“…Among the most studied types of Bi 2 S 3 solar cells, there are the thin film based devices, − but to a greater extent, the regenerative photoelectrochemical ones. − These photovoltaic devices have a relatively low efficiency, typically, less than 0.5%. The reports on types of Bi 2 S 3 solar cells do not explore the size effect of this material on the response as a light harvester.…”

This paper highlights the inconvenience of sodium ions in the Bi 2 S 3 quantum dots (QDs) deposition procedure, on the TiO 2 surface, for the conversion efficiency of the sensitized solar cells derived from these materials. Porous TiO 2 electrodes were sensitized with QDs obtained by the successive ion layer adsorption and reaction (SILAR) technique, using aqueous solutions of Bi(NO 3 ) 3 as the cation precursor and Na 2 S as the sulfide source. Independently, elemental sulfur vapor was used to replace the Na 2 S solution in the synthesis procedure. The obtained layers were characterized by X-ray diffraction, transmission electron microscopy, Raman scattering, and diffuse reflectance spectroscopy. We found that the presence of sodium ions in the reaction system strongly affects the formation of Bi 2 S 3 on the porous TiO 2 . This result contrasts with what other authors have claimed. Using elemental sulfur vapor as a precursor, crystalline Bi 2 S 3 nanoparticles are formed on the TiO 2 surface. The sensitized solar cells produced using the two different types of photoelectrodes were compared based on the photocurrent−voltage characteristic and the photocurrent time stability. The sensitized photoelectrodes derived from elemental sulfur vapor are much more stable over time and can achieve an efficiency of 0.84%. This is the highest conversion efficiency value for any Bi 2 S 3 photoelectrochemical cell.

“…Among the different studies on Bi 2 S 3-based solar cells, many reports are on the thin film-based solar cells (Wang et al 2007;Moreno-García et al 2011;Becerra et al 2011) and photoelectrochemical solar cells (PEC) (Bhattacharya and Pramanik 1982;Mane et al 2007;Rajalakshmi et al 2013;Narayanan et al 2013;Jana et al 2009;Rath et al 2011). These days, Bi 2 S 3 has received considerable attention as an absorber in photovoltaic applications (Kamat 2008).…”

This work deals with the sensitization of the porous TiO 2 films of thickness about 4 lm deposited on fluorine-doped tin oxide with nanocrystalline Bi 2 S 3 for photovoltaic application. The sensitization was achieved for four different sensitization times employing chemical solution deposition with bismuth nitrate and sodium thiosulphate as precursors for Bi 3? and S 2-, respectively. The unsensitized and sensitized photoelectrodes were characterized using X-ray diffractometry, scanning electron microscopy and diffused reflectance spectroscopy. XRD patterns show the signatures of both anatase TiO 2 and orthorhombic Bi 2 S 3 in the sensitized photoanodes. However, crystallinity of Bi 2 S 3 increased with increase in sensitization time from 10 to 40 min. The temporal effect of sensitization and annealing on the photovoltaic performance of the solar cells fabricated using four different photoelectrodes was studied using the photocurrent density versus photovoltage curves. Annealing apparently improved the photovoltaic performance of photoanodes. The best performance was obtained for cell fabricated using annealed TiO 2 /Bi 2 S 3 photoanode after 30 min sensitization time showing V oc * 0.37 mV, J sc * 0.52 mA/cm 2 , FF * 68 and 0.43 %.
