Absorption spectra (a), photoluminescence spectra (λexc = 450 nm) (b), and TEM image (c). Absorption spectra of the pristine P3HT, CIGS NCs, and P3HT:/CIGS NCs layer (a), photoluminescence spectra (λexc=450nm) of P3HT in composites, consisting of different concentration ratios between CIGS NCs and P3HT (b), and TEM image of the CIGS NCs dispersed in P3HT matrix with the weight ratio of 60 wt.% (c).
