I am trying to reproduce the photocurrent calculation from tutorial as given on the Quantum ATK website,
https://docs.quantumatk.com/tutorials/photocurrent/photocurrent.html
and in that turorial, while doping the silicon device, it is asked to have the doping of both p and n types in the left electrode only. And i am not able to understand why both the n type and p type dopings are said to be done in the left electrode. So clarify my doubt. attached with this post is a screenshot from the tutorial where the dopings are  done.

Yes, the picture is somewhat misleading.
The doping is applied to the left and right electrode respectively as written in the tutorial text.
Please also refer to the script silicon_pn_junction.py attached on the tutorial.
There doping is clearly applied to the left and right electrode regions.
