Figure 1: PbSe nanocrystal absorption spectra.
From: In situ measurement of exciton energy in hybrid singlet-fission solar cells
Absorption spectra of the lead selenide (PbSe) semiconductor nanocrystals used during this study, in solution. The nanocrystals range in monodispersity from 3–6%. Curves are labelled with the nanocrystal bandgap in the film.
