Lesson 4.2 – Dye-Sensitises Solar Cells
In this lesson students will:
- Extend their understanding of solar cells and dye-sensitised solar cells in particular.
- Complete a second-hand data task relating to the efficiency of dye-sensitised solar cells.
- Dye-sensitised solar cells and investigate the principles by which they work.
- The elements of a good research article which clearly communicates relevant information which is age appropriate to the reader.
Learning SequenceShow all resources
Welcome students and briefly review the key ideas about the construction and operation of solar cells from the previous lesson using key questions.
Discussion – Revise the key principles in operation of traditional photovoltaic solar cells through the use of the YouTube Clip – How Photovoltaic Cells work and L4.2 Solar Cells.pptx. Resources
Investigation – Teacher introduces the 2nd Hand data analysis task. Students are provided with an explanatory task sheet L4.2.1 which describes how to write a journal article intended to inform the reader about the operation of dye-sensitised solar cells. Resources
Teachers take questions allowing students to clarify the 2nd hand data task.
Investigation – Teachers then use the green screen to load an example of a well-constructed research article and highlight the effective elements which enhance communication. Use an example of an outstanding research article developed by students in previous units.
Students are then directed to work on the 2nd hand data task for the remainder of the session.
Teachers monitor student progress and answer questions.
Students to work on the development of their journal articles using the 2nd hand data task resources L4.2.1 and L4.2.2.
