FIG. 3.

(Color online) Current density–voltage characteristics demonstrating the superior performance of the photovoltaic device incorporating pentacene (triangles) as compared to the one without pentacene (circles) under AM 1.5 white light with an intensity of . Inset: Typical infrared photocurrent response of the devices (with and without pentacene) when illuminated with white light passed through a long pass filter.

FIG. 4.

(Color online) Energy band diagram of the components of the hybrid nanocomposite photovoltaic device. The schematic also depicts possible paths of photogenerated charge carriers in the case of exciton formation in the PbSe QDs. The extra potential barrier originating from insulating ligand is also pictorially depicted.
