Deying Luo,Wenqiang Yang,Zhiping Wang,Aditya Sadhanala,Qin Hu,Rui Su,Ravichandran Shivanna,Gustavo F. Trindade,John F. Watts,Zhaojian Xu,Tanghao Liu,Ke Chen,Fengjun Ye,Pan Wu,Lichen Zhao,Jiang Wu,Yongguang Tu,Yifei Zhang,Xiao-Yu Yang,Wei Zhang,Richard H. Friend,Qihuang Gong,Qihuang Gong,Henry J. Snaith,Rui Zhu,Rui Zhu +25 more
TL;DR: This approach produces a wider bandgap top layer and a more n-type perovskite film, which mitigates nonradiative recombination, leading to an increase in Voc by up to 100 millivolts, which led to a stabilized power output approaching 21% at the maximum power point.
Journal ArticleDOI
Charge-carrier balance for highly efficient inverted planar heterojunction perovskite solar cells
Ke Chen,Qin Hu,Qin Hu,Tanghao Liu,Lichen Zhao,Deying Luo,Jiang Wu,Yifei Zhang,Wei Zhang,Feng Liu,Feng Liu,Thomas P. Russell,Thomas P. Russell,Rui Zhu,Rui Zhu,Qihuang Gong,Qihuang Gong +16 more
TL;DR: The charge carrier balance strategy by interface engineering was employed to optimize carrier transport in the planar heterojunction perovskite solar cells, leading to high power conversion efficiency and stabilized output efficiency.
Journal ArticleDOI
High‐Performance Inverted Planar Heterojunction Perovskite Solar Cells Based on Lead Acetate Precursor with Efficiency Exceeding 18%
Lichen Zhao,Deying Luo,Jiang Wu,Qin Hu,Qin Hu,Wei Zhang,Wei Zhang,Ke Chen,Tanghao Liu,Yi Liu,Yifei Zhang,Feng Liu,Thomas P. Russell,Thomas P. Russell,Henry J. Snaith,Rui Zhu,Rui Zhu,Qihuang Gong,Qihuang Gong +18 more
TL;DR: In this article, a strategy to improve the efficiency for the perovskite solar cell based on lead acetate precursor was proposed. But the pervskite cells were not shown to achieve a high power conversion efficiency.
Journal ArticleDOI
