The Font Cover shows a SnO_x thin film deposited through sputtering with oxygen vacancies to be used as electron transporting layer (ETL) in perovskite solar cells (PSCs). The role of oxygen vacancies was found to be crucial for engineering the electrical and optical properties of the SnO_x film. This research demonstrates a facile approach for creating different amounts of oxygen vacancies in SnO_x films using in situ substrate heating by sputtering deposition. The work demonstrates manipulation of the conduction‐band position of the SnO_x film by tuning the oxygen vacancy to achieve favorable energy alignment between the ETL and perovskite layer for higher energy conversion efficiency of PSCs. These results demonstrate that introducing oxygen vacancies into SnO_x films can benefit the device performance.

前封面：调整溅射沉积SnOx膜中的氧空位量以增强钙钛矿太阳能电池的性能（ChemSusChem 18/2018）

字体封面显示了通过氧空位溅射沉积的SnO _x薄膜，可用作钙钛矿太阳能电池（PSC）中的电子传输层（ETL）。发现氧空位的作用对于工程化SnO _x膜的电学和光学性质至关重要。这项研究表明，通过溅射沉积原位加热衬底，可以在SnO _x薄膜中产生不同数量的氧空位的简便方法。该作品演示了SnO _x导带位置的操纵通过调节氧空位来实现ETL和钙钛矿层之间良好的能量排列，从而提高PSC的能量转换效率。这些结果表明，在SnO _x薄膜中引入氧空位可有益于器件性能。可以在Ali等人的《全文》中找到更多信息。就在第18期，2018页3096（：10.1002 / cssc.201801541 DOI）。
