Actually, pretty awks for your PhD teacher when he is incorrect.
Solar cells use the photoelectric effect, but they are different to photoelectric cellsLooking through my textbook. It says "A photocell is a device that uses the photoelectric effect. These devices include photovoltaic, or solar cells."
Much easierbasically i wrote: a photocell consists of an anode and a photosensitive cathode in a highly evacuated glass tube. When light of a frequency higher than the cathode's threshold frequency strikes the cathode it emits free electrons by the photoelectric effect. The electrons are accelerated as a focussed beam towards the positive anode due to a applied potential difference, this initiates a photocurrent. The current can be amplified to do work in an external circuit; e.g. power a lamp.
Isnt photocells easier than solar cells?
Lol. I hope the Board of Studies don't accept both. It gives me a slight chance to get a Band 6.Actually, pretty awks for your PhD teacher when he is incorrect.
Have a look at where that the dot point concerning photocells in the syllabus.. Before semiconductors..
I wouldnt be surprised if they end up accepting both
Yeah, wtf? I love projectile motion. At least there were loads of calculations.No projectile
Wow. I do Age of Silicon and didn't even know that the structure is different.Photocells are pretty much the thermionic equivalent of solar cells.
It consists of 2 electrodes embedded within a vacuum tube. A large cathode covered in photosensitive material, from which photoelectrons can be emitted when subject to sunlight.
2014 HSC 3 marks:If jacaranda is saying that photocells includes solar cells, and many students write about solar cells because photocells don't get taught (I learnt photocells as being solar cells), then surely something would have to be done?
