Abstract
We present a theoretical model describing the photo-electrical response of a system composed of quantum dots embedded in a dielectric matrix. The model is based on the non-coherent rate equations and the Transfer Hamiltonian formalism. The self charge was included. Within this methodology, the response of the system only depends on fundamental material parameters and its geometry. Transport through several quantum dot configurations was simulated obtaining current-voltage curves in dark and illuminating conditions for three different scenarios: single one quantum dot and two quantum dots in parallel and serial configurations. Despite the simplicity of the model, it has been used to reproduce successfully experimental results.
