| 1 | Viscosity and aggregation structure of nanocolloidal dispersions显示文摘In this work,the effects of nanoparticle size,particle volume fraction and pH on the viscosity of silicon dioxide nanocolloidal dispersions are investigated.Both size and pH are found to significantly affect nanocolloid viscosity.Two models are used to study the effect of aggregate structure on the viscosity of the nanocolloidal dispersion.The fractal concept is introduced to describe the irregular and dynamic aggregate structure.The structure of aggregates,which is considered to play an important role in viscosity,is affected by both intermolecular and electrostatic forces.The particle interaction is primarily affected by particle distance and becomes stronger with decreasing particle size and increasing volume fraction.The aggregate structure is also affected by the pH of the solution.Studying the relationship between pH and zeta-potential shows that with the neutralization of charges on the particle surface and decreasing electrical repulsion force,the particle interaction becomes dominated by attractive forces and the aggregates form a more compact structure. | WANG Tao NI MingJiang LUO ZhongYang SHOU ChunHui CEN KeFa | 2012 | Chinese Science Bulletin2012，57，27： | 4 |

| 3 | Efficiency-loss analysis of monolithic perovskite/silicon tandem solar cells by identifying the patterns of a dual two-diode model’s current-voltage curves显示文摘In this work,we developed a simple and direct circuit model with a dual two-diode model that can be solved by a SPICE numerical simulation to comprehensively describe the monolithic perovskite/crystalline silicon(PVS/c-Si)tandem solar cells.We are able to reveal the effects of different efficiency-loss mechanisms based on the illuminated current density-voltage(J-V),semi-log dark J-V,and local ideality factor(m-V)curves.The effects of the individual efficiency-loss mechanism on the tandem cell’s efficiency are discussed,including the exp(V/VT)and exp(V/2VT)recombination,the whole cell’s and subcell’s shunts,and the Ohmic-contact or Schottky-contact of the intermediate junction.We can also fit a practical J-V curve and find a specific group of parameters by the trial-and-error method.Although the fitted parameters are not a unique solution,they are valuable clues for identifying the efficiency loss with the aid of the cell’s structure and experimental processes.This method can also serve as an open platform for analyzing other tandem solar cells by substituting the corresponding circuit models.In summary,we developed a simple and effective methodology to diagnose the efficiency-loss source of a monolithic PVS/c-Si tandem cell,which is helpful to researchers who wish to adopt the proper approaches to improve their solar cells. | Yuheng Zeng Zetao Ding Zunke Liu Wei Liu Mingdun Liao Xi Yang Zhiqin Ying Jingsong Sun Jiang Sheng Baojie Yan Haiyan He Chunhui Shou Zhenhai Yang Jichun Ye | 2023 | Journal of Semiconductors2023，44，8： | 0 |
