Abstract

In the present work, fabrication and optoelectronic application of nitrogen and silver codoped ZnO nanorod structure have been reported. The synthesized samples were used as photoanodes of dye-sensitized solar cell (DSSC). The as-prepared samples were characterized for structural, optical, morphological, and photovoltaic properties. The XRD spectra showed good crystallinity of all the samples. Optical study revealed the fact that doping has reduced the bandgap of the as-prepared samples. FESEM images confirmed the formation of nanorod structures with a diameter of ~50 nm. The efficiency of DSSC prepared by doped ZnO photoanodes has been increased up to 5.105% as compared with 0.707% for undoped/pure ZnO nanorod-based DSSC. This increase is due to reduced recombination of charge carriers and hence increased value of short-circuit current density caused by nitrogen and silver codoping.

氮和银共掺杂一维ZnO纳米结构，用于光电应用

抽象的

在当前工作中，已经报道了氮和银共掺杂的ZnO纳米棒结构的制造和光电应用。合成的样品用作染料敏化太阳能电池（DSSC）的光阳极。对所制备的样品进行结构，光学，形态和光伏性质的表征。XRD谱图显示所有样品的良好结晶度。光学研究表明，掺杂已降低了所制备样品的带隙这一事实。FESEM图像证实了直径约50 nm的纳米棒结构的形成。由掺杂的ZnO光电阳极制备的DSSC的效率已提高到5.105％，相比之下，未掺杂/纯的ZnO纳米棒基DSSC的效率为0.707％。
