I want to use a silicon photodiode in a research project. Actually i need a photodiode "hydrogenated amorphous silicon (a-Si:H) p-doped/intrinsic/n-doped photodiode" but it's hard to find, so i search for an alternative. The alternative must or should:
1-commercial and cheap
2- Very small surface area (less than 1 mm2)
3-landa max (absorption wave length) near to 470 nm
4- Module is better than phtodiode
6- with routine voltages (adaptable to UNO)
What are UR suggestions?
My project is related to this article:
From the abstract of the article Its not clear to me whether they have used a customized Diode (the chip itself) or not. Some Integration stuff, ok, but probably an of-the-shelf diode (keep in mind that if not semiconductor specialists or even not engineering they have to use this "hydrogenated amorphous silicon (a-Si:H) p-doped/intrinsic/n-doped photodiode"-wording to appear being cool)...
Anyway: ask the authors what they have used. If a commercial one, you are done.
It's not. It's deposited silicon/H and i want to use a commercial photodiode. Forgot the article.
That description is usually shortened to PIN photodiode, and they are available commercially. https://www.mouser.com/c/?q=pin%20photodiode
For your purposes, you might consider an avalanche PIN diode (APD), which can be used to detect single photons.
U r right but do u know a tiny pn photodiode?
I think, @jremington provided all required Information to make the next step in your research(!) project on your own.
Btw: there is a counter on the provided link. It just says "one", and that was me. So it appears to me that you have not even taken his reply sufficiantly into account
Really? R they very sensitive? If u have experience, could u suggest my one which is very sensitive and tiny?
The data sheets are available at the link I posted, which you STILL have not bothered to follow.

If asking meaningless questions on the forum is the best you can do, choose another hobby.
