Inorganic solar cells, as durable photovoltaic devices for harvesting electric energy from sun light,have received tremendous attention due to the fear of exhausting the earth's energy resources and damaging the living environment due to greenhouse gases. Some recent developments in nanotechnology have opened up new avenues for more relevant inorganic solar cells produced by new photovoltaic conversion concepts and effective solar energy harvesting nanostructures. In this review, the multiple exciton generation effect solar cells, hot carrier solar cells, one dimensional material constructed asymmetrical schottky barrier arrays, noble nanoparticle induced plasmonic enhancement, and light trapping nanostructured semiconductor solar cells are highlighted.

针对目前基于p型硅片制备的单结太阳电池进一步提高表面钝化膜生产效率,利用氮化硅(SiNx)薄膜良好的钝化效果与价格低廉的二氧化钛(TiO2)膜,降低SiNx镀膜厚度减薄对少子寿命的影响。在单晶硅片表面先用PECVD法沉积SiNx薄膜,然后用热喷涂沉积TiO2薄膜。对比测试了热喷涂沉积TiO2薄膜前后电池的性能,结果表明在SiNx膜上增加TiO2膜层后少子寿命明显提高,这可能是TiO2膜结构内存在固定正电荷所致。这种双层结构封装后的太阳电池显示出了较好的光学与电学性能,对进一步改进太阳电池性能具有重要参考价值。

采用第一性原理和玻尔兹曼理论相结合的方法对最近合成的Zintl相化合物Ba3Sn3Sb4的晶体结构、电子结构、弹性性质和热电特性进行了研究.本文确定了合成Ba3Sn3Sb4时对各元素化学势的要求,计算的弹性常数和力学稳定判定标准表明Ba3Sn3Sb4具有力学稳定性.差分电荷密度显示Ba与Sn-Sb组成的网格[Sn3Sb4]^6-之间成离子键,网格内Sn-Sb之间为共价键,两键共存说明Ba3Sn3Sb4是典型的Zintl相化合物.能带结构的计算表明Ba3Sn3Sb4是带隙约为0.29 eV的间接带隙半导体,导带区域的多能谷特征有利于材料的热电特性.在电子结构的基础上,本文采用Bolzmann理论计算了Ba3Sn3Sb4的热电特性.由于纯相Ba3Sn3Sb4是n型半导体,p型掺杂的塞贝克系数在T=500和700 K时随载流子浓度增加从负值变为正值,而对应的ZT值从正值减小到零,再从零变到最大值0.09.n型掺杂Ba3Sn3Sb4时,由于热激发效应随温度增加而增强,少子对塞贝克系数的贡献增大,在T>500 K时展现出双极化效应;当载流子浓度为1.14×10^20cm^-3,温度为700 K时,最大ZT值为0.26,几乎是p型掺杂时的3倍.

目的:探讨cyclin D2和bcl-2在弥漫大B细胞淋巴瘤(DLBCL)中的表达及其意义。方法:收集2015年1月至2020年3月在保定市第一中心医院手术切除的87例DLBCL组织及23例淋巴组织反应性增生(RLH)患者组织,采用免疫组织化学法检测DLBCL和RLH组织中cyclin D2和bcl-2蛋白的表达情况,分析二者表达间的相互关系及与DLBCL患者临床病理特征的关系。结果:DLBCL和RLH中cyclin D2蛋白阳性率分别为33.3%(29/87)、2.0%(1/23),bcl-2蛋白阳性率分别为60.9%(54/87)、7.0%(3/23);DLBCL中cyclin D2、bcl-2蛋白阳性率均高于RLH,差异均有统计学意义(χ^(2)=7.566, P=0.006;χ^(2)=17.512, P0.05)。cyclin D2和bcl-2蛋白在DLBCL中的表达呈正相关( r=1.000, P<0.01)。结论:cyclin D2和bcl-2可能与DLBCL的发生、发展相关,两者可能有一定的协同作用。
