The evolution of charged defects in poly - crystalline solar
cells leads to a large system of reaction diffusion equations
exhibiting largely different time and spatial scales. The
basic structure of the system is quite general, and equivalent to a kinetic system given on a general network.
The same structure arises in many applications such as biological systems with many species.
We discuss
asymptotically preserving computational methods based on
an operator splitting approach.
