Unlike traditional methods that enhance the performance of NiOx through reactive sputtering or directly doping NiOx targets with metal ions, both of which incur high costs and low efficiency, we employ an evaporation method using LiF to achieve efficient and low-cost doping of NiOx. Compared to the pristine NiOx, the incorporation of LiF significantly increases the conductivity of NiOx. Additionally, the incorporation of LiF enhances the quality of the deposited perovskite films, as well as the energy level alignment and symmetry between NiOx and the perovskite, effectively improving the hole extraction and transport capabilities between NiOx and the perovskite. As a result, the PSM (active area of 57.30 cm\u00b2) fabricated in air achieves an impressive efficiency of 19.54%. Furthermore, the unencapsulated PSM retains 80% of its initial efficiency after 700 h of continuous illumination, whereas the NiOx-based PSM drops to 80% after only 150 h. This study provides a simple and low-cost method for doping NiOx, which is of great significance for the further industrialization of PSMs.<\/jats:p>","DOI":"10.3390\/sym16101357","type":"journal-article","created":{"date-parts":[[2024,10,14]],"date-time":"2024-10-14T04:02:58Z","timestamp":1728878578000},"page":"1357","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Enhancing Conductivity of Nickel Oxide to Achieve Scalable Preparation for High-Efficiency Perovskite Solar Modules"],"prefix":"10.3390","volume":"16","author":[{"given":"Lei","family":"Wang","sequence":"first","affiliation":[{"name":"School of Optoelectronic Science and Engineering, University of Electronic Science and Technology of China, Chengdu 610054, China"}]},{"given":"Xiaobo","family":"Li","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Science and Engineering, University of Electronic Science and Technology of China, Chengdu 610054, China"}]},{"given":"Shihao","family":"Yuan","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Science and Engineering, University of Electronic Science and Technology of China, Chengdu 610054, China"}]},{"given":"Feng","family":"Qian","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Science and Engineering, University of Electronic Science and Technology of China, Chengdu 610054, China"}]},{"given":"Zhangli","family":"Kang","sequence":"additional","affiliation":[{"name":"National Institute of Measurement and Testing Technology, Chengdu 610021, China"}]},{"given":"Shibin","family":"Li","sequence":"additional","affiliation":[{"name":"School of Optoelectronic Science and Engineering, University of Electronic Science and Technology of China, Chengdu 610054, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"536","DOI":"10.1038\/s41586-024-07723-3","article-title":"Buried interface molecular hybrid for inverted perovskite solar cells","volume":"632","author":"Liu","year":"2024","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"433","DOI":"10.1126\/science.adn9453","article-title":"Operationally stable perovskite solar modules enabled by vapor-phase fluoride treatment","volume":"385","author":"Zhao","year":"2024","journal-title":"Science"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"2313860","DOI":"10.1002\/adma.202313860","article-title":"Suppressing Ion Migration by Synergistic Engineering of Anion and Cation toward High-Performance Inverted Perovskite Solar Cells and Modules","volume":"36","author":"Zhang","year":"2024","journal-title":"Adv.
