3Low-Temperature and Surfactant-Free Synthesis of Mesoporous TiO_2 Sub-Micron Spheres for Efficient Dye-Sensitized Solar Cells显示文摘Dye-sensitized solar cells(DSSCs) are one of the most promising next-generation solar cells due to their advantages over other counterparts. The photoanode of DSSCs has a great effect on the photovoltaic performance. Traditional photoanode includes a bottom nanoparticle layer and an upper scattering layer for better light capture in longer wavelength. Mesoporous nanostructures with size comparable to the wavelength of visible light are considered to be excellent light scattering centers by providing extra places for dye loading. Developing a green synthetic method is of great importance. Herein we report a facile and surfactant-free synthesis of mesoporous rutile TiO_2 submicrometer-sized spheres at temperature as low as 70°C. DSSCs based on photoanodes with an upper scattering layer composed of as-obtained mesoporous spheres on nanoparticle dense layer demonstrate an 18.0% improvement of power conversion efficiency. This simple approach may offer an energy-efficient and environmentally friendly alternative for DSSCs fabrication.Kaimo Deng Liang Li 2016Journal of Materials Science & Technology2016,32,1:0
4Stable one dimensional(1D)/three dimensional(3D)perovskite solar cell with an efficiency exceeding 23%显示文摘The interface properties of organic–inorganic mixed halide perovskite solar cells play a significant role in their photovoltaic performance.Defect states at the interface can decrease the power conversion efficiency through defect-assisted charge recombination and degrade the long-term stability.Low-dimensional perovskites exhibit excellent stabilities.They can be combined with three dimensional(3D)perovskites to utilize their advantages for fabrication of highperformance devices.In this study,we successfully construct a robust interface for perovskite films through mixed-dimensional engineering.After the introduction of a one dimensional(1D)-structured capping layer on the 3D perovskite through post-treatment,the number of defect states in the perovskite film is significantly decreased,while the lifetime of the photocarriers is increased.In addition,the 1D capping layer can serve as a diffusion barrier to reduce the ion migration and protect the vulnerable 3D perovskite against moisture.Perovskite solar cells based on stacked 1D/3D structures exhibit a power conversion efficiency of 23.3%and maintain 80%of the initial efficiency after storage for over 800 h under ambient conditions with a humidity of 50%.Their performances are superior to those of the 3D devices.This study provides a simple approach to simultaneously enhance the efficiency and stability of perovskite solar cells and may guide the development of other solar cells.Qinghua Chen Kaimo Deng Ying Shen Liang Li 2022InfoMat2022,4,5:0
