ABSTRACT
A bi-layer photoanode for dye-sensitized solar cell (DSSC) was fabricated, in which TiO hollow spheres (THSs) were designed as a scattering layer and P25/multi-walled carbon nanotubes (MWNTs) as an under-layer. The THSs were synthesized by a sacrifice template method and showed good light scattering ability as an over-layer of the photoanode. MWNTs were mixed with P25 to form an under-layer of the photoanode to improve the electron transmission ability of the photoanode. The power conversion efficiency of this kind of DSSC with bi-layer was enhanced to 5.13 %, which is 14.25 % higher than that of pure P25 DSSC.
GRAPHICAL ABSTRACT
A bi-layer composite photoanode based on P25/MWNTs-THSs with improved light scattering and electron transmission, which will provide a new insight into fabrication and structure design of highly efficient dye-sensitized solar cells.
摘要
制备了一种用于染料敏化太阳能电池（DSSC）的双层光阳极，其中TiO空心球（THS）被设计为散射层，P25/多壁碳纳米管（MWNT）作为底层。通过牺牲模板法合成了THS，作为光阳极的上层显示出良好的光散射能力。将MWNT与P25混合形成光阳极的底层，以提高光阳极的电子传输能力。这种双层DSSC的功率转换效率提高到了5.13%，比纯P25 DSSC高14.25%。
