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:
