人体内存在着白色脂肪组织(white adipose tissue,WAT)、棕色脂肪组织(brown adipose tissue,BAT)和米色脂肪组织.WAT具有储能的作用,过量积聚可导致肥胖;棕色和米色脂肪为产热脂肪,具有潜在的抗肥胖作用[1].BAT能够通过利用葡萄糖和脂类产热,减少它们在循环中的过度沉积,起到预防肥胖性疾病和代谢异常的作用[2].BAT的产热过程受交感神经支配,且与解偶联蛋白1(uncoupling protein-1,UCP-1)的表达有关.UCP-1位于线粒体内膜中,是棕色脂肪细胞的标志性蛋白,它可以使H+从线粒体内膜渗漏到线粒体基质中,阻止二磷酸腺苷(adenosine diphosphate,ADP)磷酸化形成三磷酸腺苷(adenosine triphosphate,ATP),将能量以热能的形式散失[3].除产热外,BAT还能以多种形式释放不同的细胞因子(即棕色脂肪细胞因子,brown adipocytokines,batokines),调节机体的多种代谢过程.

栅极系统是离子推力器的主要组件,其透过率特性对推力器的效率和推力具有重要影响.为了进一步优化栅极性能和有效评估离子推力器效率,对离子推力器栅极透过率径向分布进行研究.采用particle-In-CellMonte Carlo Collision数值仿真方法对束流引出过程进行了模拟.分析了屏栅、加速栅以及栅极系统的透过率随栅孔引出束流离子数量的变化关系,结合放电室出口离子密度分布,进而分别得到屏栅透过率、加速栅透过率和栅极系统透过率的径向分布特性,最后进行实验验证.研究结果表明:屏栅透过率径向分布具有中心对称性,在推力器中心有最小值,从中心沿着径向逐渐增大;加速栅透过率径向分布与屏栅透过率变化趋势相反;栅极系统透过率受加速栅透过率的影响很小,其径向分布与屏栅透过率径向分布相近;离子推力器栅极总透过率随着束流增大而缓慢减小.研究结果可为离子推力器栅极优化提供参考.

16.48% Efficient solution-processed CIGS solar cells with crystal growth and defects engineering enabled by Ag doping strategy

引用

Journal of Energy Chemistry 2025年第1期100卷 59-65页

作者： Mengyu Xu Shaocong yan Ting Liang jia jia Shengjie Yuan Dongxing Kou Zhengji Zhou Wenhui Zhou Yafang Qi Yuena Meng Litao Han Sixin Wu Key Laboratory for Special Functional Materials of MOE National & Local Joint Engineering Research Centre for High-efficiency Display and Lighting Technology School of Nanoscience and Materials Engineering Henan University

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.
