“…Moreover, the simulated fundamental PV parameters are compared with the other theoretical and experimental data, further showing our simulated results' validation. In this regard, the theoretically simulated and experimentally determined PV parameters, such as V oc (0.53V -0.68V), J sc (7 mA/(cm -2 ) -18 mA/(cm -2 )), η (3% -6%), and FF (47 -56) for various scrutinized well-known DSSCs in recent years are comparable to our simulated results, signifying the utility of the considered dyes in the DSSCs [75][76][77][78][79][80][81]. Table 7 shows that very small differences in these values of all the dyes are due to the similar lifetimes of an electron and stored charges in TiO2 [82].…”

It is essential to interpret and analyze the performance and effectiveness of dye which acts as the photon harvester component in dye-sensitized solar cells (DSSCs) applications with a molecular level insight. D2 dye was tested experimentally and proved to perform better than other investigated dyes. D2 in the fabricated solar cell achieved 690 mV of open-circuit voltage (\({\text{V}}_{\text{o}\text{c}}\)), 0.73 fill factor (\(\text{F}\text{F})\), 10.40 mA.cm− 2 of sort-circuit current (\({\text{J}}_{\text{s}\text{c}}\)), and a 5.27% of power conversion efficiency (\({\eta }\)). D2 is E)-2-cyano-3-(5-(10-(4-(di-p-tolylamino)phenyl)-6,12-bis(octyloxy)naphtho[7,8,1,2,3-nopqr]tetraphen-4-yl)thiophen-2-yl)acrylic acid compound with anthanthrene core as a π-linker substituted at 6–12 positions with nonane alkyl groups. The chemical structure engineering of D2 photosensitizer is predicted to have a significant role in DSSC devices. This work replaced the anthanthrene core with 694 kJ/mol resonance energy with other aromatic cores with different resonance energies (ranging from 255 to 529 kJ/mol). Seven dyes were designed to examine the effects of resonance energies of π-aromatic linker on the geometrical, optical, and photovoltaic parameters in the isolated and adsorbed (on TiO2 semiconductor) dyes forms. Comparison between the experimental data of D2 allow the validation of the theoretical approach and is used as a reference to evaluate the potential of the designed dyes in this application. In addition, the DSSC device was optimized using the SCAPS-1D software and successfully simulated the main electrochemical parameters.

“…Dye-sensitized solar cells are mainly composed of photoanodes, counter electrodes, and electrolytes. The photoanode is mainly composed of light-absorbing dyes and conductive electrodes [1][2][3]. After the attached dye of the photoanode absorbs the emitted light, the separation of electron hole pairs occurs.…”

The electrolyte is one of the key components of dye-sensitized solar cells’ (DSSC) structure. In this paper, the electrolyte formulation of a new DSSC with external photoanode structure was studied. Based on the idea that the electrolyte should match the light absorption and light path, iodine series electrolytes with different concentrations were configured and used in the experiment. The results showed that the external photoanode structure solar cells assembled with titanium electrode had the best photoelectric conversion ability when the concentration of I2 was 0.048 M. It achieved the open circuit voltage of 0.71 V, the short circuit current of 8.87 mA, and the filling factor of 57%.
