Molecular Engineering of Soluble Metal Phthalocyanine based Hole Transporting Materials for Perovskite Solar Cells

第六届新型太阳能电池材料科学与技术学术研讨会

作者： Qikun Hu minzhang li Zongxiang Xu Department of Chemistry Southern University of Science and Technology

Efficient and stable hole transporting materials(HTMs) are necessary for perovskite solar cells(PSCs) with excellent efficiencies and long-term stability. Here, we prepared two A3B-type metal phthalocyanine(MPc) compounds as dopant free HTMs and employed in conventional n-i-p structured PSCs. H6Bu-ZnPc and Me6Bu-ZnPc were synthesized through ring expansion method and their exact structures were characterized by NMR and Mass spectroscopy. The molecular orientation of the developed HTM thin films against the underlying surface was studied using X-ray diffraction technique. Different substituents in MPcs can strongly affect their molecular orientation and intermolecular π-π stacking, resulting in different hole mobilities. The favored face-on molecular alignment was only observed for Me6Bu-ZnPc on perovskite layer, proving the crucial role of methyl substituents in controlling the molecular alignment through the especial interactions between the MPc molecule and different sites of perovskite material on the surface. PSCs using Me6Bu-ZnPc as dopant free HTM achieved the highest power conversion efficiency(PCE) of 17.41%, which is consistent with the observed higher short circuit current density(JSC) and fill factor(FF). With its high hydrophobicity and good coverage, Me6Bu-ZnPc HTM thin film acted as an encapsulation layer and a significantly increased long-term stability was obtained for the devices. The Me6Bu-ZnPc based devices retained over 90% of their initial PCE after 1400 hours storage at 25oC and with a relative humidity of 75%.

Fast period estimation of X-ray pulsar signals using an improved fast folding algorithm

Metal phthalocyanines can effectively act as alternative dopant-free small molecule hole transporting materials in perovskite solar cells(PSC).[1] In order to increase solubility and the hole transport ability, tetral substituted copper phtalocyanines have been synthesized and were compared to commercially available hole transporting material of spiro-OMeTAD.[2, 3] It was found that the configuration of the substituents play a rather dramatic role in molecular alignment and in the subsequent performance of solar cells(Figure 1). Tetra-methoxytriphenylamine derivative(OMe-TPA-CuPc) being the most effective hole transporter, not only increase the device efficiency(19.7%) but also the stability(800 h).

Using bathymetry and altimetric gravity anomalies, a 1°×9 1° lithospheric effective elastic thickness（Te） model over the Louisville Ridge and its adjacent regions is calculated using the moving window admittance technique. For comparison, three bathymetry models are used： general bathymetric charts of the oceans, SIO V15.1,and BAT_VGG. The results show that BAT_VGG is more suitable for calculating T e than the other two models. T e along the Louisville Ridge was re-evaluated. The southeast of the ridge has a medium Te of 10–20 km, while Te increases dramatically seaward of the Tonga-Kermadec trench as a result of the collision of the Pacific and IndoAustralian plates.

Using mobile gravity data from the central area of Sichuan and Yunnan Provinces, the relationship between gravity variation and earthquakes was studied based on the Ludian Ms6.5 earthquake that occurred on August 3rd, 2014, and the Kangding Ms6.3 earthquake that occurred on November 22 nd, 2014; the mechanism of gravity variation was also explored. The results are as follows：（1） Prior to both earthquakes, gravity variation exhibited similar characteristics as those observed before both the Tangshan and Wenchuan earthquakes, in which typical precursor anomalies were positive gravity variation near the epicenter and the occurrence of a high-gravity-gradient zone across the epicenter prior to the earthquake.（2） A relatively accurate prediction of the occurrence locations of the two earthquakes was made by the Gravity Network Center of China（GNCC） based on these precursor anomalies. In the gravity study report on the 2014 earthquake trends submitted at the end of 2013, the Daofu-Shimian section at the junction of the Xianshuihe and Longmenshan fault zones was noted as an earthquake-risk region with a predicted magnitude of 6.5, which covered the epicenter of the Kangding Ms6.3 earthquake. In another report on earthquake trends in southwestern China submitted in mid-2014, the lianfeng, Zhaotong fault zone was also classified as an earthquake-risk region with a magnitude of 6.0, and the central area of this region basically overlapped with the epicenter of the Ludian Ms6.5 earthquake.（3） The gravity variation characteristics are reasonably consistent with crustal movements, and deep material migration is likely the primary cause of gravity variation.

The relationship between gravity variation and the Akto Ms6.7 earthquake on November 11, 2016, was studied by use of mobile gravity observation data from the China continental structural environmental monitoring network. The result revealed that before the Akto earthquake, a high positive gravity variation was observed in the Pamir tectonic knots region （within a maximum magnitude of approximately ＋80 microgal）, which was consistent with the existing knowledge of gravity abnormality and the locations of strong earthquakes. In view of the recent strong seismic activities in the Pamir tectonic knots region, as well as the strong upward crust movement and compressive strain, it is believed that gravity change in the Pamir tectonic knots region reflects the recent strong seismic activities and crust movement.

Tea domain transcription factor 4 (TEAD4) plays a pivotal role in tissue development and homeostasis by interacting with Yesassociated protein (YAP) in response to Hippo signaling inactivation. TEAD4 and YAP can also cooperate with transforminggrowth factor-β (TGF-β)-activated Smad proteins to regulate gene transcription. Yet, it remains unclear whether TEAD4 playsa YAP-independent role in TGF-β signaling. Here, we unveil a novel tumor suppressive function of TEAD4 in liver cancer viamitigating TGF-β signaling. Ectopic TEAD4 inhibited TGF-β-induced signal transduction, Smad transcriptional activity, and targetgene transcription, consequently suppressing hepatocellular carcinoma cell proliferation and migration in vitro and xenografttumorgrowth in mice. Consistently, depletion of endogenous TEAD4 by siRNAs enhanced TGF-β signaling in cancer cells. Mechanistically,TEAD4 associates with receptor-regulated Smads (Smad2/3) and Smad4 in the nucleus, thereby impairing the binding of Smad2/3to the histone acetyltransferase p300. Intriguingly, these negative effects of TEAD4 on TGF-β/Smad signaling are independent ofYAP, as impairing the TEAD4–YAP interaction through point mutagenesis or depletion of YAP and/or its paralog TAZ has little ***, these results unravel a novel function of TEAD4 in fine tuning TGF-β signaling and liver cancer progression in a YAPindependent manner.

In this paper, the admittance function between seafloor undulations and vertical gravity gradient anomalies was derived. Based on this admittance function, the bathymetry model of 1 minute resolution was predicted from vertical gravity gradient anomalies and ship soundings in the experimental area from the northwest Pacific. The accuracy of the model is evaluated using ship soundings and existing models, including ETOPO1, GEBCO, DTU10 and V15.1 from SIO. The model＇s STD is 69. 481m, comparable with V15.1 which is generally believed to have the highest accuracy.
