Dear Mahmoud Fekry ,

welcome again!

I do not know the syntax but I can give you a tip how to build your material.

You can build it either by doping after deposition or by mixing before deposition.

What is important for you is the description of the material properties such as the

doping, the carrier concentration, the mobility, the dielectric consatnt , the energy gap and the absorption coefficient. These are the required properties rather than the molecular structure.

Dear Mahmoud Fekry,

Your solar cell structure has a problem to inject electrons or holes from electrodes due to the mismatches of work functions and organic semiconductor energy levels.

Do you mean the structure should be ITO/PEDOT:PSS/P3HT:PCBM/Al or Ag?

Dear Mahmoud Fekry ,

Hope you are well!

Why do you want to introduce a an extra nanoparticle layer?

What is failing for you is a hole transport layer but all layers are available except the hole transport layer.

Before you add a layer you have to assign a function of it and verify this function.

As for the method of addition you can use spin on techniques or you can use evaporation deposition technique in vacuum evaporators and printing. There are other methods you can find them in the literature.

i want to add nanoparticls like in this mesh

this will improve the efficiency of osc

Abdelhalim abdelnaby Zekry

thanks Xuhua Wang

yeah this is the structure of organic solar cell

i want to add nanoparticle to improve the efficiency of it

so what is the decbuild command to add nanoparticles inside layers like in this image

Dear dr Abdelhalim abdelnaby Zekry

thank you for your response

the description of material is the important , you are right

but i want to add different shapes of nanoparticles

and each shape will give different result

as nanoparticle improve the absorption of light so it will give different result if we change the shapes of it (size , distance between them)

so each shape will have different description of material and different result

i search (how to add nanoparticle in silvaco ) it give me result in silvaco website

as this is done by using victorymesh

but i have no information about it also the website not give information about it

but it give input file start with

go victorymesh and it give error at decbuild

Dear Mahmoud Fekry ,

Mahmoud,

Yes if your material is nonhomogeneous then you have to ways to describe the material:

Through the averaging of the parameters

or by the two dimensional profiles of the parameters as you want to realize!

thank you prof Abdelhalim abdelnaby Zekry
