Abstract The trade‐off between the open‐circuit voltage ( V oc ) and short‐circuit current density J sc has become core of organic photovoltaic research, realizing minimum energy offsets that can guarantee effective charge generation is strongly desired for high‐performance systems. Herein, a ternary solar cell with power conversion efficiency over 18% using large‐bandgap polymer donor, PM6, small‐bandgap alloy acceptor containing two structurally similar nonfullerene acceptors (Y6 AQx‐3)...
The use of photovoltaic technologies has been regarded as a promising approach for converting solar energy to electricity and mitigating the crisis, among these, organic photovoltaics (OPVs) have attracted broad interest because their solution processability, flexibility, light weight, potential large-area processing. development OPV materials, especially electron acceptors, one focuses in recent years. Compared with fullerene derivates, n-type non-fullerene molecules some unique merits,...
Compared with the quick development of polymer solar cells, achieving high-efficiency small-molecule cells (SMSCs) remains highly challenging, as they are limited by lack matched materials and morphology control to a great extent. Herein, two small molecules, BSFTR Y6, which possess broad well absorption energy levels, applied in SMSCs. Morphology optimization sequential solvent vapor thermal annealing makes their blend films show proper crystallinity, balanced high mobilities, favorable...

Efficient cathode interfacial layer-free organic solar cells are achieved, which deliver a power conversion efficiency of 12.3%.
Star-shaped magnesium porphyrins with four diketopyrrolopyrrole units conjugated by ethynyl linkers work as electron donors for organic solar cells.
A wide-bandgap polymer donor based on benzo[1,2-<italic>d</italic>:4,5-<italic>d</italic>′]bisthiazole is designed and synthesized delivering a PCE of 11.08% with low energy loss 0.50 eV.
Organic solar cells based on new medium-bandgap small-molecule electron acceptors reach PCEs of 10.05% and 11.86% in single-junction tandem devices, respectively.
A new low-bandgap D–A type non-fullerene acceptor is designed and synthesized, which successfully applied in full-vacuum-deposited organic solar cells realizes a PCE of 0.86%.
Fusing oxygen heterocycles into an indacenodithiophenebithiophene core contributes to realizing low bandgap non-fullerene molecular acceptors with a power conversion efficiency exceeding 8%.
In this work, we report dual‐gate a‐Si:H TFTs using indium tin oxide (ITO) as top‐gate electrodes for achieving high‐refresh‐rate LCDs. The exhibit higher on‐currents than conventional by 24‐42% depending on the width of top ITO gate passivation layer, which can significantly improve charging rate and picture quality LCDs with a refresh above 240 Hz. However, off‐current deteriorates increase is bad image stick leading to flickering issues. For channel length 5.2 µm, 2.5 µm would be optimal...
