Spray deposition is emerging as an attractive low-cost and high throughput method for organic solar cell (OSC) fabrication. In this letter, we demonstrate that a highly conductive formulation of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) can be spray deposited to form the top electrode for an OSC. An inverted solar cell fabricated in this way with a blend of poly(3-hexylthiophene) and [6,6]-phenyl- C61 butyric acid methyl ester as the active layer achieved a power conversion efficiency of 2.0% under AM 1.5 100 mW/ cm2 illumination.
