Recent Progress on Boosting the Perovskite Film Quality of All-Inorganic Perovskite Solar Cells

Round 1

Reviewer 1 Report

I haven’t seen any figure or table in this manuscript. I request the authors include a table of comparative efficiency data with process conditions.

Write a paragraph on why all-inorganic solar cells are better than organic-inorganic perovskite solar cells.

Please add important figures from the published articles and cite accordingly.

Author Response

Thank you for your valuable suggestions. We added some figures and tables to our manuscript. We also added a paragraph on why all-inorganic solar cells are better than organic-inorganic perovskite solar cells in the “Introduction”. They had been highlighted in red color.

Reviewer 2 Report

1-Compared the PL spectra from these systems.

2-Cpmared the variation in optical properties of such systems.

Author Response

Thank you for your valuable suggestions. The focus of our article was on how to prepare excellent inorganic perovskite films to improve the performance of PSCs. We added some tables to summarize the performance of the relevant PSCs. The PL spectra of PSCs were incomplete in the reported literature and difficult to summarize and compare.

Reviewer 3 Report

The article by Chen et al. attempts to provide a review on some methods to improve the thin film quality for a high PCE in recent years, such as additive engineering, solvent engineering, and interface engineering. Similar and rather detailed articles such as DOI: 10.1039/C9TA06674H, DOI: 10.3390/nano12101651 and many others have already been published and in current year (2022). Therefore, I do not think this article is worth publishing especially given that no new insights have been provided in comparison to the recently published reviews. In addition, some comments below can be utilised by the authors and rather make this current view very amateurish

 

Some further clarifications needed on how? Pg 1 line 30-32. “.The replacement of organic components in perovskite materials with inorganic materials can largely avoid the influence of the external environment, thereby effectively improving the PCE and stability of PSCs “.  The authors should explain how?

 

The works fails to explain to the reader how additive engineering, solvent engineering, and interface engineering are utilised to improve PCE of inorganic cells. The article mainly tells the reader the “what” and ignores the “how” and “why”

 

No in-depth conclusions have been provided which could inform the reader of the limitations of the several approaches and how improvements can be driven. Which are the possible changes? Etc

 

 

 

Author Response

Thank you for your valuable suggestions. Please forgive us for writing this review for the first time. We added some related literature, including your mentioned. We added a paragraph to explain the advantages of all-inorganic PSCs in the “Introduction”. We tried to explain “how” and “why” after the related literature. We analyzed and classified the references, adjusted the order, and made our thoughts clearer. We also prospected the research direction and development prospect of all-inorganic PSCs in the future. They had been highlighted in red color.
