Summary: Inhibition of electron recombination and dye aggregation is an effective strategy to enhance the power conversion efficiency of co-sensitized solar cells. In this study, the addition of EA and the introduction of oxyalkyl chains in the triphenylamine donor were found to significantly improve the molar absorbance of dye molecules and inhibit charge recombination and dye aggregation, leading to an increase in short-circuit current density. Moreover, the PCE of dye-sensitized solar cells based on the ternary co-sensitization system was greatly improved.

Summary: This study reports the improvement in panchromatic light-harvesting and photovoltaic performance of dye-sensitized solar cells through the adoption of co-sensitization technique by mixing dyes. Natural dyes, Betalain and Anthocyanin, extracted from beetroot and cranberries were used. The dyes were characterized by UV-Vis and FTIR spectroscopy, and solar cells were fabricated and electrically characterized. The solar cell sensitized with mixed dyes showed enhanced performance compared to cells of individual dyes, with a higher short circuit current density, open circuit voltage, and fill factor. The results suggest that mixing dyes from different natural sources can effectively improve the performance of dye-sensitized solar cells.

Summary: This paper presents a new approach for enhancing the performance of dye sensitized solar cells (DSSC) by combining co-sensitization and Förster resonance energy transfer (FRET) from natural pigments to synthetic pigment. The results show that natural pigments can be more effective in the FRET process as energy-donors compared to synthetic pigment, and sensitizing TiO2 directly with an organic synthetic pigment improves the loading capacity on the semiconductor.

Summary: A series of organic co-sensitizers (CS1-3) for thiourea dye D8 were designed and synthesized to enhance the conversion efficiency of organic dye sensitized solar cells (DSSCs). These co-sensitizers showed improved power conversion efficiency compared to devices without co-sensitizers, with CS3 exhibiting the highest PCE of 8.53%. The incorporation of a benzene terminal group in CS3 was found to prevent aggregation and electron recombination, contributing to the enhanced performance of the co-sensitized cells.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
