Asked 1st Oct, 2020
In most of perovskite solar cell SCAPS simulation, Why does the value of donar density used to keep zero?
Perovskite is an Intrinsic semiconductor which comprised equal no.of hole and electrons concestration under thermal equilibrium condition. However in most of the perovskite solar cell SCAPS simualtion journal papers , only the vlaue of acceptor doping concentration given but donar density value used to kept zero. Why?

Dear Santosh,
welcome,
The perovskite material used in producing solar cells is undoped and fine polycrysatlline material. Then it is supplied by two sandwiching layers, the HTL and the ETL. These layers are then metallized to produce the electrical electrodes.
One of these electrodes is transparent. It is normally made of transparent conductive oxides such as ITO. All layers are built on glass.
What is given most probably is the doping concentrations of the the HTL and the electron transport layer. The the intrinsic concentration ni of the perovskite is calculated in the simulator by giving Eg , the energy gap and the effective density of sates Nc and Nv.
So, you gave the structure you intend one can give more specific answer if this answer is not sufficient.
Best wishes

What are the steps to query data for machine learning from Materials project using API?
I have tried the following steps, but these are giving the errors
1. !pip install pymatgen
2. !pip install mp_api
2. from mp_api.client import MPRester
with MPRester("my_api_key") as mpr:
docs = mpr.summary.search(material_ids=["mp-149", "mp-13", "mp-22526"])
And got a very long error as a result.
What am I doing wrong?
