Silicon, Semiconductors, & Solar Cells: Crash Course Engineering...

Today we’re looking at silicon, and how introducing small amounts of other elements allow silicon layers to conduct currents, turning them into semiconductors. We’ll explore how putting two different types – N and P semiconductors – together gives us electrical components like diodes, transistors, and solar cells.

Crash Course Engineering is produced in association with PBS Digital Studios:

    Quick reminder to everyone wanting to ask about Marie Curie, one of her Nobels was in physics, the other was in chemistry.

    Woohoo, this is a really good class on BJT's (Bipolar Junction Transistors) and MOSFET's, and solar energy. And I really like this girl! She is so skinny and tall and smart! Maybe she can talk about the "small signal model" next time! If your are as cool as I am, do the "small signal model" next time and what the larger and complex reality that this model represent!

    Gracious, gracious, gracious!

    Anything computing uses unipolars, because controlling by field, not current, but I get you'd need another video for explanation of those.

    You don't need to dope silicon to make it conductive. That is just done to change the band structure. Silicon by itself is a semiconductor.

    Does this channel provide any "Try this at Home" Experiments?

    Your videos are awesome, and these videos were the reason I passed my physics final. Have you guys considered partnering up with the AAMC to make videos geared towards MCAT review?? I would love to watch your videos to review for that content

    I have to say that's one of the best explanation of transistors, with this explanation one can slowly but surely build up their knowledge in what is arguably the most important electrical component of our time

    Why don't we use sulphur in n type semiconductors for better current or do we?

    doping: the enhancing of a semicomductors conductance by the altering of the net positve or negative charge by injecting an impurity.

    And thats just in electronics, because optics is also effected. And biology to.
