A series of ternary organic photovoltaics(OPVs) are fabricated with one wide bandgap polymer D18-Cl as donor, and well compatible Y6 and Y6-1O as acceptor. The open-circuit-voltage(V)of ternary OPVs is monotonously increased along with the incorporation of Y6-1O, indicating that the alloy state should be formed between Y6 and Y6-1O due to their excellent compatibility. The energy loss can be minimized by incorporating Y6-1 O, leading to the VOC improvement of ternary OPVs. By finely adjusting the Y6-1O content, a power conversion efficiency of 17.91% is achieved in the optimal ternary OPVs with 30 wt% Y6-1O in acceptors, resulting from synchronously improved short-circuit-current density(JSC) of 25.87 mA cm, fill factor(FF) of 76.92% and VOC of 0.900 V in comparison with those of D18-Cl : Y6 binary OPVs. The JSC and FF improvement of ternary OPVs should be ascribed to comprehensively optimal photon harvesting, exciton dissociation and charge transport in ternary active layers. The more efficient charge separation and transport process in ternary active layers can be confirmed by the magnetophotocurrent and impedance spectroscopy experimental results, respectively. This work provides new insight into constructing highly efficient ternary OPVs with well compatible Y6 and its derivative as acceptor.

The vertical phase distribution of active layers plays a vital role in balancing exciton dissociation and cha rge transport for achieving efficient polymer solar cells(PSCs).The layer-by-layer(LbL)PSCs are commonly prepared by using sequential spin-coating method from donor and acceptor solutions with distinct solvents and solvent *** enhanced exciton dissociation is expected in the LbL PSCs with efficient charge transport in the relatively neat donor or acceptor *** this work,a series of LbL all-polymer solar cells(APSCs)were fabricated with PM6 as donor and PY-DT as acceptor,and triplet material m-Ir(CPmPB)_(3)is deliberately incorporated into PY-DT layer to prolong exciton lifetimes of active *** power conversion efficiency(PCE)of LbL APSCs is improved to 18.24%from 17.32%by incorporating 0.3 wt%m-Ir(CPMPB)_(3)in PY-DT layer,benefiting from the simultaneously enhanced short-circuit current density(Isc)of 25.17 mA cm^(-2)and fill factor(FF)of 74.70%.The enhancement of PCE is attributed to the efficient energy transfer of m-Ir(CPmPB)_(3)to PM6 and PY-DT,resulting in the prolonged exciton lifetime in the active layer and the increased exciton diffusion *** efficient energy transfer from m-Ir(CPmPB)_(3)to PM6 and PY-DT layer can be confirmed by the increased photoluminescence(PL)intensity and the prolonged PL lifetime of PM6 and PY-DT in PM6+m-Ir(CPmPB)_(3)and PY-DT+m-Ir(CPmPB)_(3)*** study indicates that the triplet material as solid additive has great potential in fabricating efficient LbL APSCs by prolonging exciton lifetimes in active layers.

A finite element model used to simulate the dynamics with continuum and discontinuum is presented. This new approach is conducted by constructing the general contact model. The conventional discrete element is treated as a standard finite element with one node in this new method. The one-node element has the same features as other finite elements, such as element stress and strain. Thus, a general finite element model that is consistent with the existed finite element model is set up. This new model is simple in mathematical concept and is straightforward to be combined into the existing standard finite element code. Numerical example demonstrates that this new approach is more effective to perform the dynamic process analysis in which the interactions among a large number of discrete bodies and continuum objects are included.

为探究季节性冰封浅湖热力学特征,于2010年10月至2013年7月对高原腹地一典型热融湖塘冰层生消、水/冰温及气象条件开展原位观测,分析了水温分布时间变化、温跃层以及冰生消对水温结构的影响。结果发现:冰面升华显著,贯穿整个冰期;水温日变化、季节变化和垂直结构受气温、大气辐射、风速、冰生消和湖底沉积层热贡献影响显著;在"无冰期—结冰前—冰生长期—冰融化期—融化后—无冰期"年循环过程中水温垂直结构分别呈现出"分层—翻转—逆温分层—逆温与正温共存—翻转—分层"的循环过程。分层期水温结构仅由上部混合层和温跃层构成,且偶因强风搅动而全湖翻转混合。可见,相比大中型湖泊,季节性冰封浅湖热力学结构差异显著。
