Molecular design and synthesis of acetohydrazonoyl cyanide structures as efficient dye-sensitized solar cells with enhancement of the performance of the standard N-719 dye upon co-sensitization

Mohamed R. Elmorsy et al.

Summary: Four novel acetohydrazonoyl cyanide compounds (5-8) with a triphenylamine moiety as an electron donor for dye-sensitized solar cells (DSSCs) were designed and synthesized. The compounds were well characterized and their properties were extensively investigated and compared to N-719 dye. The highest photovoltaic conversion efficiency was achieved by compound 8 (PCE, eta = 5.17%) due to its high photocurrent and photovoltage. It was used as a co-sensitizer along with N-719 to improve the performance of the cell.

New A 3 B-type naphthyl Zn(II) porphyrins as DSSC dyes: Effect of anchoring group and co-adsorption for enhanced efficiency

P. Ram Kumar et al.

Summary: Two new Zn(II) porphyrin dyes, ZnNPCA and ZnNPHy, with three naphthyl groups and one carboxyphenyl/hydroxyphenyl anchoring group, were synthesized using a mixed condensation approach. The dyes exhibited redshifted absorption and emission spectra compared to ZnTPP-COOH dye. The anodic shift in the reduction potential of ZnNPCA facilitated electron injection, and the dyes interacted positively with semiconducting TiO2, enhancing electron injection and light harvesting. ZnNPCA showed higher efficiency in dye-sensitized solar cells (DSSC) due to its higher dye loading on the TiO2 surface, and the addition of co-adsorbent DCA further improved the photovoltaic performance.

The application of a novel D-A- π - A phenothiazine-based organic dye with N719 in efficient parallel tandem dye-sensitized solar cells

Songqing Shi et al.

Summary: In this study, a novel D-A-π-A organic dye PTZ-15 was synthesized and found to be compatible and beneficial to the classical ruthenium dye N719 in terms of light-harvesting. Consequently, T-DSSCs with a double-sided Pt electrode consisting of a N719-based top cell and a PTZ-15-based bottom cell were fabricated and their performance was tested. The parallel tandem DSSCs (PT-DSSCs) exhibited a significantly increased short-circuit photocurrent density (J(sc)) of 20.62 mA.cm(-2) and photoelectric conversion efficiency (PCE) of 10.85% compared to conventional DSSCs based on single N719 or PTZ-15. Based on these findings, we propose a strategy to drive the further development of highly efficient T-DSSCs.

Optimization of fabrication parameters for efficient dye-sensitized solar cells based on dyes containing benzothiadiazole, indoline, and their co-sensitization

Baris Seckin Arslan et al.

Summary: In this study, the fabrication of dye-sensitized solar cells (DSSCs) based on metal-free dyes RK1 and D205 was optimized by adjusting the TiO2 composition, solvent type, sensitization time, utilization of co-adsorbent, and co-sensitization. The DSSCs based on RK1 and D205 showed the highest power conversion efficiency (PCE) when fabricated using methanol and tetrahydrofuran as solvents, respectively. Additionally, a stepwise co-sensitization strategy was employed to enhance the overall performance of the DSSCs, with the co-sensitized solar cell achieving a panchromatic spectral response and an improved PCE compared to RK1-sensitized solar cells.

Theoretical calculation of the influence of internal acceptor on photovoltaic performances in triphenylamine-based dyes for dye-sensitized solar cells

Abdelhamid Khadiri et al.

Summary: In this study, the efficiency of D-A(2)-pi-A1 series metal-free organic dyes in dye-sensitized solar cells (DSSCs) was investigated. The insertion of internal acceptor between donor and pi-bridge moieties resulted in a red-shift in the UV-vis absorption spectra and improved photovoltaic properties. This study provides a theoretical basis for the design and structural modifications of dyes in DSSCs.

New D-A propeller system with pyridine core for co-sensitization in dye sensitized solar cells

Deepak Devadiga et al.

Summary: In this study, a propeller-type molecule with a pyridine core (D) was synthesized and found to have suitable light absorption properties and frontier molecular orbital levels for usage as a sensitizer in dye-sensitized solar cells (DSSCs), as confirmed by photophysical and electrochemical studies and theoretical DFT simulations. Moreover, the synthesized molecule was tested as a co-adsorbent dye in DSSCs using the standard dye Z-907, and showed improved performance in photocurrent, photo-voltage, and total power conversion efficiency compared to devices based solely on D or Z907.

Co-sensitization of 4-(thiophene-2-ylmethylene)thiazolidin-5-one dyes with Ru(II) complex N-719

Ismail Althagafi et al.

Summary: Five novel co-sensitizers were synthesized and studied for their co-sensitization effect with standard Ru(II) dye (N-719) in dye-sensitized solar cells (DSSCs). Among them, IS-11 and IS-12 showed the highest power conversion efficiencies of 8.32% and 8.09%, respectively, when co-sensitized with N-719. This improved performance can be attributed to their maximum J(SC) values, indicating the importance of efficient co-sensitizers in enhancing DSSC performance.
