| 1 | Three-dimensional artificial transpiration for efficient solar waste-water treatment显示文摘Solar steam generation is emerging as promising solar-energy conversion technology for potential applications in desalination, sterilization and chemical purification. Despite the recent use of photon management and thermal insulation, achieving optimum solar steam efficiency requires simultaneous minimization of radiation, convection and conduction losses without compromising light absorption.Inspired by the natural transpiration process in plants, here we report a 3 D artificial transpiration device with all three components of heat loss and angular dependence of light absorption minimized, which enables over 85% solar steam efficiency under one sun without external optical or thermal management. It is also demonstrated that this artificial transpiration device can provide a complementary path for waste-water treatment with a minimal carbon footprint, recycling valuable heavy metals and producing purified water directly from waste water contaminated with heavy metal ions. | Xiuqiang Li Renxing Lin George Ni Ning Xu Xiaozhen Hu Bin Zhu Guangxin Lv Jinlei Li Shining Zhu Jia Zhu | 2018 | National Science Review2018，5，1： | 27 |
| 2 | Low-temperature processed inorganic hole transport layer for efficient and stable mixed Pb-Sn low-bandgap perovskite solar cells显示文摘Metal halide perovskite solar cells(PSCs)have attracted tremendous attention as an emerging photovoltaic technology due to their high efficiency,low cost and ease of fabrication from earth-abundant materials[1,2].The power conversion efficiencies(PCEs)have been rapidly boosted from 3.8%in the pioneer’s work to a certified 24.2%nowadays in just ten years[3].The PCE breakthroughs in PSCs have mostly adopted full lead-based perovskites(APbX3)with bandgaps of 1.5–1.6 eV. | Qiaolei Han Ying Wei Renxing Lin Zhimin Fang Ke Xiao Xin Luo Shuai Gu Jia Zhu Liming Ding Hairen Tan | 2019 | Science Bulletin2019，64，19： | 13 |

| 4 | Simultaneously enhanced moisture tolerance and defect passivation of perovskite solar cells with cross-linked grain encapsulation显示文摘The grain surfaces(film surface and grain boundary)of polycrystalline perovskite films are vulnerable sites in solar cells since they pose a high defect density and initiate the degradation of perovskite absorber.Achieving simultaneously defect passivation and grain protection from moisture is crucial for the viability of perovskite solar cells.Here,an in situ cross-linked grain encapsulation(CLGE)strategy that improves both device stability and defect passivation is reported.Cross-linkable semiconducting small molecules are mixed into the antisolvent to uniformly form a compact and conducting cross-linked layer over the grain surfaces.This cross-linked coating layer not only passivates trap states and facilitates hole extraction,but also enhances the device stability by preventing moisture diffusion.Using the CLGE strategy,a high power conversion efficiency(PCE)of 22.7%is obtained in 1.55-eV bandgap planar perovskite solar cells.The unencapsulated devices with CLGE exhibit significantly enhanced device stability again moisture and maintain>90%of their initial PCE after shelf storage under ambient condition for over10,000 h. | Ke Xiao Qiaolei Han Yuan Gao Shuai Gu Xin Luo Renxing Lin Jia Zhu Jun Xu Hairen Tan | 2021 | Journal of Energy Chemistry2021，30，5： | 2 |
| 5 | Recent progress in developing efficient monolithic all-perovskite tandem solar cells显示文摘Organic–inorganic halide perovskites have received widespread attention thanks to their strong light absorption,long carrier diffusion lengths,tunable bandgaps,and low temperature processing.Single-junction perovskite solar cells(PSCs)have achieved a boost of the power conversion efficiency(PCE)from 3.8%to 25.2%in just a decade.With the continuous growth of PCE in single-junction PSCs,exploiting of monolithic all-perovskite tandem solar cells is now an important strategy to go beyond the efficiency available in single-junction PSCs.In this review,we first introduce the structure and operation mechanism of monolithic all-perovskite tandem solar cell.We then summarize recent progress in monolithic all-perovskite tandem solar cells from the perspectives of different structural units in the device:tunnel recombination junction,wide-bandgap top subcell,and narrow-bandgap bottom subcell.Finally,we provide our insights into the challenges and scientific issues remaining in this rapidly developing research field. | Yurui Wang Mei Zhang Ke Xiao Renxing Lin Xin Luo Qiaolei Han Hairen Tan | 2020 | Journal of Semiconductors2020，41，5： | 2 |
| 6 | Cross-linked hole transport layers for high-efficiency perovskite tandem solar cells显示文摘Perovskite tandem solar cells have recently received extensive attention due to their promise of achieving power conversion efficiency(PCE)beyond the limits of single-junction cells.However,their performance is still largely constrained by the widebandgap perovskite solar cells which show considerable open-circuit voltage(VOC)losses.Here,we increase the VOCand PCE of wide-bandgap perovskite solar cells by changing the hole transport layer(HTL)from commonly used poly(bis(4-phenyl)(2,4,6-trimethylphenyl)amine)(PTAA)to in-situ cross-linked small molecule N_(4),N_(4)′-di(naphthalen-1-yl)-N_(4),N_(4)′-bis(4-vinylphenyl)biphenyl-4,4′-diamine(VNPB).The stronger interaction and lower trap density at the VNPB/perovskite interface improve the PCE and stability of wide-bandgap perovskite solar cells.By using the cross-linked HTL for front wide-bandgap subcells,PCEs of 24.9%and 25.4%have been achieved in perovskite/perovskite and perovskite/silicon tandem solar cells,respectively.The results demonstrate that cross-linkable small molecules are promising for high-efficiency and cost-effective perovskite tandem photovoltaic devices. | Yurui Wang Shuai Gu Guoliang Liu Liping Zhang Zhou Liu Renxing Lin Ke Xiao Xin Luo Jianhua Shi Junling Du Fanying Meng Ludong Li Zhengxin Liu Hairen Tan | 2021 | Science China Chemistry2021，64，11： | 1 |
| 7 | Revealing the output power potential of bifacial monolithic all-perovskite tandem solar cells显示文摘Bifacial monolithic all-perovskite tandem solar cells have the promise of delivering higher output power density by inheriting the advantages of both tandem and bifacial architectures simultaneously.Herein,we demonstrate,for the first time,the bifacial monolithic all-perovskite tandem solar cells and reveal their output power potential.The bifacial tandems are realized by replacing the rear metal electrodes of monofacial tandems with transparent conduction oxide electrodes.Bandgap engineering is deployed to achieve current matching under various rear illumination conditions.The bifacial tandems show a high output power density of 28.51 mW cm−2 under a realistic rear illumination(30 mW cm−2).Further energy yield calculation shows substantial energy yield gain for bifacial tandems compared with the monofacial tandems under various ground albedo for different climatic conditions.This work provides a new device architecture for higher output power for all-perovskite tandem solar cells under real-world conditions. | Hongjiang Li Yurui Wang Han Gao Mei Zhang Renxing Lin Pu Wu Ke Xiao Hairen Tan | 2022 | eLight2022，2，1： | 0 |
