Journal ArticleDOI
Nanoscale localized contacts for high fill factors in polymer-passivated perovskite solar cells
Jun Peng,Daniel Walter,Yuhao Ren,Mike Tebyetekerwa,Yiliang Wu,Qiaoling Lin,Juntao Li,Teng Lu,Arafat Mahmud,Olivier Lee Cheong Lem,Shenyou Zhao,Wenzhu Liu,Yun Liu,Heping Shen,Li Li,Felipe Kremer,Hieu T. Nguyen,Duk-Yong Choi,Klaus Weber,Kylie R. Catchpole,Thomas P. White +20 more
TL;DR: A nanopatterned electron transport layer is introduced that overcomes this trade-off by modifying the spatial distribution of the passivation layer to form nanoscale localized charge transport pathways through an otherwise passivated interface, thereby providing both effective passivation and excellent charge extraction.
Journal ArticleDOI
Monolithic perovskite/silicon-homojunction tandem solar cell with over 22% efficiency
Yiliang Wu,Di Yan,Jun Peng,Yimao Wan,Sieu Pheng Phang,Heping Shen,Nandi Wu,Chog Barugkin,Xiao Fu,Sachin Surve,Dale Grant,Daniel Walter,Thomas P. White,Kylie R. Catchpole,Klaus Weber +14 more
TL;DR: In this paper, a mesoscopic perovskite top subcell and a high-temperature tolerant homojunction c-Si bottom subcell are used to increase the temperature tolerance of the bottom cell.
Journal ArticleDOI
Design, fabrication and characterisation of a 24.4% efficient interdigitated back contact solar cell
Evan Franklin,Kean Fong,Keith R. McIntosh,Andreas Fell,Andrew Blakers,Teng Kho,Daniel Walter,Da Wang,Ngwe Zin,Matthew Stocks,Er-Chien Wang,Nicholas E. Grant,Yimao Wan,Yang Yang,Xueling Zhang,Zhiqiang Feng,Pierre J. Verlinden +16 more
TL;DR: The interdigitated back contact (IBC) solar cells developed at the Australian National University have resulted in an independently confirmed (Fraunhofer Institut fur Solare Energiesysteme (ISE) CalLab) designated-area efficiency of 24.4 ± 0.7%, featuring short-circuit current density of 41.95 µm/cm2, open circuit voltage of 703 µmV and 82.7% fill factor as discussed by the authors.
Journal ArticleDOI
Double‐Sided Surface Passivation of 3D Perovskite Film for High‐Efficiency Mixed‐Dimensional Perovskite Solar Cells
Arafat Mahmud,Yanting Yin,Huyen Pham,Daniel Walter,Jun Peng,Yiliang Wu,Li Li,Heping Shen,Nandi Wu,Naeimeh Mozaffari,Gunther G. Andersson,Kylie R. Catchpole,Klaus Weber,Thomas P. White +13 more
TL;DR: The work was supported by the Australian Government through the Australian Renewable Energy Agency (ARENA) and the Australian Research Council (ARC), and T.P.W. as discussed by the authors was the recipient of a Future Fellowship (Project No. FT180100302).
Journal ArticleDOI
Identifying the Cause of Voltage and Fill Factor Losses in Perovskite Solar Cells by Using Luminescence Measurements
Nandi Wu,Yiliang Wu,Daniel Walter,Heping Shen,Dale Grant,Chog Barugkin,Xiao Fu,Jun Peng,Thomas P. White,Kylie R. Catchpole,Klaus Weber +10 more
TL;DR: It is demonstrated that luminescence-based measurements can be used to reconstruct cell I–V curves with removal of any transport limitation effects, which allows the contribution of recombination, shunt resistance, and series resistance on the fill factor to be clarified.
