Abstract
Provided are organic n-doped electron transport layers comprising at least one electron transport material and at least one electron rich dopant material and organic p-doped hole transport layers comprising at least one hole transport material and at least one electron deficient dopant material.
Claims23
An organic n-doped electron transport layer comprising at least one electron transport material and at least one electron rich dopant material.
An organic p-doped hole transport layer comprising at least one hole transport material and at least one electron deficient dopant material.
The device of claim 17 wherein the photoactive layer is directly on the hole transport layer and the electron transport layer is directly on the photoactive layer.
A method of making a layer comprising:
- providing a solution comprising either a hole transport material and a p-dopant in an organic solvent or an electron transport material and an n-dopant in an organic solvent;
- applying the solution to a substrate;
- and
- removing at least a portion of the solvent.
