Abstract
With aim to increase set of modern commercial optoelectronic devices we investigate the optical properties of new triple semiconductor-organics-semiconductor nanostructure having two semiconductor layers with organic layer between. This will be development to majority of modern publications with investigations of only double hybrid nanostructures with one contacting semiconductor layer and one organic layer. It is supposed that the energy of exciton in the first layer is larger than the energy of exciton in organic layer and that the energy of exciton in organic layer is larger in comparison with energy of exciton in second semiconductor layer. It was shown that installation of organics leads to some frequencies at different parameters or to reflection increasing and transmission decrease or to reverted dependence. New recurrent method of inverted calculation for fields is proposed and using this method the frequency dependences of optical characteristics have been calculated. The role of second semiconductor layer in considered triple structure has been estimated.
Highlights
The majority of modern commercial optoelectronic devices such as LEDs, solar cells, and nonlinear-optical devices are built mainly on the basis of traditional inorganic semiconductors

Summary
The majority of modern commercial optoelectronic devices such as LEDs, solar cells, and nonlinear-optical devices are built mainly on the basis of traditional inorganic semiconductors. Such approach was widely investigated and the results can be found in many review papers [2]-[11]. We assume that external orthogonal to surfaces optical irradiation produces in the first semiconductor layer the Wannier-Mott excitons with the rather high energy These excitons can create Frenkel excitons in the intermediate organic region of triple structure and we assume that their energy will be not less than the energy of the Wannier-Mott excitons in the last and lowest third layer of hybrid structure. The influence of organic layer on the frequency of reflection and transmission is discussed and the comparison of spectra without and with installed organics defines region of frequencies where organic layer gives positive effect
