PbS1−xSex-Quantum-Dot@MWCNT/P3HT Nanocomposites with Tunable Photoelectric Conversion Performance
Round 1
Reviewer 1 Report
The manuscript by Zhu et. al. represents the tunable photoelectric conversion properties of QD-embedded nanocomposites. The paper is written very clearly and claims are supported by the appropriate experimental data. I would like to recommend to publish in its present form. after clarification of following comments which authors should look into for the improvement of the manuscript :
(1) Size of QDs from TEM data as hitogrammed in the supplementary should be fitted. Also, the bin widths are not same for all the histogram plots.
(2) In Fig. 1(f), XRD peaks are shifted to the lower angle with higher X values. Can authors explain this in the manuscript?
(3) In Fig. 3(d), which excitation wavelength is used to the fluorescence decay measurements? I would also like to plot the decay curve as semi-log plot i.e. plot y-axis in log scale and x-axis as it is.
(4) Is there any specific reason to measure photocurrent at 480 s with different x-values? The maxima for x = 0.25, is it remain same with if one measure at different time (lets say 360 s, 600 s etc.)?

Reviewer 2 Report
Dear Editor, thank you for the trust and the opportunity to provide a review of the work "PbS1xSex-Quantum-Dot@MWCNT/P3HT Nanocomposites with Tunable Photoelectric Conversion Performance" He Zhu, Huilin Hu, Minheng Ye, Jinhua Ye, Defa Wang.
The paper report about a nanocomposite light absorber based on PbS1xSex quantum dots, electron-conducting multi-walled carbon nanotubes and hole-conducting poly-3-hexylthiophene. Engineering of the band gap by solid solution PbS1xSex QDs (x = 0, 0.25, 0.5, 0.75, 1) was proposed. It should be noted what obtained nanocomposite can be used for the development of high efficiency photoelectric conversion devices.
The manuscript is well structured, nicely written and I consider it is suitable for the publication in present form.
