Toward Antimony Selenide Sensitized Solar Cells: Efficient Charge Photogeneration at spiro-OMeTAD/Sb2Se3/Metal Oxide Heterojunctions

Abstract: Photovoltaic devices comprising metal chalcogenide nanocrystals as light-harvesting components are emerging as a promising power-generation technology. Here, we report a strategy to evenly deposit Sb2Se3 nanoparticles on mesoporous TiO2 as confirmed by Raman spectroscopy, energy-dispersive X-ray spectrometry, and transmission electron microscopy. Detailed study of the interfacial charge transfer dynamics by means of transient absorption spectroscopy provides evidence of electron injection across the Sb2Se3/TiO… Show more

“…Bhattacharya and P. Pramanik determined the photoelectrochemical behavior of CBD‐Sb 2 Se 3 thin film in aqueous solution. In 2012, Guijarro et al observed efficient charge separation between SILAR grown Sb 2 Se 3 nanoparticles and mesoporous TiO 2 in the sensitized solar cells. However, no photovoltaic performance was reported in a complete device in their research.…”

“…Transient absorption spectroscopy is a pumpprobe technique that can be used to identify photogenerated charge separated states and monitor their decay dynamics. [22][23][24][25] Full experimental details of our transient absorption spectrometer have been described previously and are provided in the Supplementary Information to this manuscript. [ 26 ] Briefl y, transient absorption data were obtained using an optical pumpprobe set-up employing nitrogen-pumped dye-laser (600 ps pulse duration) as an excitation source and a tungsten lamp as a probe source.…”

“…Group V-VI binary pnictogen chalcogenide semiconductors, typically crystallizing into a one-dimensional nanostructure in layer-structures parallel to the growth direction, have attracted a lot of attention owing to their specific properties and potential application in various fields, namely, photovoltaic, thermoelectric, and electric devices123456. In particular, antimony selenide (Sb 2 Se 3 ) has promising characteristics, such as narrow band gap (approximately 1 eV), high chemical stability, and high Seebeck coefficient (1800 μVK −1 ).…”
