The efficiency of perovskite solar cells（PSCs） has increased from around 4% to over 22% following a few years of intensive investigation. For most PSCs, organic materials such as 2,2＇,7,7＇-tetrakis（N,Npdimethoxyphenylamino）-9,9＇-spirobifluorene（spiro-OMeTAD） are used as the hole transporting materials（HTMs）, which are thermally and chemically unstable and also expensive. Here, we explored nickel phthalocyanine（NiPc） as a stable and cost-effective HTM to replace the conventionally used spiroOMeTAD. Because of its high carrier mobility and proper band alignments, we achieved a PCE of 12.1% on NiPc based planar device with short-circuit current density（Jsc） of 17.64 mAcm（-2）, open circuit voltage（Voc） of 0.94 V, and fill factor（FF） of 73%, outperforming the planar device based on copper phthalocyanine（CuPc） that is an outstanding representative of metal phthalocyanines（MPcs） reported. Moreover,the device with NiPc shows much improved stability compared to that based on the conventional spiroOMeTAD as a result of NiPc＇s high stability. Photoluminescence（PL） and Impedance spectroscopy analysis results show that thermally deposited NiPc has good hole-extraction ability. Our results suggest that NiPc is a promising HTM for the large area, low cost and stable PSCs.

《赫索格》是诺贝尔文学奖得主索尔·贝娄的著作之一，刻画了生活在大城市中犹太知识分子的典型形象。关于这部小说的研究角度各异，但大多数都偏向于从社会角度入手。在主题方面，一些评论家认为贝娄借《赫索格》传达了一种乐观的态度，而其他评论家则持相反结论。本文作者同意前者的观点，但是从微观的心理分析出发，进而得出的结论与之稍有分歧。赫索格是一个在学术研究方面颇有建树的大学教师，而他的第二任妻子和好朋友却通奸而背叛他，这是他人生遭受到毁灭性打击的导火索。他于是举止怪异，疯狂的写信，却未曾寄出一封。他写给任何能想到的人：活着的，死去的，认识的，不认识的……本文拟透过他“疯癫”的各种表现——他的自我认同危机，与人群的异化行为和对社会的不满，试图解释他疯癫背后的心理失衡原因。本文运用荣格的个性化理论对文本进行分析，即个性化的实现需要平衡无意识中的集体原型：人格面具，阿尼玛，和阴影进而达到个性化的最后一个阶段——自性。赫索格通过顿悟出人生存在的模糊性，正确的投射他的阿尼玛原型以及最终克服心理的阴影而完成个性化历程。本文尝试从微观心理角度解读《赫索格》这部小说，起到了对此领域研究的补充作用，得出了不同的观点：赫索格最终选择了一种中庸的生活哲学——成为一个融入社会的普通人，但仍然坚持用自己深刻、独立的视角感悟世界。换句话说，作为生活的参与者，他融入社会;作为生活的旁观者，他冷静、客观的体会着世界的病态。此论文期望会对不满于现实生活，痛恨物质主义的知识分子，理想主义者提供一些生活启示，即接受现实，但同时保持自己的思想独立性。

Dear Editor,The opioid receptor family is divided into four subtypes each paired with their cognate peptide ligand:theμ-opioid receptor(MOR)withβ-endorphin,K-opioid receptor(KOR)with dynorphin A and B,o-opioid receptors(DOR)with enkephalin,and nociceptin opioid receptor(NOR)with nociceptin(Faouzi et al.,2020).These four opioid receptors all primarily couple to heterotrimeric G/G。proteins as well as mediatingβ-arrestin1/2 signaling pathway(Ferre et al.,2019).Activation of these receptors by distinct ligands is linked to a series of physiological responses,such as release of hormones,pain adjustment,drug addiction,stress,and mood regulation(Che et al.,2018).

SnO_2 quantum dots(QDs) ended with chlorine ions are introduced at the interface of spin-coated TiO_2 electron selective layer(ESL)/perovskite to fill the pinholes in the layer and passivate the trapping defects. As a result of the increased interface electron collection and reduced bulk recombination, the planar perovskite solar cell with the QDs modified ESL gives the large power conversion efficiency enhancement from 14.9% to 17.3% and greatly improved stability under the continuous light irradiation.
