Why do we usually not consider the substrate in modelling of structures like HEMT or solar cells in SILVACO ATLAS simulation?

In many of the examples in SILVACO ATLAS, i find most of the structures are modeled without substrate. But i can see a lot of difference in the device performance with n without substrate. So...
