Abstract
In this paper, we study the nature and evolution of edge dissipativeless currents caused by the presence of topological Frenkel excitons in metal phthalocyanines (MPc) in the constant magnetic field, orthogonal to the plane of MPc molecule. We briefly review and analyze the 2D and 3D lattice tight-binding models with exciton currents for applications in the photovoltaic and spintronic devices. We give illustrative numerical simulations with the three dimensional lattice Monte-Carlo model.
Keywords: metal phthalocyanines, Frenkel excitons, lattice Monte-Carlo method
