Spray coating technique has been established as a promising substitute for the traditional coating methods in the fabrication of organic devices in many reports recently. Control of film morphology at the microscopic scale is critical if spray-coated devices are to achieve high performance. Here we investigate electrospray deposition protocols for the fabrication of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) thin films with a single additive system under ambient conditions at room temperature. Critical deposition parameters including solution composition, applied voltage, and relative humidity are discussed systematically. Optimized process for preparing homogenous PEDOT:PSS thin films is applied to all-electrospray-coated organic photovoltaic cells and contributes to a power conversion efficiency comparable to that of the corresponding all-spin-coated device.

The thin films of poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] (MEH- PPV) used as photoactive layer in organic photovoltaic cells were prepared on glass substrates by the spin-coating technique. The transmittance spectra of thin films were measured by a double beam spectrophotometer. The optical constants such as refractive index and extinction coefficient of the thin films were determined from the measured transmittance spectra using the method of whole optical spectrum fitting. The complex dielectric constant and the complex optical conductivity of the thin films were obtained. In addition, the optical bandgap of the thin film were calculated according to the Tauc's law. The results show that the thin films exhibit direct allowed transitions and the optical bandgap is about 2.18 eV. These results provide some useful references for the design and optimization of device structure in organic photovoltaic cells.
