How I create a complete Multiphysics model on COMSOL for an Optoelectronic device like thin film solar cell or photodiode, I need more details about model and How can I plot the different figures
Hi Khalil,
I am assuming that you are new to Comsol. If that is the case, I would suggest that the best place to start is a suitable tutorial example. Comsol provides several examples that are a good place to learn the details of what goes into a typical multiphysics model of a particular device.
Here is a model of a photodiode (https://www.comsol.com/model/gaas-pin-photodiode-19705) and here is one of a solar cell (https://www.comsol.com/model/si-solar-cell-1d-35661).
You can download the files (which includes the model) and go through the accompanying tutorial which lists the steps involved in building the model. If you feel that this is the device that you are looking for then you can easily tweak the parameters of the example to suit your needs. Even if you are looking for something that is quite different from the example, going through the steps will give you a fairly comprehensive overview of the capabilities of the tool and you will learn how to setup and run a simulation and how to plot graphs.
I hope this helps and let me know if you have any further questions.
Regards,
Arjun
The lib. files to do the models of solar cell and photo diode are already exists in COMSOL multi physics tools, if you want to change the dimensions as well as materials, you may do that based on their properties..

First, you can start with the tutorials in the comsol to learn how to build geometry and add physics .......
Second, you can enter to the application library and choose example near to your model

I have some questions about the simulation of the surface recombination in the semiconductor model in Comsol.When I use the ideal ohmic contact, I can't set surface recombination, but when I use the schottky contacts, it's hard to get the result. So, how can I set the surface recombination?
Zhou Sihong : Sorry for the delay. I understand that Comsol has the ability to model surface recombination but you are unable to set it for the boundary condition (ohmic or Schottky) of your choice. Could you elaborate on what your structure is and what problem you are facing? What do you mean by hard to get the result?
Meanwhile, are either of these examples similiar to what you are you trying to accomplish?
