Question

1. The operation of a solar cell is based on the photovoltaic effect. What is the photovoltaic effect and describe the fundamental processes behind this effect? B) Demonstrate these processes using schematic drawings for a Si solar cell.
2. Draw the band diagrams for the solar cell under forward bias and illuminated conditions.
3. Sketch the I-V characteristics under dark and illuminated conditions for a Si solar cell.
4. What are the key external parameters for a solar cell and how are they determined. B) How do these parameters for a Si solar cell depend on temperature? C) Give some typical values for these parameters for commercial devices.

Explanation / Answer

a method of generating electrical power by converting sunlight into direct current electricity using semiconducting materials that exhibit the photovoltaic effect. A photovoltaic system employs solar panels composed of a number of solar cells to supply usable solar power. Power generation from solar PV has long been seen as a clean sustainable[1] energy technology which draws upon the planet
