Abstract

We report on a sol-gel-based technique to fabricate MoO 3 thin films as a hole-injection layer for solution-processed or thermally evaporated organic solar cells. The solution-processed MoO 3 (sMoO 3) films are demonstrated to have equal performance to hole-injection layers composed of either PEDOT:PSS or thermally evaporated MoO 3 (eMoO 3), and the annealing temperature at which the sol-gel layer begins to work is consistent with the thermodynamic analysis of the process. Finally, the shelf lifetime of devices made with the sMoO 3 is similar to equivalent devices prepared with a eMoO 3 hole-injection layer.
