Abstract: The present invention is directed to a process for preparing a hole transport layer in which a hole transport composition comprising a blend of a hole transport material and transition metal oxide or metal sulfide nanoparticles is deposited as a solution onto a substrate, such as an anode, and then is annealed in a subsequent step. It has been discovered that annealing the hole transport layer comprising the blend of an hole transport material and transition metal nanoparticles improves hole mobility of the hole transport layer in comparison to an identical hole transport layer that has not been subjected to an annealing step.
