Abstract
We investigate the possibility of modifying the porous structure of TiO2 films in dye-sensitized solar cells (DSSC) in its sintering by a pulsed Nd:YAG laser (wavelength 1064 nm) to improve their parameters and characteristics. Sintering at various pulse energies enabled a porosity within the range of 0.45 to 0.20. The efficiency of the energy conversion in experimental DSSC specimens with TiO2 films sintered by an optimum laser-radiation pulse energy of 150 mJ was 20–25% higher than that of commercial solar cells.
