Journal ArticleDOI
Next-generation organic photovoltaics based on non-fullerene acceptors
TL;DR: In this article, the authors highlight recent progress on single-junction and tandem NFA solar cells and research directions to achieve even higher efficiencies of 15-20% using NFA-based organic photovoltaics are also proposed.
Journal ArticleDOI
Stability of organic solar cells: challenges and strategies
Pei Cheng,Xiaowei Zhan +1 more
TL;DR: The factors limiting the stability of OSCs are summarized, such as metastable morphology, diffusion of electrodes and buffer layers, oxygen and water, irradiation, heating and mechanical stress, and recent progress in strategies to increase the stability are surveyed.
Journal ArticleDOI
Enabling low voltage losses and high photocurrent in fullerene-free organic photovoltaics
Jun Yuan,Tianyi Huang,Pei Cheng,Yingping Zou,Huotian Zhang,Jonathan Lee Yang,Sheng-Yung Chang,Zhenzhen Zhang,Wenchao Huang,Rui Wang,Dong Meng,Feng Gao,Yang Yang +12 more
TL;DR: A facile synthetic strategy is reported, where optoelectronic properties are delicately tuned by the introduction of electron-deficient-core-based fused structure into non-fullerene acceptors to achieve both low voltage loss and high current density, leading to a certified high efficiency.
Journal ArticleDOI
A planar electron acceptor for efficient polymer solar cells
TL;DR: In this article, a planar acceptor IDT-2BR was designed and synthesized for polymer solar cells (PSCs) based on P3HT:IDT 2BR blended films gave power conversion efficiencies of up to 5.12%.
Journal ArticleDOI
A 3D star-shaped non-fullerene acceptor for solution-processed organic solar cells with a high open-circuit voltage of 1.18 V
TL;DR: A novel 3D star-shaped acceptor based on triphenylamine as a core and diketopyrrolopyrrole as arms was synthesized and exhibited excellent thermal stability, strong absorption, and very high open-circuit voltage in solution-processed organic solar cells based on P3HT:S(TPA-DPP).
