I would like to modify the default equations in the semiconductor module

I am planning to modify the default drift-diffusion equations under the Semiconductor Material Model. Also, I would like to add a new equation related to exciton concentration into the simulation.
Here are the equation I want to modify.
I read some of the post in the forum, and they said that I could modify the equations in the equation views panel. I have tried to understand the variables and weak formula in the equation view but I found that it was very complex. I want to find the weak expression or variables related to this equation, but I cannot find the ones correspond to this equation. Could anyone give me some hints how to modify the equation?
Also, I want to add a new equation related to the concentration of exciton. The equation is very similar to the drift-diffusion equation of electrons and holes. Is it possible for me to add some equation similar to the default drift-diffusion equation by using the PDE interface and couple it with the semiconductor module?
