PBDB-T-2F（或PM6）是一种包含氟化噻吩基苯并二噻吩（BDT-2F）的宽带隙聚合物供体（N型半导体），用于高性能聚合物太阳能电池（PSC）。PBDB-T-2F具有高结晶性和强烈的π-π堆积排列，有利于电荷载流子的传输，从而抑制了器件中的重组。据报道，基于PBDBT-2F的PSC具有厚度和面积不敏感的性能，并且是大规模滚动制造高效聚合物太阳能电池的有前途的候选者。
例如，最近，新的研究表明，基于pBDB-T-2F:IT-4F的PSC产生了令人印象深刻的PCE，为13.5%，这是由于供体和受体上氟化的协同效应，这是迄今为止PSC文献中记录的最高值之一。基于PBDB-T-2F:IT-4F的PSC相对于有效性也显示出良好的存储，热和照明稳定性。在广泛的膜面积和厚度范围内，高效性保持在>11%。当与基于硒代苯[3，2-b]噻吩的窄带隙非富勒烯受体配对时，获得了令人印象深刻的13.3%的有效性，具有厚度不敏感的特征。
以前也有报道，PBDB-T-2F与窄带隙小分子受体2，2′-（（2Z，2′Z）-（（4，4，9，9-四己基-4，9-二氢-s-茚并[1，2-b:5,6-b′]二噻吩-2，7-二基）双（亚甲基））双（3-氧代-2，3-二氢-1H-茚-2，1-二亚基））二丙二腈（IDIC），铸态薄膜（未经额外处理）显示出11.9%[1]的出色功率转换有效性（PCE），是铸态聚合物太阳能电池的记录值。此外，基于PBdB-T-2F:IDIC的器件的性能对有源层厚度（≅95-255 nm）和器件面积（0.20-0.81 cm2）不敏感，因此是未来卷到卷的有希望的候选者批量制造和高效PSC的实际应用。
PBDB-T-2F在300-685 nm的短波长范围内具有很强的吸收，具有1.80 eV的大带隙，与ITIC（1.55 eV）互补，有助于实现PSC中的高短路电流（Jsc）。此外，PBDB-T-2F显示出−5.50 eV的深HOMO水平，强结晶性和堆积的主要面，这有助于在PSC中实现高开路电压（Voc）并填充因子（FF）。

OPV Device Performance:

PBDB-T-2F (or PM6) is a wide bandgap polymer donor (n-type semiconductor) containing fluorinated thienyl benzodithiophene (BDT-2F) used in high performance polymer solar cells (PSCs). PBDB-T-2F possesses high crystallinity and strong π-π stacking alignment, which are favourable to charge carrier transport and hence suppress recombination in devices. PBDBT-2F based PSCs were reported to have thickness and area insensitive performance and is a promising candidate for large-scale roll-to-roll manufacturing of high-efficiency polymer solar cells.
For example, recently, new study have shown PBDB-T-2F:IT-4F based PSCs yielded an impressive PCE of 13.5% due to the synergistic effect of fluorination on both donor and acceptor, which is among the highest values recorded in the literatures for PSCs to date . The PBDB-T-2F:IT-4F baed PSCs also showed good storage, thermal and illumination stabilities with respect to the efficiency. High efficiency of >11% was maintained for a wide range of film area and thickness. When paired with selenopheno[3,2-b]thiophene-based narrow-bandgap non-fullerene acceptor, an impressive efficiency of 13.3 % was obtained with thickness-insensitive feature.
It has also been previously reported, PBDB-T-2F when paired with narrow band-gap small molecule acceptor 2,2′-((2Z,2′Z)-((4,4,9,9-tetrahexyl-4,9-dihydro-s-indaceno[1,2-b:5,6-b′]dithiophene-2,7-diyl)bis(methanylylidene))bis(3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile (IDIC), the as-cast film (without extra treatments) showed an outstanding power conversion efficiency (PCE) of 11.9%[1], a record value for as-cast polymer solar cells. Moreover, the performance of PBDB-T-2F:IDIC based devices is insensitive to the active layer thickness (≅95-255 nm) and device area (0.20-0.81 cm2), and thus is a promising candidate for future roll-to-roll mass manufacturing and practical application of highly efficient PSCs.
It has also been reported, PBDB-T-2F possesses a strong absorption in the short wavelength region of 300-685 nm with a large bandgap of 1.80 eV, which is complementary to that of ITIC (1.55 eV) and facilitates achieving high short-circuit current (Jsc) in PSCs. Moreover, PBDB-T-2F shows a deep HOMO level of −5.50 eV, a strong crystallinity and a dominant face on packing, which helps to achieve a high open-circuit voltage (Voc) and fill factor (FF) in PSCs.
