As we know bandgap of metal halide perovskite can be tuned by varying the A, B, X sites in perovskite.(mainly by the x site variation ) Is there a similar varition of the electron affinity of the perovskite material by tunning the sites? kindly share the related studies as well.
thank you.
Do you mean the Methyl Ammonium Lead Iodide or some other hybrid Perovskite halide?
I meant in general about metal halide perovskites family. But if there is a explanation only in case of MAPbI3 I like to read about it.
Thank you.
There are plenty of Literature available about the Halide Perovskites since they are well known for their application in Solar Cell with High efficiency. The A atom may be any transition metal and B position (body centered) is occupied by some organic cation molecule and the linking from one metal to another metal is through the halogen atoms.
The ABX3 family Perovskite are little different from the above, here also transition metal atoms like Mn, Co, Ni and Zn occupies the corner position (0, 0 ,0), these metal atoms are connected by a formate (HCOO) anion and the body centered position (0.5, 0.5 0.5 ) is occupied by dimethyl ammonium cation.
if you search there is a plenty of literature available for both the perovskites.
All the best.
