Round 1
Reviewer 1 Report
The subject of the manuscript is attractive and the represented data are applicable for the researchers working on renewable energy systems. Following revisions are essential for the improvement of the manuscript and making it appropriate for publication is Sustainability: 1. Abstract section can be significantly modified by adding more key findings of the reviewed studies. 2. Some of the keywords can be replaced with more meaningful items. 3. Permission is needed for the reprinted figures. 4. Importance of PV/T system development must be indicated. 5. It would be useful to extend the literature review on the PV/T system integrated with other renewable systems. 6. Adding some data on the economic aspects of PV/T systems would be useful. 7. Adding more informative figures is suggested. 8. More references from Sustainability can be added. 9. Writing needs recheck and enhancement.Author Response

Reviewer 2 Report
Dear Authors,
In your manuscript, a review of PV/T systems exergy analysis is provided.
The review provides a comprehensive review of such analysis. It might be helpful to provide some expressions for different types of exergy calculations before providing the results of different sources with PV/T exergy analysis.
There should not be abbreviations used (or at least without the full meaning of it) in the title and keywords. Hence, adding at least the full meaning of PV/T in the title and keywords is recommended, too.
Check for the language errors (Page 1 Line 23 "Extracted heat", P1L24 "This article review ... and discussed...", P1L25 "Based in the findings", P1L28 "may prompt improvement", P31L31 "for the next works", P1L35 "the two", P4L129 "length to with", P6L203 "Remarkably", use of inappropriate terminology - e.g. "rise" instead of "increase", not always correct use of the articles ("a" and "the"), etc.). It is recommended to provide the manuscript to a native English speaker to correct the language used.
Write the subscripts where it is appropriate (e.g. in the case of Al2O3, TiO2, Fe3O4, etc.).
It is strange not to find a single citation from this journal. Maybe it is not a good fit for this topic.
No unified style of reference writing (check ref. [42]).
P10L331 is missing the reference ("Error! Reference source not found").
Correct the typographical errors (e.g. P10L31-32 "s ystems").
Excessive bullet (P12L359 - beginning of the Conclusion section).

Paper title: PV/T as Promising Technologies in Buildings: :a Comprehensive Review on Exergy Analysis
Subject: sustainability-1854995 peer-review report
Date: 08.08.2022
A brief summary
The paper presents an analysis of techniques to keep solar photovoltaic (PV) systems at low temperatures for optimal efficiency.
In practice various thermal management techniques, involving the cooling of solar cell have been introduced to keep the temperature low. It has been shown that, the extracted heat in these systems, known as PV/T, can be applied for some purposes including water or air heating. This article reviews the works on the PV/T systems exergy analysis and discussed their findings. Based in the findings of the reviewed works, different factors like the system configuration, used components and elements and working conditions affect the exergy efficiency of these systems. Moreover, usage of some components like glazing can lead to avoidance from thermal energy loss that would be beneficial from exergy point of view.
The paper is based on a properly conducted literature analysis. 71 items of contemporary world literature were used.
The overall quality of the manuscript is good. The manuscript contains good-quality contents and results. The results of the analysis can be used by designers and operators of solar photovoltaic systems
The topic of the manuscript is also interest to the readers of sustainability.
However, the submission contains several technical and editorial drawbacks, which according to my humble opinion, require slightly revision before the submitted manuscript can be considered as publishable. Some comments are given next.
Broad comments
Introduction - the information contained introduces the content of the paper well.. Should be expanded on the purpose of the analysis carried out in the paper.
PV/T systems in buildings - without remarks
Exergy analysis of PV/T systems - analysis carried out correctly. Noteworthy is the consideration of different types of heat-trapping fluids
Suggestions for Future Researches and Conclusion - chapters too small. The results of the analysis make it possible to expand and refine the guidelines for further research and conclusions
Specific comments
Figure 5. - it is useful to explain the abbreviations shown in the figure (S, U, V and etc.).
Line 331 - Clarify the meaning of the sentence or delete it.
