Yu Cao, Xinyun Zhu, Xingyu Tong, Jing Zhou, Jian Ni, Jianjun Zhang, Jinbo Pang

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 6,   Pages 997-1005 doi: 10.1007/s11705-019-1906-0

Abstract: Thin film solar cells have been proved the next generation photovoltaic devices due to their low cost, less material consumption and easy mass production. Among them, micro-crystalline Si and Ge based thin film solar cells have advantages of high efficiency and ultrathin absorber layers. Yet individual junction devices are limited in photoelectric conversion efficiency because of the restricted solar spectrum range for its specific absorber. In this work, we designed and simulated a multi-junction solar cell with its four sub-cells selectively absorbing the full solar spectrum including the ultraviolet, green, red as well as near infrared range, respectively. By tuning the Ge content, the record efficiency of 24.80% has been realized with the typical quadruple junction structure of a-Si:H/a-Si Ge :H/µc-Si:H/µc-Si Ge :H. To further reduce the material cost, thickness dependent device performances have been conducted. It can be found that the design of total thickness of 4 m is the optimal device design in balancing the thickness and the . While the design of ultrathin quadruple junction device with total thickness of 2 m is the optimized device design regarding cost and long-term stability with a little bit more reduction in . These results indicated that our solar cells combine the advantages of low cost and high stability. Our work may provide a general guidance rule of utilizing the full solar spectrum for developing high efficiency and ultrathin multi-junction solar cells.

Thermodynamic study on dynamic water and organic vapor sorption on amorphous valnemulin hydrochloride

Jinbo OUYANG, Jingkang WANG, Yongli WANG, Qiuxiang YIN, Hongxun HAO

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 1,   Pages 94-104 doi: 10.1007/s11705-015-1460-3

Abstract: The sorption of water and organic vapors on valnemulin hydrochloride was determined by dynamic vapor sorption at 25 °C. The adsorption-desorption behavior of water vapor and a series of organic vapors was investigated to probe the structural changes in valnemulin hydrochloride before and after sorption. The isothermal adsorption equilibrium data was evaluated using Guggenheim-Anderson-deBoer (GAB) and Brunauer-Emmett-Teller (BET) models. The BET model is applicable only at low relative pressures (0.1≤RP≤0.4) while the GAB model is applicable in the whole range of RPs (0.1≤RP≤0.9). The sorption kinetics at high RPs was determined by fitting the sorption data to the Avrami equation and the sorption content time relationship could be predicted by the Avrami equation. Finally, the possible sorption mechanism of valnemulin hydrochloride was also discussed.
