    Great vid, thank you! Two things are confusing me though:
    How do holes move across? Isn’t a hole just the lack of an electron?  By saying holes move across does he actually mean that holes are formed on the N type side because electrons are moved to the p-type side?

    Why does the equilibrium stop within a limited region and not throughout? i.e. what stops the electrons adjacent to the positive region moving into it?

    Thank you for any help!

    i always got to the point of understanding the PN junction but somehow not how to get a current out of that…three minutes of your video and everything is clear to me. thanks guys!

    im always wondering since electrons move to the bulb light doest it vanish? i mean there is an amount of electrons and photons is a cause that moves electrons not bring another one from the sun

    Can someone explain to me how the holes cross the depletion region?

  5. daeser1 on December 16, 2019 at 4:08 am

    A verbal explanation would be nice. Why don’t ions from both sides move across the junction until it reaches an equilibrium state (neutral)? What is stopping this from happening?

    1:46, saying that the holes wander across the junction leaving behind static -ve charges is being redundant. Once the electrons move across the junction from n-type to p-type, static +ve charges r left behind due to ionization of the atoms the electrons came from. Now at the same time as those electrons fill up the holes on the other side, the atoms with the holes filled, now possess a -ve charge, therefore creating an excess -ve charge in the p-type semiconductor.

    How does a copper-copper oxide semiconductor-junction solar cell work? is it the same as laid in this video or is it different?

  8. New Physicist on December 16, 2019 at 4:12 am

    Beautifully done. Here’s me explaining the exact principle in my own way, watch and comment… https://youtu.be/WfP5YdJn-c4

    the fact that there is no sound renders the video " inutile pour le debutant. pardon met suivant le son".

  10. Jon Sm on December 16, 2019 at 4:12 am

    why do the electrons that dislodge from sunlight always come from the depletion zone? why not from either the N or P sections?

  11. محبة وسلام on December 16, 2019 at 4:13 am

    stunning 

  12. محبة وسلام on December 16, 2019 at 4:13 am

    any help please, the videos states that the electron hole pair generated at the junction while as i have been read about solar cells the e-h pair generated in p side.

  13. Muhammed Sami on December 16, 2019 at 4:14 am

    Please
    Why NA Greater than ND in p n junction????

  14. Himani Dhawan on December 16, 2019 at 4:15 am

    such creativity is awesome and it has cleared all my doubts …. this is an underrated channel I think … it should have more subscribers… thank you.

  15. Arid on December 16, 2019 at 4:15 am

    Is there any difference in the manufacturing of a pn junction diode and a photodiode? Besides the outer shell being transparent to allow light etc. I mean in the semiconductor part itself. Also must the light be incident on the junction itself? I think light can be incident anywhere on the diode. Yes?

  16. Shanta Hsieh on December 16, 2019 at 4:15 am

    You can find perfect idea for that on Avasva Solutions website.

  17. Ashish Kandola on December 16, 2019 at 4:15 am

    it’s great way of teaching,
    hoping my school would use it one day,lol

  18. PRAVEEN GUJJAR on December 16, 2019 at 4:15 am

    Nice thanks love u

  19. abusadamajd on December 16, 2019 at 4:15 am

    Fucking GREAT !!

  20. PRATAP SINGH on December 16, 2019 at 4:16 am

    nice explaination……………thankks

  21. Shantel Bollmann on December 16, 2019 at 4:19 am

    Take some info about energy on Avasva . It was very helpful to me 😀

  22. Oskar Jankowski on December 16, 2019 at 4:21 am

    Amazing, very helpful video!

  23. qinglin yu on December 16, 2019 at 4:26 am

    It’s really helpful in understanding how a P-N junction solar cell works. Help me a lot. Thanks very much.

  24. Easter Stedman on December 16, 2019 at 4:27 am

    I took great plans from Avasva . It help me a lot with my own solars.

  25. Nash Shrestha on December 16, 2019 at 4:29 am

    Why don’t the static ions absorb light thereby releasing carriers? Also, when carriers are generated in the depletion region, the electric field causes the electrons to go toward the n-region and the holes to go toward the p-region. Now, before the electrons can get to the n-region, they have to get across the positive ions. Likewise, before the holes can get to the p-region, they have to get across the negative ions. Why is it that these charge carriers not get absorbed by the ions? I.e. as the charge carriers are moving across the depletion region, the ions should absorb at least some of them so that the ions turn back into atoms. Why doesn’t this happen?

  26. Danish Mahmood on December 16, 2019 at 4:30 am

    very helpful, explained clearly, diagrams relevant and intuitive. No other video explains as well as this.

  27. MITHOON KUMAR on December 16, 2019 at 4:34 am

    Awesome video 🙂

  28. Shannan Schisler on December 16, 2019 at 4:34 am

    I did it with Avasva plans.

  29. Bernardo Sampaio on December 16, 2019 at 4:36 am

    Awesome simple explanation, very enlighting animations and clear text!

  30. Clécio Nascimento on December 16, 2019 at 4:37 am

    NICE!!!

  31. Abyss Walker on December 16, 2019 at 4:38 am

    thanks this video helped a lot.

  32. good boy on December 16, 2019 at 4:38 am

    is it possible to follow the same steps without silicon.

  33. Vinh Ngo on December 16, 2019 at 4:38 am

    what drove the electrons to go through the externa circuit near the end?

  34. Baba Rajeev Kumar on December 16, 2019 at 4:39 am

    Great work !! simple to understand but there is small mistake. HOLES never come out of the bond into the external wire then only travel in bonds.Other mistake is electrons that travel in doesnt support current.Only free electrons support conduction.Thanks you

  35. Technical Address on December 16, 2019 at 4:41 am

    Verry good sir g

  36. zeeshan babar on December 16, 2019 at 4:42 am

    i am totally confuse how it works when ntype and ptype are attached holes from ptype move in ntype and electrons go to ptype due to this process a space charge region is created now no electrons cross the juntions means electrons in n and holes are in ptype so what happens when light strikes to n and p material does electrons cross the space charge region like diode when they r forward biased or they dont cross the depletion region

  37. Rutuja Risbud on December 16, 2019 at 4:43 am

    Thanks for the video, i found it very helpful 👍

  38. Jitendra Razz on December 16, 2019 at 4:46 am

    very nice

  39. ila ila on December 16, 2019 at 4:46 am

    its quite nice watching a silent movie – it is silent isn’t it?

  40. Shannon Amend on December 16, 2019 at 4:46 am

    With Avasva plans doing something like that was easy.

  41. Syed Abdul Majid Ali on December 16, 2019 at 4:46 am

    nice work really help me in understanding

  42. PRAVEEN GUJJAR on December 16, 2019 at 4:48 am

    🔕 Silence gives u knowledge in better way again thanks

  43. Pasha Haletskiy on December 16, 2019 at 4:49 am

    I’ll use Inplix instructions to make it by myself.

  44. Carmelina Katzman on December 16, 2019 at 4:49 am

    If you like to make your own energy you should go to Avasva

  45. Sunwakka on December 16, 2019 at 4:49 am

    this will save me on that test

  46. Varun Mittal on December 16, 2019 at 4:50 am

    The way of explaination was pretty good

  47. Stuart Keating on December 16, 2019 at 4:54 am

    Hey man. Great job! Which program did you use to make and animate all this?

  48. Raşit Taşdelen on December 16, 2019 at 4:54 am

    the clearest animation ever! thnks a lot..

  49. Shanta Hsieh on December 16, 2019 at 4:57 am

    I made it myself thanks to INPLIX website

  50. Ali Raza on December 16, 2019 at 4:59 am
