Can you help me with answering to these questions?
1. Amorphous silicon has quite different properties to those of crystalline silicon. Why does amorphous silicon have a narrower spectral bandwidth (nm)?
2. How does a typical solar cell differ from a Shockley diode?
3. Why do short wavelength photons generate a lower photocurrent than longer wavelengths?
4. Amorphous silicon is fundamentally more efficient at absorbing light, compared to crystalline silicon. Why should this be?
5. Name the limiting factors that affect the absorption of sunlight by a solar cell.
6. Explain briefly how each of these limitations affect the potential photocurrent?
