The Role of Dimethylammonium Iodide in CsPbI3 Perovskite Fabrication: Additive or Dopant?

摘要

Abstract > The controllable growth of CsPbI <sub>3</sub> perovskite thin films with desired crystal phase and morphology is crucial for the development of high efficiency inorganic perovskite solar cells (PSCs). The role of dimethylammonium iodide (DMAI) used in CsPbI <sub>3</sub> perovskite fabrication was carefully investigated. We demonstrated that the DMAI is an effective volatile additive to manipulate the crystallization process of CsPbI <sub>3</sub> inorganic perovskite films with different crystal phases and morphologies. The thermogravimetric analysis results indicated that the sublimation of DMAI is sensitive to moisture, and a proper atmosphere is helpful for the DMAI removal. The time‐of‐flight secondary ion mass spectrometry and nuclear magnetic resonance results confirmed that the DMAI additive would not alloy into the crystal lattice of CsPbI <sub>3</sub> perovskite. Moreover, the DMAI residues in CsPbI <sub>3</sub> perovskite can deteriorate the photovoltaic performance and stability. Finally, the PSCs based on phenyltrimethylammonium chloride passivated CsPbI <sub>3</sub> inorganic perovskite achieved a record champion efficiency up to 19.03?%. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > CSPBI的可控增长 <sub> 3 </ sub> 具有所需晶相和形态的钙钛矿薄膜对高效无机钙钛矿太阳能电池（PSC）的发展至关重要。 CSPBI中使用的二甲基碘化物（DMAI）的作用 <sub> 3 </ sub> 钙钛矿制造经过仔细研究。我们证明DMAI是一种有效的挥发性添加剂，以操纵CSPBI的结晶过程 <sub> 3 </ sub> 无机钙钛矿膜，具有不同的晶相和形态。热重分析结果表明DMAI的升华对水分敏感，并且适当的气氛有助于DMAI去除。飞行时间二次离子质谱和核磁共振结果证实DMAI添加剂不会合金到CSPBI的晶格中 <sub> 3 </ sub> Perovskite。此外，CSPBI中的DMAI残留物 <sub> 3 </ sub> Perovskite可以恶化光伏性能和稳定性。最后，基于苯基三甲基氯化铵的PSC钝化CSPBI <sub> 3 </ sub> 无机钙钛矿达到了高达19.03的冠军效率。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-19011/'>《Angewandte Chemie》</a> <b style="margin: 0 2px;">|</b><span>2019年第46期</span><b style="margin: 0 2px;">|</b><span>共6页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1188.html" title="应用化学">应用化学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=additive&option=203" rel="nofollow">additive;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=all-inorganic perovskite&option=203" rel="nofollow">all-inorganic perovskite;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Cl doping&option=203" rel="nofollow">Cl doping;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=CsPbI3&option=203" rel="nofollow">CsPbI3;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=dimethylammonium iodide&option=203" rel="nofollow">dimethylammonium iodide;</a> </p> <div class="translation"> 机译：添加剂;全无机钙钛矿;Cl掺杂;cspbi3;二甲基铵碘化物; </div> </li> </ul> </div> </div> <div class="literature cardcommon"> <div class="similarity "> <h3 class="all_title" id="enpatent66">相似文献</h3> <div class="similaritytab clearfix"> <ul> <li class="active" >外文文献</li> <li >中文文献</li> <li >专利</li> </ul> </div> <div class="similarity_details"> <ul > <li> <div> <b>1. </b><a class="enjiyixqcontent" href="/journal-foreign-detail/0704028165317.html">The Role of Dimethylammonium Iodide in CsPbI3 Perovskite Fabrication: Additive or Dopant?</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor"> </a> <a href="/journal-foreign-19011/" target="_blank" rel="nofollow" class="tuijian_authcolor">Angewandte Chemie .</a> <span>2019</span><span>,第46期</span> </span> </div> <p class="zwjiyix translation" style="max-width: initial;height: auto;word-break: break-all;white-space: initial;text-overflow: initial;overflow: initial;"> <span>机译：二甲基碘化物在CSPBI3钙钛矿制造中的作用：添加剂或掺杂剂？</span> </p> </li> <li> <div> <b>2. </b><a class="enjiyixqcontent" href="/academic-journal-foreign_materials-letters_thesis/0204112794117.html">Fabrication of hole-transport-free perovskite solar cells using 5-ammonium valeric acid iodide as additive and carbon as counter electrode</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Santhosh N.&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor">Santhosh N.,</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sitaaraman S.
