- Applet to form a pn-junction: You can adjust parameters such as doping consentration and which type of semiconductor material, while you look at how the bandgap, fermilevel and diffusion length changes http://jas.eng.buffalo.edu/education/pn/pnformation2/pnformation2.html
- Applet which shows generation and recombination: This applet "vishiolizes" were good how electrons and holes are created and annihilated through a valens and a conduction band and a trapped state http://jas.eng.buffalo.edu/education/semicon/recombination/indirect.html
- Solar cell design calculator: Design your own solar cell by doping the semiconductor, choose the area, serial and paralell resistance, generation rate and temperature http://jas.eng.buffalo.edu/education/pnapp/solarcell/index.html
