An optoelectronic component on a substrate includes a first and a second electrode. The first electrode is arranged on the substrate and the second electrode forms a counter electrode. At least one photoactive layer system is arranged between these electrodes. The at least one photoactive layer system including at least one donor-acceptor system having organic materials.

Transparent electrode for optoelectronic components

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

Optoelectronic component

The description relates to an organic photoactive component, in particular an organic solar cell, having an electrode on the substrate and a top counter-electrode and a doped transport layer between the electrodes and a photoactive layer system, characterized in that a metal oxide layer is present between the photoactive system and the top counter-electrode.

Photoactive component having organic layers

A photoactive component has an electrode and an opposing electrode. The electrodes have at least one organic layer system arranged between them, also having at least two photoactive layer systems and, between the photoactive layer systems, at least two different transport layer systems have the same charge carrier type. In this case, one transport layer system matches one of the two photoactive layer systems in energy terms, while the other transport layer system is of transparent design.

Photoactive component having a plurality of transport layer systems

A photoactive component includes organic layers, including a single, tandem or multiple cell with two electrodes and, between the electrodes, a photoactive acceptor-donor layer system that includes at least three absorber materials. At least two absorber materials are donors or acceptors. One of the two absorber materials is configured as donors or acceptors absorbing at greater wavelengths than the other absorber material and one of the two absorber materials have a lower Stokes shift and/or a lower absorption width than the other absorber material.

Photoactive component comprising organic layers

The invention relates to an organic photoactive device, especially an organic photovoltaic cell, with a contact and a countercontact as well as with an organic region that is electrically connected to the contact and the countercontact, wherein a photoactive region with a photoactive bulk heterojunction or a flat heterojunction between an electron-conducting organic material and a hole-conducting organic material is formed in the organic region and wherein the hole-conducting organic material and/or the electron-conducting organic material is formed from oligomers according to any one of the following types: conjugated acceptor-donor-acceptor oligomer (A-D-A' oligomer) with an acceptor unit (A) and a further acceptor unit (A&#x2032;) that are each connected to a donor unit (D), and conjugated donor-acceptor-donor oligomer (D-A-D&#x2032; oligomer) with a donor unit (D) and a further donor unit (D&#x2032;) that are each connected to an acceptor unit (A).
