Reviewer 1 Report
This manuscript was written by Alaa A. Zaky et al. reports on the fabrication of the perovskite solar cells via nature-inspired search optimization algorithms. From my perspective, this manuscript contains information that can be of interest to the scientific community and recommend its publication. However, amendments must be made before the final publication. Below are listed my observations.
- Would you please provide the cross-sectional SEM image of PSC architecture in the revised manuscript?
- How does the present work gain novelty?
- How economical when it comes to production on an industrial level. Did the authors have any estimation?
- Authors need to re-check their manuscripts for spelling and grammatical errors.
- The authors need to remand the entire reference format. In addition, authors must re-check the manuscript for abbreviations, author names of journals.

Response: Thanks for your comment. Thanks for kind word and your comment. We did our best to enhance the work.
- Would you please provide the cross-sectional SEM image of PSC architecture in the revised manuscript?
Response: Thanks for your comment. The cross-sectional SEM image of PSC architecture has been added to the manuscript in Figure1c

- How does the present work gain novelty?
Response: Thanks for your comment. In this work, a proposed modified triple-diode model (MTDM) for perovskite solar cells (PSCs) modeling and simulation is used. The Bald Eagle Search (BES) algorithm which is a novel nature-inspired search optimizer is suggested for solving the model and estimating the PSCs device parameters because of the complexity nature of determining the model parameters.
For PSCs performance better understanding, parameters like diode ideality factors and diodes saturation currents values are very important and these parameters value are difficult to be determined experimentally. In the simulation models (TDM, MTDM) the diodes ideality factors and diodes saturation currents can easily determine which is a big merit of the simulation process which supporting the analysis and performance evaluation of the PSCs.

- How economical when it comes to production on an industrial level. Did the authors have any estimation?
Response: Thanks for your comment. In our group previous publication this point has been already discussed under this title:-
(Energy Efficiency Improvement of Water Pumping System Using Synchronous Reluctance Motor Fed by Perovskite Solar Cells) which is reference 34 in the manuscript.

The following paragraph was added to the manuscript from Line 250 to line 255.
A techno-economic study for the third generation perovskite solar cells in real water pumping system application for irrigation purpose was carried out in [34] proving the superiority of the PSCs in comparison with the silicon based technology solar cells where for the same application the PSCs based case there is a cost saving and needs only 3.42 m2, as installation area which is very small in comparison with the corresponding area of conventional silicon based solar cells that exceeds 36 m2.
- Authors need to re-check their manuscripts for spelling and grammatical errors.
Response: Thanks for your comment. The authors need to remand the entire reference format. In addition, authors must re-check the manuscript for abbreviations, author names of journals.

Reviewer 2 Report
The authors discussed the results of inserting porphyrin over the conventional ETL and evaluated the performance of PSCs. Electrical modeling was used to validate the results.
The manuscript needs some minor changes to the text to address a few typos around significant figures in the text.
Detailed comments:
The authors used modified triple-diode model to describe perovskite solar cells. Bald eagle search algorithm was used to model the solar cells and its results were compared against other methods for accuracy in determining parameters of the modified triple-diode model. The work highlights the importance of modeling in understanding the properties of PSCs and further validates the accuracy with the incorporation of pyrophyrin. The work is relevant to the perovskite solar research community and adds to the existing literature on triple-diode models.
1. Figure 13 and 14 describe the absolute current density error for TDM and MTDM, however its unclear what the sub figures 13a, 13b and 14a, 14b are about.
2. It is also recommended to elaborate more on the Figure 15 and describe what each sub figure is explaining in detail.
3. Additional experimental data regarding open-circuit voltage and Fill factor will help understand the effect of pyrophyrin on the performance of PSCs.
4. Several typos exist in the manuscript and would need a thorough review by a native English speaker to improve the general quality of the manuscript.

Response: Thanks for your kind words and the summary of the work
- Figure 13 and 14 describe the absolute current density error for TDM and MTDM, however its unclear what the sub figures 13a, 13b and 14a, 14b are about.
Response: Thanks for your comment. In this study two groups of PSCs devices were used namely the control device and the modified device which contains pyrophyrin. The sub figures 13a, 13b are for the absolute current density error for TDM for the control device and the modified device respectively while the sub figures 14a, 14b are about the absolute current density error for MTDM for the control device and the modified device respectively. The sub figures 13b and 14b titles have been updated in the revised manuscript.
We highlighted theses captions in the revised version
- It is also recommended to elaborate more on the Figure 15 and describe what each sub figure is explaining in detail.
Response: Thanks for your comment. We considered this point on the revised version.
- Additional experimental data regarding open-circuit voltage and Fill factor will help understand the effect of pyrophyrin on the performanceof PSCs.
Response: Thanks for your comment. This paragraph was added to revised manuscript (lines 242-249)
The PCE enhancement for the modified devices was associated with the increase of Jsc and FF parameters, while the Voc value was almost the same (~1.04 V). Specifically, the best performing modified PSC provided a short circuit current density of 23.52 mA cm−2, which was 4% larger than that of the reference one. The observed increase was assigned to the presence of the porphyrin’s negative dipole moment at the interface, which facilitated the electrons transfer to the photoanode. An additional improvement was registered in the case of fill factor, where the modified device presented a higher FF value (0.75) compared to the reference one (0.71).
- Several typos exist in the manuscript and would need a thorough review by a native English speaker to improve the general quality of the manuscript.
Response: Thanks for your comment. The manuscript has been reviewed and updated
