A cell, comprising:
- a substrate,
- first electrode,
- a photovoltaically active layer comprising an organic material, and
- a second electrode made of a predominantly organic material,
- wherein:
- the first electrode is between the substrate and the photovoltaically active layer and has a first work function,
- the photovoltaically active layer is between the first and second electrodes,
- the second electrode is opaque and has a second work function higher than the first work function, and
- the cell is a photovoltaic cell.
A method for producing a photovoltaic component, wherein applied to a substrate is a first electrode having a first work function, thereon a semiconductive, photovoltaically active functional layer comprising an organic material, a second electrode comprising a predominantly organic material is applied to the semiconductive, photoactive functional layer to provide the photovoltaic component, wherein
- the second electrode is opaque and has a second work function higher than the first work function.
A component, comprising:
- a substrate;
- a first electrode that is semitransparent;
- a second electrode comprising a predominantly organic material, the organic material comprising PEDOT;
- and
- a photovoltaically active layer between the first and second electrodes, the photovoltaically active layer comprising an organic material
- wherein the first electrode is between the substrate and the photovoltaically active layer and has a first work function, the second electrode is opaque and has a second work function higher than the first work function, the component is a photovoltaic component.
An article, comprising:
- a substrate,
- a first electrode,
- a photovoltaically active layer comprising an organic material, and
