the solar cell was upsidedown right? Bit weird question, is that why the top p type layer was transparent. Any comments.
it just requires some understanding of semiconductorsnook said:my teachers appealing about this question- apparently that point was removed from the syllabus when it was revised. He photocopied a copy of both the syllabuses and sent them to the board. He was really spewing! More than any of us... lol...
ur teacher is obviously spewing because he didnt teach u that part. teachers fault not boardsnook said:my teachers appealing about this question- apparently that point was removed from the syllabus when it was revised.

Oh get fucked.SeDaTeD said:You had to pick up that the light is able to liberate electrons from the n-type because it was able to shine through the transparent p-type layer.
yeh .. i was trying to forget the exam.. but you just made me remember that dodgy question, i thought it was upside down too... but since the p type was a thin sheet i just crapped on that the rays still infiltrated the n type and the electrons passed through the crystal lattice of n-type and their excess energy after they have passed into the holes of the p-type goes around the circuit.. or somthing...Komaticom said:Yeah the solar cell was upside down town.
I assumed that although the p-type is electron deficient, light can still liberate electrons, causing LOTS of electrons from n-type to fill holes, blah blah you know the procedure.
