“…It is apparent that the highest photocurrent was obtained in the case of individual DSSC sensitized with Dye 3 for both DSSCs based on TiO 2 and Z n O. It is also abundant that photocurrent value depends on the binding affinity, and previous studies suggest that the amounts of adsorbed organic dyes are sometimes different under the same concentration and thickness of TiO 2 or Z n O film (Wang et al , 2015; Yu et al , 2016).…”

Purpose The purpose of this paper is to study the substituent effect in dye-sensitized solar cells’ (DSSCs) performance. For this end, three new metal organic dyes with DPA structure were synthesized. For investigation of the substituent effect, two different anchoring groups, namely, 1,3-dioxo-1Hbenz[de]isoquinolin-2(3H)-yl)benzenesulfonamides and 1,8-naphthalimide, were used. Design/methodology/approach Three organic dyes based on azo were selected, which contain various electron donor groups. Absorption properties of purified dyes were studied in solution and on photoelectrode (TiO2 and ZnO) substrate. DSSCs were prepared to determine the photovoltaic performance of each photosensitizer. Findings The results showed that all organic dyes form J-aggregation on the photoanode substrate. Cyclic voltammetry results for all organic dyes ensured an energetically permissible and thermodynamically favorable charge transfer throughout the continuous cycle of photo-electric conversion. The results illustrate conversion efficiencies of cells based on solution Dyes 1, 2 and 3 and TiO2 as 3.44, 4.71 and 4.82 per cent, respectively. The conversion efficiencies of cells based on solution Dye 1, 2 and 3 and ZnO are 3.21, 4.09 and 4.14 per cent, respectively. Practical implications In this study, the development of effect of assembling materials, offering improved photovoltaic properties. Social implications Organic dye attracts more and more attention because of its low-cost, facile route synthesis and less-hazardous properties. Originality/value To the best of the authors’ knowledge, the effect of anchoring agent and nanostructure on DSSCs performance was investigated for the first time.

“…Recently, immense efforts have been devoted to the preparation of nanofiber-based mats with various morphologies to reduce short circuits in batteries during charge/discharge at elevated temperatures. Electrospinning is considered the most efficient and cost-effective method to synthesize nanofibers with various morphologies, including core-shell [32] , multilayer [33] , hollow [34] , and porous [35] structures. To sum up, electrospinning is a convenient technique to fabricate ultralong nanofibers with low diameters (20 nm) [36] .…”

Dye-sensitized solar cells have been massive attention research because they are easy in fabrication, low-cost, sustainable, abundant material dye sources and high efficiency in power energy conversion. The natural dye that was extracted from Mimosa pudica Linn is potential to be used as a sensitizer for Dye-Sensitized Solar Cell. In this work, the dyes were extracted from three parts of plants; leaves, flowers, and the mix. TiO2 was used as the active material for semiconductor and applied by using the Doctor Blade method. Testing cells and the measurement of the voltage and the current were done outside under the sun irradiation. The UV -Vis spectra of the dyes indicated that the absorption of the three samples shows significant absorptions in quite similar wavelengths, approximately 665 nm. The DSSC cells had 0.16 %; 0.12 %; 0.01 % of conversion energy efficiency for flowers, leafs and mix respectively. These results indicated that the dye which is extracted from the flower of Mimosa pudica Linn is higher among all extracts.
