Conjugated polyelectrolytes (CPEs) exhibit intriguing advantages as HTLs, such as tunable properties and excellent solution processability, but they suffer from poor charge\u2010transporting properties, resulting in inferior performance to traditional HTLs. Herein, a series of pH\u2010neutral CPEs are designed and synthesized that can form enhanced crystalline and highly ordered films. By tailoring trifluoromethyl substituents on the triphenylamine unit, TMPT\u2010F exhibited exceptional long\u2010range molecular ordering and compact laminar packing, along with a crystalline coherence length of 2.56 nm and a laminar packing distance of 1.48 nm, ultimately yielding an unprecedented conductivity of 3.3 \u00d7 10\n                    <jats:sup>\u22122<\/jats:sup>\n                    S\u00a0m\n                    <jats:sup>\u22121<\/jats:sup>\n                    for the CPE\u2010based HTL. The substantially enhanced charge\u2010transporting property of the PMA\u2010doped TMPT\u2010F:PMA greatly suppressed the charge recombination in OSCs. The OSC modified by the TMPT\u2010F:PMA HTL exhibited a PCE as high as 19.24%, which is superior to the PEDOT:PSS device. Moreover, TMPT\u2010F:PMA showed excellent compatibility with flexible electrode, enabling a PCE of 16.52% for flexible OSC, and the device retained 83% of the initial PCE even after a 500\u2010cycle bending at 5 mm radius.\n                  <\/jats:p>","DOI":"10.1002\/adma.202509995","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T07:52:16Z","timestamp":1753257136000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Conjugated Polyelectrolyte with Long\u2010Range Ordering and Compact Molecular Packing as Hole\u2010Transporting Material for Efficient and Flexible Organic Solar Cells"],"prefix":"10.1002","volume":"37","author":[{"given":"Yao","family":"Tong","sequence":"first","affiliation":[{"name":"State Key Laboratory of Chemical Resource Engineering College of Materials Science and Engineering Beijing University of Chemical Technology  Beijing 100029 P.
