Embodiment Construction

[0132] In one embodiment of the invention, figure 1A schematic diagram of a component 1 embodied as an inorganic solar cell is shown, by way of example. The component 1 is arranged on a transparent substrate 2 which is preferably designed in a flexible manner, for example as a film. Arranged on top of this substrate 2 are electrodes 3 implemented from metals, conducting oxides (especially ITO, ZnO:Al or other TCOs) or conducting polymers (eg PEDOT:PSS or PANI). Arranged on top of this electrode 3 is a charge carrier transport layer 4 , eg implemented as an electron or hole transport layer. Arranged on top of this charge carrier transport layer 4 is a photosensitive layer 5 comprising at least one donor material and an acceptor material, which together form a donor-acceptor system. Furthermore, the photosensitive layer includes a third material having a proportion of 0.1% by weight<x<10% by weight. This third material is selected from the group consisting of crown ethers, t...

Abstract

The invention relates to an optoelectronic component comprising a photoactive layer which is arranged between an electrode and a counter electrode. In addition to a donor-acceptor system, the photoactive layer comprises a third material which influences the crystallization of the donor-acceptor system. The third material is selected from a group consisting of crown ethers, triphenyls, sorbitols, quinacridones and bis(4-(tert-butyl)benzoato-O) hydroxyaluminium. Crown ethers are especially preferred.

Description

technical field [0001] The invention relates to an optoelectronic component having a photosensitive layer arranged between an electrode and a counter electrode. Background technique [0002] Optoelectronic components, such as solar cells or LEDs, TFTs, etc., are now widely used in everyday life and in industrial fields. [0003] For example, there are known thin-film solar cells which have a flexible embodiment and thus allow arrangement on curved surfaces. This type of solar cell is preferably made of amorphous silicon (a-Si) or CIGS (Cu(In,Ga)(S,Se) 2 ) composed of the active layer. [0004] A particular disadvantage of these thin-film solar cells is the high production costs caused by the materials. [0005] Also known are solar cells with an organic active layer having a flexible embodiment (Konarka Konarka—Power Plastic Series). These organic active layers may be formed from polymers (eg US7825326B2) or small molecules (eg EP2385556A1). Whereas a feature of polymer...
