摘要

使用纹理透明导电薄膜的有机-无机卤化物过氧化物太阳能电池具有较高的效率，短路电流密度也有所提高。然而，通过溶液工艺在纹理上均匀沉积电子传输层（ETL）具有挑战性。在这项研究中，通过依次旋涂带正负电荷段的聚电解质和带负电荷的二氧化硒胶体溶液，并以静电方式提高二氧化硒的覆盖率，形成了均匀的 ETL。通过加入这种聚电解质/二氧化锡双电层，稳定功率输出（SPO）从 12.9% 提高到 18.6%。

Polyelectrolyte-assisted uniform electron transporting layer on texture substrate for perovskite solar cells

Organic-inorganic halide perovskite solar cells using textured transparent conductive films exhibit high efficiencies with improved short-circuit current density. However, uniform electron transport layer (ETL) deposition on textures by solution process is challenging. In this study, uniform ETL were formed by sequentially spin-coating polyelectrolyte with positively and negatively charged segments and negative SnO2 colloids solution and electrostatically enhancing the SnO2 coverage. The stabilized power output (SPO) was improved from 12.9% to 18.6% by incorporating this polyelectrolyte/SnO2 bilayer.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
