Poly(vinyl pyrrolidone): a superior and general additive in polysulfide electrolytes for high efficiency quantum dot sensitized solar cells

Abstract

Poly(vinyl pyrrolidone) (PVP) was used as a superior and general additive to modify the traditional polysulfide electrolyte in quantum dot sensitized solar cells and the photovoltaic performance of the constructed solar cells was significantly improved benefiting from the reduced charge recombination.
