Dear Ashraful

The bandlab package LmtArt can draw the energy valence bands

downloadable from this link http://www2.fkf.mpg.de/andersen/docs/lmtoart_programs.html

examples on this link

Try this

In Microsoft work. you can easily draw your energy band diagram with few minute. Follow step: open Microsoft Word..go insert window...shapes.. New Drawing canvas.

Good luck

Great Question with useful answers.

Very useful answers. Thank you!

The best software yet is OriginLab pro. You need to enter your data and take the transpose of it, and then plot the data using line type. You may then need to do some manipulations and then you will get something like the plot below.

Try SCAPS or AFORS-HET, they are free and can simulate the energy band in a solar cell.

You can use nextnano for a better understanding. But unfortunately it is paid.
