Abstract Scope |
The purpose of the work is the manufactured the DSSC based on photoanodes in form of nanoparticles and nanowires combination. That structures leads to obtain large surface, improvements in electron transport efficiency and low electron recombination rate. The article describes the method of producing 1D nanostructures and the photoanode itself. The applied methods of electrospinning and screen printing, respectively, allow to achieve structural and dimensional homogeneity of the produced materials. Structural studies were carried out using atomic force microscope (AFM), RMS Ra roughness coefficients were determination to quantify of surface of the electrodes. Qualitative studies of chemical composition were conducted using Energy Dispersive Spectrometer (EDS). Optical properties were investigated in the wavelength range 200 to 900 nm using the UV-Vis spectrometer. The electrical properties of the manufactured test DSSCs were determined on the basis of the analysis of the I-V characteristics. Obtained cell efficiency results was in range 4.5–5%. |
