A novel solution-based ultrasonic mist deposition method has been developed for the formation of organic solar cells. This technique enabled low-resistive gallium-doped zinc oxide (ZnO : Ga) and indium-tin-oxide (ITO) thin films capable of applying as anode layers in the device. Low resistive and flat PEDOS : PSS hole transport layer and P3HT : PCBM active layers were also deposited by this technique. The solar-cell devices with mist-deposited PEDOT : PSS or P3HT : PCBM layers showed higher short circuit current density and power conversion efficiency than those with spin-coated PEDOT : PSS or P3HT : PCBM layers. The results encourage the promising potential of the ultrasonic mist deposition method for low-cost device fabrication.
