“…Lower efficiency observed in the Pb(II)–S cells is linked to low electron lifetimes due to lower chemical capacitance properties at the electrode/electrolyte interface. Their good recombination resistance could not improve the electron lifetime due to their poor low chemical capacitance yield. − Figure c displays the equivalent circuit model fitted for the obtained semicircles.…”

Pb(II) complexes of bis(N-1,4-phenyl-N-(4-morpholinedithiocarbamato)) as Pb(II)–S and bis(N-diisopropyl-N-octyldithiocarbamato) as Pb(II)–P were prepared and characterized by optical, structural, morphological, and electrochemical techniques. The scanning electron microscopy analysis of Pb(II)–P and Pb(II)–S complexes consists of cubic crystals. X-ray diffraction and high-resolution transmission electron microscopy spectral studies revealed that the diameter increases in length for alkyl chain groups. This study demonstrates that the cubic shape of Pb(II) complexes can be synthesized from aromatic and aliphatic dithiocarbamate ligands. Photoluminescence analysis of both complexes fell within the blue shift region. The CV curve for Pb(II)–S revealed redox curves and the box-like shape as an indicative of a capacitive behavior, signifying limited catalytic redox activity. The J–V results for both sensitizers displayed satisfactory conversion efficiency (% η) between 3.77 and 3.96%.

“…The works of [24] reported power conversion efficiency of 4.25 % on carbon counter electrode with a ruthenium dye. When compared with the records of [25] on same carbon counter electrode but with a natural dye, efficiency was very low, 0.48 %. Machida et al, worked with poly 3, 4ethylenedioxythiophene (PEDOT) counter electrode, their result showed lower charge transfer resistance with improved power conversion efficiency of 7.88 % [26].…”

Currently, the situation of the economy is drastically affecting the growth and development of some growing nations with regard to the energy sector. Most developing countries still depend majorly on fossil fuels. Considering the environmental nuisance arising from the dangerous emissions from the combustion of fossil fuels and climate concerns, there is urgent need to seek other alternative energy sources to meet up with the global energy consumption demands as the human population is steadily on the increase. Energy from the sun is one of the most alternative sources that can be assessed freely as well as help in mitigating global climate change. Recent advances on dye sensitized solar cells (DSSC) using natural dyes is a welcome advancement for replacing high cost ruthenium dye. The application of natural dye for DSSC is due to their abundance in nature, low cost, simple and safe extraction from various natural resources without requiring complex synthetic procedures. Dye enhances the performance of a DSSC by providing the source of photo excited electrons. Recently, there has been research on areas that supports the exploration of different photoactive natural dyes. In this paper, we reviewed some natural dyes, energy conversion efficiencies of NDSSCs, methods of dye extraction, characterization and various fabrication techniques for improved DSSC performance from various researched articles. It was observed that there were variations in the recorded DSSCs performances and this can be attributed to steps employed by the researchers in the methods of dye extraction and DSSC fabrication.

Research on Dye Sensitized Solar Cell (DSSC) fabrication has been carried out using a combination of dyes extracted from Curcuma xanthorrhiza and Anredera cordifolia. Each dye was extracted by treating pH 1 to 13 and then characterized using UV-Vis spectroscopy. The band gap energy was determined by using the cyclic voltammetric method. The UV-Vis spectrum of C. xanthorrhiza extract reveals the presence of curcumin components. The UV-Vis spectrum of A. cordifolia indicates the presence of chlorophyll and a trace of anthocyanin. C. xanthorrhiza extract had the least band gap energy in the acid phase, pH 1, at 0.66 eV, and the alkaline phase, pH 13, at 0.43 eV. The minimum band gap energy of A. cordifolia extract was determined to be 0.96 eV in the acid phase, pH 7, and 0.65 eV in the alkaline phase, pH 12. When A. cordifolia and C. xanthorrhiza extracts were mixed, with the best composition ratios being pH 7:pH 1 (3:2 ≈ pH 1.7) and pH 12:pH 13 (1:4 ≈ pH 12.6). The composition of this mixture was applied to the DSSC resulting in an efficiency of 0.096 and 0.147%, respectively.
