Photophysical properties of poly (3–hexylthiophene) on the islet silver films

Abstract

Influence of surface plasmon resonance of the islet silver films on the transformation of light energy in polymer films of poly (3–hexylthiophene) has been studied. It is established that the increase in the intensity of absorption and fluorescence of films of the polymer Р3НТ about four times on the surface of the islet silver films. The observed dependence was associated with the change in the rate of electronic transitions in macromolecules of the polymer under the action of the local electromagnetic fields near the surface of silver nanoparticles. Study of the effect of plasmonic silver nanoparticles on the photovoltaic parameters of organic solar cells based on bulk hetero junction was performed. The increase of the photovoltaic parameters of the cell by 1.6 times during the registration volt-ampere characteristic of solar cells on the effect of the plasmon resonance was recorded.
