To consider this paper (Manuscript reference: PHYSSCR-134652) for acceptance in the journal, it is essential to address the following major areas that require significant revision:
1. The paper title should be clearer and easier to understand.
2. I noticed that certain abbreviations, such as ETL, HTL, PCE, Voc, and PSC, are repeatedly introduced in their full form throughout the manuscript. Typically, an abbreviation should be defined only once at its first mention and then used consistently in its abbreviated form. Adhering to this standard will improve readability and maintain a smooth flow for readers.
3. The novelty section should be expanded to clearly articulate its key contributions. Additionally, this section should be placed as a distinct paragraph at the end of the introduction to enhance coherence and flow, without merging it with other paragraphs.
4. Figures 1 and 2 should have clearer titles, as the current titles may cause confusion.
5. In the table 3, please clarify the meanings of the abbreviations "r" in "rGO," "Al" in "Al-ZnO," and "Li" in "LiTiO2." If these terms are essential, they should be clearly defined for better understanding.
6. On page 8, line 47, you mention "700 nm" but then refer to "micrometer." It is recommended to consistently use "nanometer" throughout the manuscript. Please review line 56 on page 8 and the relevant sections on page 9, as well as the entire manuscript for consistency.
7. The author should provide a clear explanation for the inconsistent use of "nanometer" and "micrometer" throughout the manuscript. Clarifying the rationale behind this choice will enhance understanding.
8. You have cited many older references in the manuscript. I suggest incorporating more recent literature to provide a contemporary perspective. Consider including studies such as:

• Numerical investigation and design optimization for enhanced efficiency of Cs2AgBiBr6perovskite solar cell, Phys.Scr. 99(2024)105110. https://doi.org/10.1088/1402-4896/ad7545

• Design and numerical investigation of Cs2SnI6 vacancy-ordered double perovskite solar cell, Optics & Laser Technology Volume 181, Part B, February 2025, 111820 , https://doi.org/10.1016/j.optlastec.2024.111820

1. Figures 5, 6, 10, and 11 require higher quality for better clarity and presentation. Please review and improve the resolution of these figures.
2. The level of English language used in the manuscript is moderate and needs improvement to meet academic standards. Please revise the entire manuscript sentence by sentence for clarity and coherence.

The author has carefully made all the revisions and has described everything clearly.
