在新冠疫情引发的劳动力争夺大战过后,美国经济出现了逆转的迹象。咨询机构查林杰一格雷-克里斯马斯公司(Challenger,Gray&Christmas Inc.)的数据显示,2022年美国雇主宣布裁员的人数比2021年增加了13%。这个裁员幅度并不大,仅次于2021年,也就是该公司从1993年追踪数据以来全年裁员人数最少的一年。尽管如此,就业市场有任何收紧的动作,都会开始使天平向雇主倾斜,对加强员工权力的短暂时期造成威胁,而正是这个时期产生了“职场躺平”、“大离职潮”等概念,以及新一代可能会在爱达荷州露营车里度过职业生涯的专业人士。

新调查评估了城市的宜居性、工作强度和社会保障服务等工作生活平衡得最好的城市:奥斯陆。最超负荷工作的城市?迪拜。这是移动接入技术公司Kisi在5月25日发布的一项调查给出的答案。调查考察了工作强度、城市宜居性、医疗服务质量、生活成本的可负担性以及假期是否充足等因素。例如在赫尔辛基(工作生活平衡排行榜上位居第三),一个标准上班族每年的带薪假有整整一个月,而洛杉矶的上班族只有一周。对很多人来说,疫情提供了一个重新思考人生重点、做出重大调整的时机——比如搬到一个新城市。随着劳动力市场的持续升温,各行各业的返岗计划都遇到了麻烦。

Since 1986,the donor-acceptor (D:A) heterojunction has been regarded a necessity for high-efficiency organic photovoltaics (OPVs),due to its unique advantage in compensating the intrinsic limitations of organic semiconductors,such as high exciton binding energy and poor ambipolar charge mobility. While this adversely causes tremendous non-radiative charge recombination and instability issues,which currently become the most critical limits for commercialization of OPVs. Here,we present a concept-to-proof study on the potential of D:A heterojunction free OPV by taking advantage of recent progress of non-fullerene acceptors. First,we demonstrate that the “free carriers” can be spontaneously generated upon illumination in an NFA,i.e.,the 6TIC-4F single layer. Second,the 6TIC-4F layer also exhibits good ambipolar charge transporting property. These exceptional characteristics distinguish it from the traditional organic semiconductors,and relieve it from the reliance of D:A heterojunction to independently work as active layer. As a result,the subsequent OPV by simply sandwiching the 6TIC-4F layer between the cathode and anode yields a considerably high power conversion efficiency ~1%. Moreover,we find the D:A heterojunction free device exhibits two order of magnitude higher electroluminescence quantum efficiency and significantly reduced VOC loss by 0.16 eV compared to those of the D:A BHJ structure,validating its promise for higher efficiency in the future. Therefore,our work demonstrates the possibility of using D:A heterojunction-free device structure for high performance,that can potentially become the next game changer of OPV.
