Semi-Locked Tetrathienylethene as a Building Block for Hole-Transporting Materials: Toward Efficient and Stable Perovskite Solar Cells
Chao Shen,Yongzhen Wu,Hao Zhang,Erpeng Li,Weiwei Zhang,Xiaojia Xu,Wenjun Wu,He Tian,Weihong Zhu +8 more
TL;DR: A semi-locked tetrathienylethene (TTE) serves as a promising building block for HTMs by fine-tuning molecular planarity, and represents the first hybrid orthogonal and planar conformation, thus leading to the desirable electronic and morphological properties in perovskite solar cells (PSCs).
Journal ArticleDOI

TL;DR: In this paper, a comprehensive control of voltage loss in excitonic type solar cells through efficacious engineering of the sensitizer and redox mediator is reported, making a breakthrough in the power conversion efficiency of dye-sensitized solar cells.
Journal ArticleDOI
Low cost and stable quinoxaline-based hole-transporting materials with a D–A–D molecular configuration for efficient perovskite solar cells
TL;DR: Molecular hole-transporting materials containing a weak electron acceptor core can simultaneously improve the stability and photovoltaic performance of perovskite solar cells.
Journal ArticleDOI
Unprecedentedly targeted customization of molecular energy levels with auxiliary-groups in organic solar cell sensitizers
TL;DR: Lowering the LUMOs and decreasing energy “waste” is targeted through inserting an auxiliary group from an electron donor or acceptor into D–π–A organic sensitizers, and the photovoltaic efficiency increases 38 fold.
