Students’ use of resources in understanding solar cells

We use the framework of conceptual and epistemological resources to investigate how students construct understanding of solar cells - a complex modern physics topic that requires mastery of multiple concepts. We interviewed experts and novices about their understanding of the physics of solar cells, and examined their responses for evidence of resources being activated. We used this information to create a unit dedicated to the physics of solar cells at the advanced undergraduate level, which we then implemented. Based on the patterns in the interviews and student responses in the classroom during the unit we can hypothesize what resources students draw on when they are trying to understand the complex physics involved in the functioning of solar cells.
