Abstract

In this report, highly efficient and humidity-resistant perovskite solar cells (PSCs) using two new small molecule hole transporting materials (HTM) made from a cost-effective precursor anthanthrone (ANT) dye, namely, 4,10-bis(1,2-dihydroacenaphthylen-5-yl)-6,12-bis(octyloxy)-6,12-dihydronaphtho[7,8...

ACE-ANT-ACE and TPA-ANT-TPA are used as a dopant-free HTM in mesoscopic TiO2/CH3NH3PbI3/HTM solid-state PSCs, and the performance as well as stability are compared with Spiro-OMeTAD-based PSCs. After extensive optimization of the metal oxide scaffold and device processing conditions, dopant-free novel TPA-ANT-TPA HTM-based PSC devices achieve a maximum power conversion efficiency (PCE) of 17.5% with negligible hysteresis. An impressive current of 21 mA cm&#x2212;2 is also confirmed from photocurrent density with a higher fill factor of 0.79. The obtained PCE of 17.5% utilizing TPA-ANT-TPA is higher performance than the devices prepared using doped Spiro-OMeTAD (16.8%) as hole transport layer at 1 sun condition. It is found that doping of LiTFSI salt increases hygroscopic characteristics in Spiro-OMeTAD; this leads to the fast degradation of solar cells. While, solar cells prepared using undoped TPA-ANT-TPA show dewetting and improved stability. Additionally, the new HTMs form a fully homogeneous and completely covering thin film on the surface of the active light absorbing perovskite layers that acts as a protective coating for underlying perovskite films. This breakthrough paves the way for development of new inexpensive, more stable, and highly efficient ANT core based lower cost HTMs for cost-effective, conventional, and printable PSCs.</abstract><type>Journal Article</type><journal>Advanced Energy Materials</journal><paginationStart>1703007</paginationStart><publisher/><issnPrint>16146832</issnPrint><keywords>anthanthrone dye; high efficiency; high stability; low-cost hole transporting materials; perovskite solar cells</keywords><publishedDay>31</publishedDay><publishedMonth>12</publishedMonth><publishedYear>2018</publishedYear><publishedDate>2018-12-31</publishedDate><doi>10.1002/aenm.201703007</doi><url>https://www.youtube.com/watch?v=hgLkeFves7o&amp;amp;feature=youtu.be</url><notes/><college>COLLEGE NANME</college><department>Materials Science and Engineering</department><CollegeCode>COLLEGE CODE</CollegeCode><DepartmentCode>MTLS</DepartmentCode><institution>Swansea University</institution><apcterm/><lastEdited>2018-05-09T16:01:56.9440837</lastEdited><Created>2018-02-20T12:18:59.7572300</Created><path><level id="1">Faculty of Science and Engineering</level><level id="2">School of Engineering and Applied Sciences - Materials Science and Engineering</level></path><authors><author><firstname>Hong Duc</firstname><surname>Pham</surname><order>1</order></author><author><firstname>Thu Trang</firstname><surname>Do</surname><order>2</order></author><author><firstname>Jinhyun</firstname><surname>Kim</surname><order>3</order></author><author><firstname>Cecile</firstname><surname>Charbonneau</surname><orcid>0000-0001-9887-2007</orcid><order>4</order></author><author><firstname>Sergei</firstname><surname>Manzhos</surname><order>5</order></author><author><firstname>Krishna</firstname><surname>Feron</surname><order>6</order></author><author><firstname>Wing Chung</firstname><surname>Tsoi</surname><order>7</order></author><author><firstname>James</firstname><surname>Durrant</surname><orcid>0000-0001-8353-7345</orcid><order>8</order></author><author><firstname>Sagar</firstname><surname>Jain</surname><order>9</order></author><author><firstname>Prashant</firstname><surname>Sonar</surname><order>10</order></author><author><firstname>Wing Chung</firstname><surname>Tsoi</surname><orcid>0000-0003-3836-5139</orcid><order>11</order></author></authors><documents><document><filename>0038797-26022018165318.pdf</filename><originalFilename>pham2018.pdf</originalFilename><uploaded>2018-02-26T16:53:18.2630000</uploaded><type>Output</type><contentLength>2393869</contentLength><contentType>application/pdf</contentType><version>Accepted Manuscript</version><cronfaStatus>true</cronfaStatus><embargoDate>2019-02-19T00:00:00.0000000</embargoDate><copyrightCorrect>true</copyrightCorrect><language>eng</language></document></documents><OutputDurs/></rfc1807>
