Protecting the climate by increasing the share of energy from renewable sources, such as solar energy, has become a central goal of the EU. Hence, this contribution presents approaches to implement this important topic into chemistry education. It first summarizes the working principles of silicon and perovskite solar cells and describes the potential of combining them within a so-called tandem solar cell. We then present an experiment suitable for student laboratories in which a working perovskite solar cell is constructed using anodically oxidized titanium and copper(I) thiocyanate coated FTO glass as electrodes. The self-built solar cell is also experimentally compared to commercially available silicon solar cells. Finally, we provide practical suggestions for covering solar cells in chemistry classes.
