PIN Photodiode || Pin Diode.

In this lecture I explained about the full concept of Pin photo diode this are following outlines:
1.Working of PIN DIODE
2.Structure of PIN DIODE
3.Construction of PIN DIODE
4. Applications of PIN DIODE
Pin photo diode(or)Pin diode(or)Pin photo detector, which works like a Photo detector when it is connected in Reverse bias.

Thank you.

Could you explain the advantages of the PIN diode over the PN diode?

[@itsfactssai364]

Can I write what u said in sem exams ? If write what u said will they give marks..

[@marepallypradeepkumar5537]

Definitely, you can.

[@ywk7282]

Thank you for the video may I ask a few questions?
1. If I understood it correctly, e h pairs are generated by the light, and charge seperation is done by the electric field in the i layer? If that is true if the electric field was low they would be seperated and recombined again??
2.The key is the light to the intrinsic region the picture look like it hots the p+region only. The core point is light hitting the “big” intrinsic region right?
3. In the formula when you say Ip=qNe is Ne the doping concentraion in n+p+region?? I am not sure what exactly is Ne
Thank you for the lecture😲😲

[@marepallypradeepkumar5537]

Thanks for your thought provoking questions. I have address them below.
1.Electron & Hole pairs are generated by light, which are seperated by high Electric field only.
2.Light hits the intrinsic region of the PIN diode. Due to the energy transfer between charge carriers and photons, charge carriers are generated or released/emitted out from parent atoms.(if incident photon has energy greater than the band gap energy of semiconductor). This produces photo current(Ip).
3.In formula,
The generated Photo Current, Ip=q.Ne
q - Electron charge,
Ne - Carrier number or concentration.

[@spyy7804]

What is the difference btw pin and solar cell then ?

[@marepallypradeepkumar5537]

PIN Diode & Solar cell are primarily differ in their Construction, Principle of Operation, Time of Response, Efficiency and Application.
PIN Diode (Small in Size) can be used as Photodetector & Solarcell (Large in Size) to generate electricity.

[@edmondo785]

Free electrons not going to n+ side?

[@marepallypradeepkumar5537]

As PIN diode is connected in Reverse Bias, electrons will drift towards n+ side only.

[@foodrouteswithsonu]

anod is the +ve terminal. cathod is negative terminal , but you have written it opposite and connected the circuit 2:54

[@marepallypradeepkumar5537]

PIN Diode should be connected in Reverse bias.

[@foodrouteswithsonu]

@@marepallypradeepkumar5537 thankyou sir

[@behealthybefit681]

Sir, u said, when light falls on pin diode electrons will generate, but where light or photons will fall? On P region or n Region or Intrensic region? Bcz in pin diode light or photons will fall first on p and layer. Can u please elaborate little

[@marepallypradeepkumar5537]

If light of sufficient energy falls (or) reaches the Intrinsic region then due to the interaction between photons and atoms (semiconductor) electrons are generated.

[@behealthybefit681]

@@marepallypradeepkumar5537 so it means, photons falls on pn layer and then it reaches the Intrensic region and then it interacts with atomes present in the intrensic region? And then electrons generates? But first it will fall on pn layer so that time what will happen?

[@marepallypradeepkumar5537]

@@behealthybefit681 The probability of electron generation is very low in P&N region.
So,to increase the number of electrons an intrinsic layer is inserted between P & N regions.

[@Surya-uv3bz]

cathode is negative terminal right? but you wrote it as positive

[@marepallypradeepkumar5537]

Watch it again, I said cathode is *connected* to positive terminal.
I didn't said cathode is a positive terminal.

[@Surya-uv3bz]

So the cathode and anode u are mentioned is n , p terminals right??

[@marepallypradeepkumar5537]

Exactly

[@sambamanisha6595]

Hello sir could you explain photo diode also

[@rohithagiru7380]

IS PIN diode and PIN photo diode both are same ? Are not ?

[@marepallypradeepkumar5537]

Yes,both are same.

[@cohental2000]

can you please explain why reverse bias is needed? can you use no bias?

[@marepallypradeepkumar5537]

To increase the availability of area in Intrinsic region for capturing light,which generates more number of electrons and holes & this happens only in Reverse bias.

[@maheshb3976]

Good explanation
Pradeep sir...

What is difference between PiN photo diode and Pin photo detector ? Are they both are same ? Sir

[@marepallypradeepkumar5537]

Both are same.
PIN Photo detector is fabricated with Diode

Hello sir, at 5:14, isnt that electric field of the depletion region will head into the p+ side, so the electrons generated by the light will go into n+ side?

[@marepallypradeepkumar5537]

As PIN DIODE Connected in Reverse Bias electrons will drifts towards n+ side only.
