Embodiment

[0146] In the following exemplary embodiments, the functional applicability of the compounds proposed according to the invention is shown by the example of ellagic acid.

[0147] figure 1 The results of grazing incidence X-ray diffraction (GIXRD) of a 5 nm thick polyphenol-containing layer are shown. The layers were vacuum deposited on SiO wafers coated with 10 nm C60. figure 1 The layers used as templates are deposited onto room temperature substrates. The three Bragg (Bragg) reflections at 2θ of 10.9°, 18.2° and 20.7° are assigned to the face-centered cubic (fcc) phase of the C60 sublayer [Elschner, C. et al.: Determination of C60 molecules in thin films with the aid of X-ray diffraction Arrangement, Journal of Applied Crystallography, 44(5):983-990, 2011 (Elschner,C.et al.: Determining the C60 molecular arrangement in thin films by means of X-ray diffraction.Journal of Applied Crystallography,44(5) :983-990, 2011)].

[0148] The reflection at 27.6° is assigned to the te...

Abstract

The invention describes the use of polyphenols and polyamino derivatives adjacent to absorber layers on the basis of small molecules in organic optoelectronic components.

Description

technical field [0001] The present invention describes optoelectronic components, in particular organic optoelectronic components, having polyphenol and polyamino derivatives. Background technique [0002] Organic optoelectronic components enable the conversion of light into electricity using the photovoltaic effect, for example as solar cells. For the organic semiconducting materials required for the conversion to have sufficiently good absorption properties. These absorber materials are preferably small organic molecules, the optical and electronic properties of which depend strongly on the orientation of said organic molecules. [0003] In order to fabricate efficient organic photosensitive devices, they usually consist of multiple stacked cells between two electrodes in a series or multilayer structure, where the photosensitive layer (i.e. the cell layer) can also consist of multiple layers, the photosensitive layer Absorbs light and helps generate electricity. The or...
