanic cell as a compulsory subject and dye-sensitized solar cells (DSSC), also known as Grätzel-cells. Thus didactic experiments, so-called photogalvanic cells, are explored with the help of an e-book. In addition, a small eye-tracking study is presented which was carried out in order to develop a new edition of an interactive animation.
