Fabrication of non-fullerene P3HT/Agx-TiO2 based polymer solar cells with high open circuit voltage

This paper describes the effect of localized surface plasmon resonance (LSPR) in the non-fullerene bulk heterojunction polymer solar cells (BHJ PSCs) by incorporating Ag x -TiO 2 null nanocomposites into the active layer. Four types of Ag x -TiO 2 null nanocomposites with different contents of Ag and distinctly different crystallite size and great uniformity were synthesized to systematically probe their influences on photovoltaic performances...
