Journal ArticleDOI
Rational molecular design and supramolecular assembly of highly efficient organic electro-optic materials
TL;DR: In this article, the authors highlight the areas of special significance in recent organic electro-optic (EO) materials development and highlight the important issues relating to applications and prospects of these advanced EO materials.
Journal ArticleDOI
Multifunctional phosphonic acid self-assembled monolayers on metal oxides as dielectrics, interface modification layers and semiconductors for low-voltage high-performance organic field-effect transistors
TL;DR: The combination of excellent dielectric and interfacial properties results in high-performance OFETs with low-subthreshold slopes down to 75 mV dec(-1), high I(on)/I(off) ratios of 10(5)-10(7), contact resistance down to 700 Ω cm, and general applicability to solution-processed and vacuum-deposited n-type and p-type organic and polymer semiconductors.
Journal ArticleDOI

TL;DR: In this paper, two ternary non-fullerene polymer solar cells (NF PSCs) with high power conversion efficiency (PCE) up to 13.52% and 12.70% were demonstrated by adding a strongly aggregating polymer P1 into the classic PBDB-T:IT-M and PBDB T:ITIC non-functionalized blends.
Journal ArticleDOI
Ag-Incorporated Organic–Inorganic Perovskite Films and Planar Heterojunction Solar Cells
Qi Chen,Qi Chen,Lei Chen,Fengye Ye,Ting Zhao,Feng Tang,Adharsh Rajagopal,Zheng Jiang,Shenlong Jiang,Alex K.-Y. Jen,Yi Xie,Jinhua Cai,Liwei Chen +12 more
TL;DR: This work implies that Ag incorporation is a feasible route to adjust carrier concentrations in solution-processed perovskite materials in spite of the high concentration of intrinsic defects.
