Resumo:	The exciton energy transfer in organic bilayer structures, consisting of donor and acceptor layers with volumetric and random dipole distribution, was investigated as a function of their separation distance. This complex system was analyzed using a simplified quantum efficiency model based on the integrating sphere method that enabled us to determine the dominant interaction mechanism, whose geometry for energy transfer considerably differs from a point-to-point dipole interaction. In addition, the proposed model can also be applied to retrieve the average interaction distance between donor and acceptor chromophores for systems with well known geometries.
