第七届新型太阳能电池材料科学与技术学术研讨会

作者： Jianfeng Lu zihao tang Fuzhi Huang Yi-Bing Cheng Wuhan University of Technology

High efficiency and environmental stability are mandatory performance requirements for commercialization of perovskite solar cells(PSCs).Herein,efficient cm-scale PSCs with improved stability were achieved by incorporating an additive-free spiro-OMeTAD hole transporting material(HTM) through simply substituting the usual chlorobenzene solvent with pentachloroethane(PC).A stabilized power conversion efficiency of 16.1% under simulated AM 1.5 G 1-sun illumination with an aperture of 1.00 cm2 was achieved for PSCs using an additive-free spiro-OMeTAD layer cast from PC.X-ray analysis suggested chlorine radicals from pentachloroethane transferred partially to spiro-OMeTAD and retain in the HTM film,resulting of conductivity ***,unencapsulated PSCs having cm-scale active area cast from PC retained>70% of their initial PCE after ageing at 80 °C for 500 h,in contrast with less than 20% retention for control *** and X-ray analysis of the aged cells revealed that the perovskite and HTM layers remain almost unchanged in the cells with spiro-OMeTAD layer cast from PC whereas serious degradation occurred in the control cells. This study not only reveals the decomposition mechanism of PSCs in the presence of HTM-additives,but also opens up a broad range of organic semiconductors for radical doping.

香果树是中国特有的单种属孑遗树种,探讨末次冰盛期以来香果树在中国的潜在地理分布格局及其变化,对研究茜草科乃至中国亚热带植物区系的系统发育、古生态和古气候变迁等具有重要作用。研究基于最大熵MaxEnt模型与ArcGIS空间分析技术,利用香果树分布点位信息与气候数据,构建其在末次冰盛期(LGM)、全新世中期(MID)、当前(1960—1990年)以及未来(2061—2080年)的潜在地理分布格局,探明其分布格局的变化趋势,揭示引起其潜在地理分布格局改变的关键因子。结果表明,香果树当前适生区总面积约197.575×10^(4)km^(2),主要位于中国亚热带地区,其中高适生区集中分布于四川盆周山地、武陵山与武夷山地区,最干季度平均温、最湿月降水量、最冷季度降水量是限制其分布的主要气候因子。末次冰盛期时香果树广泛分布于中国亚热带地区,随后适生区开始缩减且向内陆退缩,全新世中期后适生区面积继续缩减并向高纬度地区迁移。随着全球气候变暖,在不同排放情景下香果树适宜生境面积均进一步缩减并向西与高纬度地区迁移。总体而言,从末次冰盛期至未来,香果树适生区呈现持续缩减并向西与高纬度地区迁移的趋势,建议对现存香果树群体进行实时监测、人工繁育以及迁地保存。

针对车联网轨迹发布中用户面临的隐私泄露问题,提出基于聚类和深度学习的轨迹隐私保护机制(PPCDL).考虑轨迹中的时间因素,通过时间戳将轨迹空间划分为多个区域,获取区域中的轨迹分布点.对每个区域进行改进稳定隶属度多峰值聚类,根据区域轨迹密度进行隐私预算矩阵的预分配.利用时间图卷积网络模型提取轨迹数据的时空特征,对隐私预算预分配矩阵进行训练和预测.根据预测结果添加相应的拉普拉斯噪声,在轨迹数据发布前进行扰动.理论分析和实验结果表明,PPCDL相较于对比机制,时间开销更少,能够更精确地预测隐私预算.利用PPCDL可以合理地在轨迹数据中添加拉普拉斯噪声,有效地提高了轨迹数据的可用性.
