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.
