Reviewer 2 Report
Thermophotovoltaics (TPVs), a heat recovery technique, is faced with low efficiency and power density. It has been proven that graphene helps add new functionalities to optical components and improve their performance for heat transfer. In this work, I study Near-field radiative heat transfer in TPVs based on a composite nanostructure composed of Indium Tin Oxide (ITO) sheet and a narrow bandgap photovoltaic cell Indium Arsenide (InAs). I introduce a new way to calculate nonradiative recombination (NR) and compare the performance of whether the NR is considered. By comparing graphene modulated on the emitter (G-E), on the receiver (G-R), and on both the emitter and the receiver (G-ER), I find the G-ER case can achieve highest current density. However, constrained by the bandgap energy of the cell, this case is far less than the G-E case when 16
it comes to efficiency. By applying Variant Particle Swarm Optimization (VPSO) and dynamic optimization, the model is optimized up to 43.63 % efficiency and 11 W/cm2
electric power at 10 nm vacuum gap with a temperature difference of 600 K.
the manuscript will be accepted if following questions are addressed:
There are good articles in the introduction section, but it is better to mention different fields to make it interesting for the reader.

In the Schematic diagram of the NFTPV system, explain more about the heat sink and the effect on the mechanism.
Figure 3 and Figure 2 should be merged into one figure and explained more briefly.
Describe Figure 4a separately in the form of a separate figure in the text.
Where is the conclusion of the text?
