Introduction
The Photo-electric Effect -the releasing of electrons from the surface of a metal by high energy EM radiation.

YouTube VideosThis is a useful introductory video describing the Photo-electric effect and the mathematical relationships that describe it
This video uses a free online simulation to explain the photoelectric effect (see Useful Resources PheT link)
For an explanation of why light slows down now that we have know about photons
High Powered Solar CellsThe resources above are a good place to build an understanding of the photoelectric effect from which you will be able to explain how solar cells work. You will also need to compare the different types of solar cell and critically evaluate them for application in New Zealand.
If you can get over the voice and electronic musik, this is a useful overview of how Photovoltaics work
This is a good description of the photovoltaics at the atomic level
This is a useful video looking at recent Australian innovation
This video has some interesting stats on the efficiency of different types of solar cells
Useful Solar Cell Websites
The NASA Science website has a good introduction to How PhotoVoltaics Work The How Stuff Works website is a useful to how solar cells work The Thin Film Solar Cell section is particularly useful |
