Subtle Balance Between Length Scale of Phase Separation and Domain Purification in Small‐Molecule Bulk‐Heterojunction Blends under Solvent Vapor Treatment

Advanced Materials (2015)

Miaomiao Li Feng Liu Xiangjian Wan Wang Ni Bin Kan

A series of solvents with different solubilities for DR3TBDTT and PC71 BM, and different boiling points, is used for solvent vapor annealing (SVA) treatment to systematically investigate the solvent-morphology-performance relationship. The presence of solvent molecules inside bulk-heterojunction (BHJ) thin films promotes the mobility of both donor and acceptor molecules, leading to crystallization and aggregation, which are important in modulating morphology.

A Cathode Interface Layer Based on 4,5,9,10‐Pyrene Diimide for Highly Efficient Binary Organic Solar Cells

Angewandte Chemie (2022)

Wenjing Sun Yating Wang Yamin Zhang Bing Sun Zeqi Zhang

Abstract Efficient cathode interfacial layers (CILs) are becoming essential elements for organic solar cells (OSCs). However, the absorption of commonly used cathode interfacial materials (CIMs) is either too weak or overlaps too much with that of photoactive materials, hindering their contribution to the light absorption. In this work, we demonstrate the construction of highly efficient CIMs based on 2,7‐di‐ tert ‐butyl‐4,5,9,10‐pyrene diimide (t‐PyDI) framework. By introducing amino, amino N‐oxide and quaternary ammonium bromide as functional groups, three novel self‐doped CIMs named t‐PyDIN, t‐PyDINO and t‐PyDINBr are synthesized. These CIMs are capable of boosting the device performances by broadening the absorption, forming ohmic contact at the interface of active layer and electrode, as well as facilitating electron collection. Notably, the device based on t‐PyDIN achieved a power conversion efficiency of 18.25 %, which is among the top efficiencies reported to date in binary OSCs.

Organic and solution-processed tandem solar cells with 17.3% efficiency

Science (2018)

Lingxian Meng Yamin Zhang Xiangjian Wan Chenxi Li Xin Zhang

Although organic photovoltaic (OPV) cells have many advantages, their performance still lags far behind that of other photovoltaic platforms. A fundamental reason for their low performance is the low charge mobility of organic materials, leading to a limit on the active-layer thickness and efficient light absorption. In this work, guided by a semi-empirical model analysis and using the tandem cell strategy to overcome such issues, and taking advantage of the high diversity and easily tunable band structure of organic materials, a record and certified 17.29% power conversion efficiency for a two-terminal monolithic solution-processed tandem OPV is achieved.

The Current Situation and Influencing Factors of Adversity Quotient of Medical Undergraduates

Research Square (Research Square) (2023)

Xinglei Wang Yihan Zhou Li Ma Ting Ma Yingqiao Wang

Abstract Aims: This study aims to investigate the current situation and related factors of adversity quotient of medical undergraduates. Design: Cross sectional. All participants completed a questionnaire voluntarily and anonymously. Methods: A cross-sectional design was adopted in this study, and medical undergraduates from a university in Lanzhou were selected as convenient samples (n=359). In addition to the socio-demographic questions, the Chinese version of Adversity Response Profile, Professional Identity Questionnaire, college student Professional Adaptability Scale and Coping Style Questionnaire were used to evaluate the characteristics of medical students. Results: The average stress quotient score was 190.91 (SD: 19.74).Multiple linear regression analysis showed that gender (β= -0.119, P=0.015) and professional adaptability (β= 0.379, P＜0.001) were related factors of adversity quotient, which might explain 18.5% of the total variation (F = 12.591, P<0.001). Conclusion: The adversity quotient level of medical undergraduates still has a large space for improvement.Gender and professional adaptability are related factors of adversity quotient. Impact: Adversity quotient is an important ability for medical undergraduates to face setbacks and challenges. Therefore, it is necessary to develop targeted interventions to improve adversity quotient.
