Transferable/Scientific Skills Developed
• To know the reason why silicon is used in pv cells • To know how P-N junctions work • To know the limits of pv cell efficiency

• General aims o To show students the tight interaction between theoretical science and everyday power needs, and how high level studies can solve problems crucial for mankind o To learn to analyse all different aspects of a problem and to focus attention on the most critical ones which need to be improved • Linguistic aims o To increase students’ capability to extract information from short documentaries in a foreign language. o To learn to describe with scientific language the conversion of light into electricity o To practice the impersonal language to speculate about scientific topics. • Subject specific aims o To understand energy transformations and efficiency of these transformations o To learn that differences in ground insolation depend on geographic latitude o To realize that it is important to store the excess of energy during the day, as solar energy cannot be generated during the night o To realize the existence of photons and electrons and their interaction o To learn electron deficiency can be considered as a positive charge o Target group age: 15-16 o Level of competence in English (CEFR) B1 o Time required to use the resource with the students 3 hours o How to use it o Watching the video, after a general explanation about the structure of the atom and the properties of silicon, explain how it is possible to drug it using its neighbour atoms in periodic table. o Stimulating the discussion between students in order to focus their attention on which aspects of pv cells are critic and are to be improved to make them a valid, competitive method to produce energy. o Possible difficulties for the students o understanding the mechanism of production of electricity, the origin of the electric force which accelerate electrons in P-N junction. o understanding the corpuscular nature of light, as made of photons
