Journal ArticleDOI
Interface engineering of highly efficient perovskite solar cells
Huanping Zhou,Qi Chen,Gang Li,Song Luo,Tze Bing Song,Hsin Sheng Duan,Ziruo Hong,Jingbi You,Yongsheng Liu,Yang Yang +9 more
TL;DR: Perovskite films received a boost in photovoltaic efficiency through controlled formation of charge-generating films and improved current transfer to the electrodes and low-temperature processing steps allowed the use of materials that draw current out of the perovskites layer more efficiently.
Journal ArticleDOI
Planar Heterojunction Perovskite Solar Cells via Vapor-Assisted Solution Process
Qi Chen,Huanping Zhou,Ziruo Hong,Song Luo,Hsin Sheng Duan,Hsin-Hua Wang,Yongsheng Liu,Gang Li,Yang Yang +8 more
TL;DR: A low-temperature vapor-assisted solution process is demonstrated to construct polycrystalline perovskite thin films with full surface coverage, small surface roughness, and grain size up to microscale, paving the way for high reproducibility of films and devices.
Journal ArticleDOI
Improved air stability of perovskite solar cells via solution-processed metal oxide transport layers
Jingbi You,Lei Meng,Tze-Bin Song,Tzung-Fang Guo,Yang Yang,Wei-Hsuan Chang,Ziruo Hong,Huajun Chen,Huanping Zhou,Qi Chen,Yongsheng Liu,Nicholas De Marco +11 more
TL;DR: A solution-processed lead halide perovskite solar cell that has p-type NiO(x) and n-type ZnO nanoparticles as hole and electron transport layers, respectively, and shows improved stability against water and oxygen degradation when compared with devices with organic charge transport layers is reported.
Journal ArticleDOI
Low-Temperature Solution-Processed Perovskite Solar Cells with High Efficiency and Flexibility
Jingbi You,Ziruo Hong,Yang Yang,Qi Chen,Min Cai,Tze-Bin Song,Chun-Chao Chen,Shirong Lu,Yongsheng Liu,Huanping Zhou +9 more
TL;DR: A low-temperature processing technique is adopted to attain high-efficiency devices in both rigid and flexible substrates, using device structure substrate/ITO/PEDOT:PSS/CH(3)NH( 3)PbI(3-x)Cl(x)/PCBM/Al, where PEDOT?:PSS and PCBM are used as hole and electron transport layers, respectively.
Journal ArticleDOI
Controllable self-induced passivation of hybrid lead iodide perovskites toward high performance solar cells.
Qi Chen,Huanping Zhou,Tze-Bin Song,Song Luo,Ziruo Hong,Hsin-Sheng Duan,Letian Dou,Yongsheng Liu,Yang Yang +8 more
TL;DR: This controllable self-induced passivation technique for perovskite films is demonstrated, which enables their compositional change, and allows substantial enhancement in corresponding device performance.
