Thanks for reviewing the article.
Reviewer 2 Report
This paper presented the simulation of methyl ammonium tin bromide solar cells by SCAPS-1D. The results clearly exhibited the tolerance of defect density in the absorber layer and the interfaces are 1015 and 1014 cm-3, respectively. These simulated results are interesting to some researchers. I suggested that this paper can be accepted. However, the whole manuscript English should be revised carefully before publication. For example, there is incomplete sentence at line 278, etc.

Reviewer 3 Report
The manuscript is presenting an interesting topic on the simulation of Sn-based perovskites. A number of parameters such as defect conc. and Nd and WF have been optimized. However,the few comments below are essential before we proceed with this publication:
-table I, the Eg of perovskite is 0.5 ev? but the band diagram shows it is 1.08 ev.
-it must be explained why rising the defect will reduce the Jsc and FF after concentration passed 10^14.
-citation is required to DOI: 10.1007/s11082-019-1802-3
-at the HTL defect is damaging Jsc. but not clear why. this could be well explained as it can be a guide for an experimentist.
-fig. 6 is not labeling the data.can't compare.
-why the V_bi is decreasing by increased voltage and C and Nt? I don't see this correlation with Fig. 7b thou.
when authors take my comments in and answer my Qs, i can reconsider my decision.
