TL;DR: This work offers a simple and viable option of HTL modification to realize highly efficient OSCs by mixing WOx nanoparticles with a poly(3,4-ethylenedioxythiophene):polystyrene sulfonate emulsion, the surface free energy of the HTL is improved and the morphology of the active layer is optimized.
Journal ArticleDOI
Design of a New Fused-Ring Electron Acceptor with Excellent Compatibility to Wide-Bandgap Polymer Donors for High-Performance Organic Photovoltaics.
TL;DR: A new FREA is developed, ZITI, featuring an octacyclic dithienocyclopentaindenoindene central core, possessing an excellent compatibility with commercially available polymer donors and delivering very high power conversion efficiencies.
Journal ArticleDOI
Fine Multi-Phase Alignments in 2D Perovskite Solar Cells with Efficiency over 17% via Slow Post-Annealing.
Guangbao Wu,Xing Li,Jiyu Zhou,Jianqi Zhang,Xuning Zhang,Xuanye Leng,Peijun Wang,Ming Chen,Dongyang Zhang,Kui Zhao,Shengzhong Frank Liu,Huiqiong Zhou,Yuan Zhang +12 more
TL;DR: Investigation with optical spectroscopy coupled with structural analyses indicates that enhanced crystal orientation and favorable alignment on the multiple perovskite phases is obtained with SPA treatment, which promotes carrier transport/extraction and suppresses Shockley-Read-Hall charge recombination in the solar cell.
Journal ArticleDOI
Regulating Bulk-Heterojunction Molecular Orientations through Surface Free Energy Control of Hole-Transporting Layers for High-Performance Organic Solar Cells
Jianqiu Wang,Jianqiu Wang,Zhong Zheng,Dongyang Zhang,Jianqi Zhang,Jiyu Zhou,Jingchong Liu,Shenkun Xie,Yong Zhao,Yuan Zhang,Zhixiang Wei,Jianhui Hou,Zhiyong Tang,Huiqiong Zhou +13 more
TL;DR: Enhanced fill factor and power conversion efficiencies in both fullerene and nonfullerene OSCs are achieved, which is attributed to the increased charge carrier mobility and sweepout with reduced recombination.
Journal ArticleDOI
Fluorination with an enlarged dielectric constant prompts charge separation and reduces bimolecular recombination in non-fullerene organic solar cells with a high fill factor and efficiency > 13%
Xuning Zhang,Dongyang Zhang,Qian Zhou,Rong Wang,Jiyu Zhou,Jianqiu Wang,Huiqiong Zhou,Yuan Zhang +7 more
TL;DR: Based on the fluorinated PBDBT-2F donor and IT-4F acceptor with a favorably enhanced dielectric constant in the blend films, this article explored key factors attributing to the realized high fill factor (0.745) and efficiency (13.4%) in the solar cells.
