In present work the influence of anodizing process parameters on PAOT geometric parameters for optimizing and increasing ETA-cell efficiency was studied. During the calculations optimal geometrical parameters were obtained. Parameters such as anodizing current density, electrolyte composition and temperature, as well as the anodic oxidation process time were selected for this investigation. Using the optimized TiO2 photoelectrode layer with 3,6 μm porous layer thickness and pore diameter more than 80 nm the ETA-cell efficiency has been increased by 3 times comparing to not nanostructured TiO2 photoelectrode.
The features of the formation of multi-component metal sulfide films (Cu2ZnSnS4 and Cu2SnS3) formed by various methods SILAR technology were studied. Using different investigate methods the comparative analysis of the properties and composition of the films were carry out. The formation of a multi-component film in the mixed cationic solution is accompanied by additional processes in the solution and by the appearance of complex compounds. This factors has a strong influence on the composition and purity of the formed films. The characteristics of the solar cell test structures with ultrathin absorbing layer based on Cu2ZnSnS4 and Cu2SnS3 were obtained. It’s necessity to introduce an interlayer and make more carefully study of the composition and interface of the absorber layer.
