FIG. 2.

(Color online) Absorbance and PL spectra of pristine P3HT and P3HT:PbSSe NC (1:1) hybrid blend separately dispersed in chlorobenzene in (a) UV-vis and (b) NIR regions.

FIG. 3.

(Color online) (a) EQE spectra of the two types of SCs with pure P3HT and P3HT:PbSSe NC (1:1) nanocomposites, and the expected carrier flows in the device consisting of ITO/PEDOT:PSS/P3HT:PbSSe NCs/LiF/Al; (b) J–V characteristics of the devices in the dark and under AM 1.5 illumination. The inset shows three J–V curves indicating the lowest, highest, and average performances from the 1:1 hybrid device.

FIG. 4.

(Color online) JSC and PCE of SCs made of different ratios of photovoltaic materials in the hybrid compound under AM 1.5 illumination: P3HT:PbSSe NC weight ratios of 1:0, 1:0.5, 1:1, 1:1.5, 1:2, 1:3, and 1:4 (20 mg/l). The error bars indicate the variance among six results from nine devices.
