Effect of dye sensitization's temperature on ZnO-based solar cells
2021, Chemical Physics LettersSolution-method processed Bi-type nanoelectrode materials for supercapacitor applications: A review
2021, Renewable and Sustainable Energy ReviewsCharacterization of dye-sensitized solar cells based on various CaCO<inf>3</inf>-doped ZnO photoanodes prepared using wet powder mixing and grinding
2020, OptikCitation Excerpt :Wettability provides a simple and reliable method to comprehend surface engineering. Surface wettability research can be used as a diagnostic method to evaluate beforehand the quality/performance of ZnO-based DSSC [29] or to understand indirectly the dye loading capacity [28,30] or the electrolyte infiltration behavior [31] of a photoanode film without actual fabrication. The surface tension of droplets reflects the surface energy, and the surface energy is directly related to the surface properties.
Influence of Zn concentration and dye adsorption time on the photovoltaic performance of M-SILAR deposited ZnO-based dye sensitized solar cells
2016, Journal of Photochemistry and Photobiology A: ChemistryCitation Excerpt :However, further decrease in contact angle with increase in dye adsorption time is due to the surface aggregation effect. Due to dye aggregation, surface roughness increases leading to decrease in the contact angle value [37]. The Nyquist and Bode plots (Fig. 5(c and d)) help to better understand the effect of dye adsorption time on the electron transfer properties of DSSCs.
Photosensitization of ZnO nanowire-based electrodes using one-step hydrothermally synthesized CdSe/CdS (core/shell) sensitizer
2016, Solar EnergyCitation Excerpt :Decrease in Jsc for at 5th CdSe/CdS was due to increase in overall ZnO/(CdSe/CdS) series resistance (Shinde et al., 2013). Here, fill factor (ff, %) value dropped from 46% to 38% which was an indication of increased electrode series resistance due to increase of overall electrode thickness (Ambade et al., 2009; Shaikh et al., 2015). In conclusion, CdSe/CdS core/shell QDs were grown on ZnO nanowires to form ZnO/(CdSe/CdS) core/shell heterostructure using one-step hydrothermal method.
Band alignment of ZnO/ZnS heterojunction prepared through magnetron sputtering and measured by X-ray photoelectron spectroscopy
2015, VacuumCitation Excerpt :Recently, Gao and his coworkers prepared a four-layer ZnO NW arrays on TCOs with much higher specific surface area and demonstrated a power conversion efficiency of over 7% under a AM1.5 irradiation [9,10], which was the highest η value obtained in the ZnO related DSSCs up to now. Despite of those, it was still rather difficult to replace TiO2 by ZnO completely due to both the poor dye anchoring ability and stability [11,12]. It might be a good solution to enhance the activity and stability of a photocatalyst through constructing a semiconductor heterojunctions (HJ) or hybrid.
