Hole transport material (HTM) is an indispensable part of highly efficient perovskite solar cells (PSC). Designing new HTMs with suitable energy levels and desired electronic properties is critical to realize efficient and stable PSCs. Herein, two phenothiazine (PTZ) core building block based HTMs, termed PTZ-Py and PTZ-Bz, are reported. Applied in PSCs, the research results manifest that the introduced pyridine group, on the one hand, can deeply impact the electronic properties (energy levels and charge carrier mobility) and film-forming property; on the other hand, can efficiently passivate the perovskite surface defects, in turn, enhance the power conversion efficiency (PCE) and device stability. Under the optimized fabrication conditions, the HTM PTZ-Py based PSC obtains the highest PCE of 19.9%, and maintains around 90% initial efficiency after 1000 h aging in ambient condition with RH 50-65%. By using PTZ-Py as interface layer together with Spiro-OMeTAD, an improved PCE of 22.1% was obtained. The results came from multiple reactions, including the reaction of Bis(4-methoxyphenyl)amine(cas: 101-70-2Related Products of 101-70-2)

Recommanded Product: Bis(4-methoxyphenyl)amine The author mentioned the following in the article:

Hole-transport materials (HTMs) play a crucial role in determining the photovoltaic performance and long-term stability of perovskite solar cells (PSCs), because they not only efficiently facilitate hole-extraction and transfer, but also act as a barrier to protect the perovskite from moisture and oxygen. So far, the power conversion efficiencies (PCEs) over 20% in PSCs have been mostly achieved by employing a Spiro-OMeTAD-based HTM. However, it suffers from some drawbacks such as relatively low hole-mobility, complicated synthesis and difficult purification, which hamper its potential com. applications. Here, for the first time, two new easily accessible 9,9-bis(4-methoxyphenyl)-substituted fluorene-based HTMs comprising H (YT1) and methoxyphenyl-fluorene (YT3) as the terminated groups have been synthesized for use in organic-inorganic hybrid and all-inorganic PSCs. The (FAPbI3)0.85(MAPbBr3)0.15 and CsPbI2Br PSCs based on YT3 yield very impressive PCEs of 20.23% and 13.36%, resp., both of which are higher than that of Spiro-OMeTAD (19.18% and 12.30%). More encouragingly, the YT3-based PSC displays good long-term stability for 600 h. These results confirm that different terminated groups in HTMs show a significant effect on the energy levels, hole extraction and transfer, thin-film surface morphol. and photovoltaic performance. Our findings could provide a useful insight for future rational design of HTMs for highly efficient and stable PSCs.

In 2019,Journal of Materials Chemistry A: Materials for Energy and Sustainability included an article by Zhang, Yun; Kou, Chun; Zhang, Junjie; Liu, Yahui; Li, Wenhua; Bo, Zhishan; Shao, Ming. Formula: C14H15NO2. The article was titled 《Crosslinked- and dopant-free hole transport materials for efficient and stable planar perovskite solar cells》. The information in the text is summarized as follows:

The performance of p-i-n planar perovskite solar cells (PSCs) strongly depends on the electronic structure and interfacial properties of hole transporting materials (HTMs). Four diphenylamine derivatives with a fluorene core were synthesized and employed as hole transport layers in inverted p-i-n planar PSCs. HTMs that are endowed with vinyl crosslinking units can form insoluble 3-dimensional networks under mild annealing temperature, which improve the solvent resistance during the device fabrication and morphol. stability. Also, the optimized devices incorporating crosslinked HTMs exhibit an impressive power conversion efficiency of 18.7% with a high Jsc of 20.89 mA cm-2, Voc of 1.15 V and FF of 77.8%, which are superior to those of PEDOT:PSS based PSCs. The UPS measurement justifies that the new HTMs feature deep HOMO levels aligning well with the perovskite. Also, the hydrophobic nature of the synthesized HTMs favors the formation of large grained and continuous perovskite films with good surface coverage, evidenced by the H2O contact angles and film morphol. measurements. Steady-state and time-resolved photoluminescence studies also reveal that fast charge transfer and suppressed recombination occur between the perovskite and HTMs. Employing crosslinked organic HTMs is a promising approach to achieve high efficiency and stable PSCs.

And the article was published in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2019. Application In Synthesis of Bis(4-methoxyphenyl)amine The author mentioned the following in the article:

This study reports three newly developed dopant-free hole-transporting materials (HTMs) for perovskite solar cells. The design is based on a quinacridone (QA) dye as the core with three different extended end-capping moieties, namely, acenaphthylene (ACE), triphenylamine (TPA), and diphenylamine (DPA), attached to the QA core. These HTMs were synthesized and used to successfully fabricate in mesoscopic TiO2/CH3NH3PbI3/HTM perovskite devices. Under AM 1.5G illumination at 100 mW cm-2, the devices achieved a maximum efficiency of 18.2% for ACE-QA-ACE, 16.6% for TPA-QA-TPA and 15.5% for DPA-QA-DPA without any additives, whereas reference devices with doped spiro-OMeTAD as the HTM achieved a PCE of 15.2%. Notably, the unencapsulated devices based on the novel dopant-free HTMs exhibited impressive stability in comparison with the devices based on doped spiro-OMeTAD under a relative humidity of 75% for 30 days. These linear sym. HTMs pave the way to a new class of organic hole-transporting materials for cost-efficient and large-area applications of printed perovskite solar cells.

And the article was published in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2019. Application of 101-70-2 The author mentioned the following in the article:

Two novel phenothiazine 5,5-dioxide (PDO) core building block-based hole transport materials (HTMs), termed PDO1 and PDO2, were designed and synthesized. The introduction of a sulfuryl group in a core unit can deeply influence the energy levels and charge carrier mobilities of relative HTMs. The combined suitable energy level alignment, higher hole mobility and conductivity, as well as highly efficient hole transfer of PDO2 enable the perovskite solar cell (PSC) to achieve an impressive power conversion efficiency (PCE) of 20.2% and good stability when aged under ambient conditions. These results demonstrate the potential versatility of the PDO building block for further development of cost-effective and highly efficient HTMs for PSCs.
