This study presents experimental evidence of the dependence of non-radiative recombination processes on the electron-phonon coupling of perovskite in perovskite solar cells(PSCs).Via A-site cation engineering,a weaker electron-phonon coupling in perovskite has been achieved by introducing the structurally soft cyclohexane methylamine(CMA^(+))cation,which could serve as a damper to alleviate the mechanical stress caused by lattice oscillations,compared to the rigid phenethyl methylamine(PEA^(+))*** demonstrates a significantly lower non-radiative recombination rate,even though the two types of bulky cations have similar chemical passivation effects on perovskite,which might be explained by the suppressed carrier capture process and improved lattice geometry *** resulting PSCs achieve an exceptional power conversion efficiency(PCE)of 25.5%with a record-high opencircuit voltage(V_(OC))of 1.20 V for narrow bandgap perovskite(FAPbI_(3)).The established correlations between electron-phonon coupling and non-radiative decay provide design and screening criteria for more effective passivators for highly efficient PSCs approaching the Shockley-Queisser limit.

目的探讨溃疡性结肠炎(UC)患者行腹腔镜下全结直肠切除(TPC)联合回肠储袋肛管吻合术(IPAA)的术后早期(<30 d)并发症发生的相关危险因素。方法回顾性收集解放军东部战区总医院普通外科炎症性肠病治疗中心2014年1月至2018年6月行腹腔镜下TPC+IPAA治疗的UC患者的临床资料。根据术后30 d是否发生并发症进行分组,采用单因素和多因素方法分析术后早期并发症发生情况及相关危险因素。结果132例患者行腹腔镜下TPC+IPAA术,男性70例,女性62例,中位年龄42(16~72)岁,41例(31.1%)患者发生60例次术后早期并发症,其中储袋出血9例次(6.8%),储袋相关瘘及腹腔和盆腔感染10例次(7.6%),小肠梗阻13例次(9.8%),术后胃排空障碍15例次(11.4%),切口及肺部感染等13例(9.8%)。术前白蛋白<35.0 g/L(P=0.012)和术前使用激素≥20 mg/d超过6周(P=0.030)是术后早期并发症发生的独立危险因素。结论腹腔镜下TPC+IPAA是治疗UC安全且有效的方式,提高患者术前白蛋白水平及优化患者术前激素治疗方案对降低术后早期并发症风险具有重要意义,二期IPAA手术并未增加术后并发症的风险。
