TL;DR: In this paper, an active layer comprising a new widebandgap polymer donor named PBQx-TF and a new low-bandgap non-fullerene acceptor (NFA) named eC9-2Cl is rationally designed.
Journal ArticleDOI
Controlled Synthesis and Optical Properties of Colloidal Ternary Chalcogenide CuInS2 Nanocrystals
TL;DR: In this paper, a facile method for the synthesis of size and shape-controlled CuInS2 semiconductor nanocrystals was developed by thermolysis of a mixed solution of CuAc, In(Ac)3, and dodecanethiol in noncoordinating solvent 1-octadecene (ODE) at 240 °C.
Journal ArticleDOI
Fine-Tuned Photoactive and Interconnection Layers for Achieving over 13% Efficiency in a Fullerene-Free Tandem Organic Solar Cell
Yong Cui,Huifeng Yao,Bowei Gao,Yunpeng Qin,Shaoqing Zhang,Bei Yang,Chang He,Bowei Xu,Jianhui Hou +8 more
TL;DR: A new non-fullerene acceptor with an optical band gap (Egopt) of 1.68 eV is designed for the front subcells and the phase-separation morphology of a fullerene-free active layer is optimized to fabricate the rear subcell.
Journal ArticleDOI
Improved Charge Transport and Reduced Nonradiative Energy Loss Enable Over 16% Efficiency in Ternary Polymer Solar Cells
TL;DR: This work suggests that utilizing the complementary advantages of fullerene and NFAs is a promising way to finely tune the detailed photovoltaic parameters and further improve the PCEs of PSCs.
