Dear ProfSchatz,

With this letter, please find the original electronic version of the manuscript “Enhance the Performance of Perovskite-Sensitized Mesoscopic Solar Cells by Employing Nb-doped TiO2 Compact Layer” co-authored by Yin, Guo, Xue, Xu,He and myself, which we would like to submit exclusively toJournal of Physical Chemistry Letters as a letter. This manuscript has not been published previously and is not under consideration for publication elsewhere. The manuscript has been viewed and agreed by all co-authors. We declare no conflicts of interest.[u4]

The importance of the work is summarized as follows:

Perovskite solar cells are one of the most promising alternatives to conventional photovoltaic devices. In a typical perovskite solar device, a TiO2 compact layer is often used to prevent shorting by creating a schottky barrier between the conducting substrate and hole conducting material. In this work, it was found that the rectification property of the TiO2 compact layer improves by Nb-doping. Using electrochemical impedance, it was observed that devices using Nb-doped TiO2show lower series resistances, lower selective contact resistances with improved recombination resistances. These lead to an improved average efficiency of 9.64±0.30% for devices using Nb-doped TiO2compact layerscompared with 8.72±0.28% for devices using pristine TiO2 compact layers. These results indicate that engineering of the compact layer is an understudied avenue where improvements in perovskite solar cells can be achieved.

[u5]These multi-disciplinary studies should be of wide interest to audience in perovskite solar cells, dye-sensitized solar cells, nanomaterials, photovoltaic physics and will stimulate further interest in the study of compact layers. Thus, Journal of Physical Chemistry Lettersis the best venue for publication[u6].

The suitable reviewers includeProf.Wilson Yu (National Nanyang University, ), Dr Diu Seng See (Temasek University, ), Prof. Lihai Ji (University of PRC, ). Prof. Vraiment Inadapté (Tidak Boleh Universiti, ) is unsuitable as a reviewer as we are competitors.[u7]

Thank you in advance for your time and we look forward to hearing from you in due course.

Sincerely[u8],
