One-dimensional ribbons and intrinsically benign grain boundaries promise antimony selenide (Sb2Se3) an appealing light absorber for photovoltaic applications.However,this peculiar property shows brilliance only when favorably oriented.Thus,a facile and straightforward method to control Sb2Se3 0rientation is in urgent requirement.

Apart from the geometrical morphology of nanocrystals (NCs),the surface chemistry has also shown significant effects on the physical and chemical properties of NCs.Colloidal quantum dots (QDs) are gen
我们采用高温热注入法合成高质量CIS量子点,并应用到量子点敏化电池中[1].通过调控Cu/In原子比合成不同组成的CIS量子点,研究发现:随着In含量的增加,量子点带隙变宽,吸光变窄,主要由于In含量的增加会降低价带的位置[2].另一方面,随着In含量的增加,荧光发射谱峰位会有所蓝移,荧光强度增加,前者归根于带隙变宽,后者是因为In含量增加会有戏效的减少量子点的缺陷,尤其是表面缺陷[3].
基于柔性衬底的铜锌锡硫硒(Cu2ZnSn(SxSe1-x)4,CZTSSe)薄膜太阳电池具有柔软、轻薄、安全、环保、高比功率等优点,显示了广阔的商业化应用前景.本文选取了强碱KOH、弱酸强碱盐K2CO3、有机酸盐CH3COOH和强酸强碱盐KC1作为掺入的K源,选择了不同的掺杂浓度进行研究,通过对薄膜物相、成分、形貌等的分析,发现对于不同的K源,1.0%都是最佳的掺杂量,同时研究了不同K源对CZTS
Au、Ag 具有很强的局域表面等离子共振效应(LSPR)且在可见光范围内具有优异的电磁增强效应[1,2].与Au 纳米材料相比,Ag 纳米材料还能表现出更高的太阳能转换效率及超灵敏的折射作用[3].此外,科研者还试图将Au 和Ag 整合到一个体系中,并将其应用于催化、传感、成像和生物医学等研究领域[4].
