ldwillia / sl3me Goto Github PK

I was recently contacted by @luqmansaleem99 to help him with calculating the SLME. He seems to have since found this repository and already raised an issue.

It's been a while, but looking back, I seem to have forked and made quite substantial changes to the code base some 5 years ago, when I was working on the topic with Kamal Choudary (not sure what his GitHub username is) on our paper:

https://github.com/mbercx/SL3ME

I never integrated these changes into the main repository though. 😅 @ldwillia if you're ok with it, I'll clean up the code some more (can't work on this too much I'm afraid) and open a PR.

On the topic of the issue I'm raising: I'm wondering if perhaps we shouldn't rename the repository to slme? It should still be easy to find, capital letters are kind of a no-no in my book, and then we can also just grab slme on the PyPI (it doesn't seem taken) and make the package installable with pip.

I consider that this is the SLME method to calculate efficiency of solar cells. This code needs fundamental and direct allowed band gaps along with the absorption coefficient in m^-1 units. I am providing it all the data and this code gives me the standard SLME's value -3e-11. I don't how to interpret this number -3e-11. What exactly is it? I was expecting that I will get some number like 0.20 (for 20% efficiency). But the number is so small, -3e-11.

Can someone please clarify my confusion?

I could run it for Wien2k data.
I have prepared a file optical (absorption) data and name the file as mock_CdTe_mat_abs.dat and kept that attached am1.5G.dat in the same folder. I used data in the mock_CdTe_mat_abs.dat file into meter inverse.
Then I updated the bandgap in these two lines.

material_direct_allowed_gap = 1.797 #
material_indirect_gap = 1.797 #

and then executed it as
python SL3ME.py.

Could you please confirm whether I am executing it in the right way or I am missing something?

It's better to provide a small non-zero value for x0 (say 0.0001) instead of exact zero, else the code gets stuck for many materials.

hi
i am brand new to python. I would like to use this script in my work.
It would be possible to make a small tutorial on how to use this script.
thank you very much
