| 20120126213 | Semiconducting Component - The present invention relates to an organic semiconductor element that comprises multiple layers. One or more layers may include compounds that can function as light absorbers, charge transporting materials, and/or as a dopant. | 05-24-2012 |
| 20120125419 | PHOTOACTIVE COMPONENT COMPRISING AN INVERTED LAYER SEQUENCE, AND METHOD FOR THE PRODUCTION OF SAID COMPONENT - A photoactive component comprising organic layers, in particular a solar cell comprising a photoactive i-layer system, contains at least one mixed layer. The mixed layer contains at least one donator material and one acceptor material, and thus forms a donator-acceptor system. The donator material and the acceptor material of the mixed layer are non-polymer materials. In a vacuum, the donator material has an evaporation temperature which is at least 150° C. lower than the evaporation temperature of the acceptor material and has an inverted layer sequence with an n-i-p, i-p, or n-i structure of an n-layer, i-layer, or p-layer system respectively. The organic photoactive i-layer system is applied directly onto the cathode or onto an electron-conducting n-material system. | 05-24-2012 |
| 20090217980 | Organic Photoactive Device - 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′) that are each connected to a donor unit (D), and conjugated donor-acceptor-donor oligomer (D-A-D′ oligomer) with a donor unit (D) and a further donor unit (D′) that are each connected to an acceptor unit (A). | 09-03-2009 |
