Construction & Working of a Photodiode - Optical Devices

This EzEd video explains the Construction& Working of a PHOTO DIODE
1) Operated in Reverse Bias Mode
2) Reverse Saturation Current - Photo Current
3) Dark Current
4) Advantages & Disadvantages of Photo Diode

Saved my time

[@ranjanasawarkar5717]

Thank you so much can't thank you enough to clear my doubt about reverse bias

[@bittu07kumar]

Than u so much..... all doubts clear after watching ur video

[@rakshitbadiger8771]

Very best explained

[@thetechnician8017]

I would like to build a fire alerting system using a photodiode and my point of concern is on how can I build it in a way that the photodiode responds to fire threats but not other threats like light being emitted by torches, bulbs, LEDs and others of that sort.

Pro trick: watch movies on flixzone. I've been using it for watching loads of movies lately.

[@sharfuddinkhan9835]

Well,i think with fire 🔥 smoke should also be detected,so,you will need an IR sensor also

[@GoldenEducationBD]

Really good

[@clg_gurl]

Thank you so much you clarified all of my doubts.

[@reshmikachristopher7783]

Thankyou. Well explained!!!

Why the electron hole pair is generated?

[@richajaiswal6766]

Thank u sir

[@nishanthvm8552]

Thx a lot sir

[@kindintiudaykiran2426]

Thanks

Does it produce any current without bias? What happens if we just connect a PD to a resistor and shine the light to it? Does the current flow through resistor?

[@aravindansundaram4010]

I think same concept as forward bias. There will be a current >>photocurrent thus not detectable.

[@souravkun719]

Nice

[@patrickschwarzenecker670]

why is there a voltage source? th photo diode creates curren-> current source

[@rajeshwarimaladakar1123]

Why electron hole pair is generated

[@mohdiqbal572]

Which diode works on the principle of photoelectric effect

[@mansiverma2066]

Solar cell
Because it is a electrically device which converts solar or light energy into electrical energy . Basically it is a pn junction diode👍
