摘要: Raman spectroscopy and photoluminescence (PL) were used to investigate the improved short-circuit current density (JSC) of CdS/CdSe quantum dot (QD)-sensitized solar cells with multi-walled carbon nanotubes (MWCNTs). Raman and PL experiments were carried out in order to explore the hot-electron and cold-electron injections, respectively. The experimental results showed that the concentration of MWCNTs influences the hot-electron and cold-electron injections from CdS/CdSe QDs to TiO2 nanoparticles. Therefore, the improved JSC in CdS/CdSe QD-sensitized solar cells can be explained as due to the better electron injections. 出版者: Elsevier B.V 出版日期: 2015-09-01 出處: Vibrational spectroscopy, 2015-09, Vol.80, p.66-69 版權: 2015 Elsevier B.V. 識別號: ISSN: 0924-2031 識別號: EISSN: 1873-3697 識別號: DOI: 10.1016/j.vibspec.2015.08.001
