Summary: This study presents the design and fabrication of a photoanode composed of Au/SnS/TiO2 sensitized with natural dye for dye-sensitized solar cells (DSSCs). By calcination, a layer of spherical nano-TiO2 is prepared, and a layer of nano-SnS is deposited on the TiO2 photoanode using the continuous ion layer adsorption reaction (SILAR). The sensitized Au nanoparticles exhibit enhanced localized surface plasmon resonance (LSPR) effects and electron trapping ability, resulting in improved electron mobility and reduced electron recombination in the DSSC.

Summary: In this study, three types of TiO2 photoelectrodes were fabricated and evaluated for the dye-sensitized solar cells using synthesized organic photosensitizers. The double-layered nanoporous TiO2 photoelectrode showed the highest efficiency, compared to the single-layered nanoporous TiO2 photoelectrodes. The relationship between photovoltaic effects and interfacial resistance characteristics could be interpreted from impedance analysis.

Summary: The Rhodamine-6G derivative Rhd and its metal complexes with aluminum and chromium ions were synthesized and characterized using UV-vis and fluorescence spectroscopy. Dye-sensitized solar cells (DSSCs) were fabricated with Rhd and the metal complexes, and their solar-to-electric power efficiencies were determined through current-density measurements and Electrochemical Impedance Spectroscopy (EIS). The Rhd and Cr3+-sensitized solar cell showed the highest solar to electric power efficiency at 0.16%.

Summary: Three novel push-pull dyes, AJ502, TZ101 and TZ102, were synthesized and used as co-sensitizers in dye-sensitized solar cells (DSSCs). Among them, the co-sensitization of AJ502 with TZ101 and TZ102 significantly improves the power conversion efficiency of the DSSC, with the fluorine atoms in TZ101 playing a critical role in widening the active light capturing bands on the TiO2 film.

Summary: The facile synthesis and application of nano-sized semiconductor metal oxides for optoelectronic devices are challenging due to multi-step processes. Semiconductor oxides derived directly from metal-organic frameworks (MOFs) show promise for clean energy conversion and storage devices, with the potential to enhance light absorption in the visible region and improve overall performance.

Summary: The study presents robust QSPR models developed for five chemical classes of organic dyes (Triphenylamines, Phenothiazines, Indolines, Porphyrins and Coumarins) to predict absorption maxima values. These models were internally and externally validated, and consensus predictions were made for dye categories using an intelligent consensus predictor tool.

Summary: The development of novel bilayer photoanodes is crucial for efficient dye-sensitized solar cells. In this study, a homojunction photoanode consisting of undoped and Ni-doped TiO2 layers was prepared. By tuning the location of the doped layer, the photoconversion efficiency was greatly improved. The bilayer structure enhanced light absorption, resulting in increased short circuit current and open-circuit voltage.

Summary: A series of double donor organic dyes, ME101-ME106, designed in this work based on experimentally synthesized dye WD8, show higher stability and electron performance than the single donor dye. Among them, ME106 exhibits potential application value with a smaller energy gap and significant redshift compared to WD8. Results suggest that double donor dyes have stronger electron transfer capability, offering new insights for the design of high efficiency dye-sensitized devices.

Summary: Here, a metal-free organic dye (CCPICPB) with panchromatic absorption in the near-infrared range was synthesized. The dye's photophysical properties were studied and validated through experimental and theoretical simulation. Pristine and calcium-doped TiO2 microspheres were synthesized using a solvothermal approach. The performance of CCPICPB dye on these materials was evaluated, with the Ca-TiO2 photoanode-based device showing higher efficiency. Co-sensitization of CCPICPB dye with Ru(II) dye resulted in further efficiency improvement, attributed to improved V-OC and J(SC) due to the dye's compensatory effect and inhibition of electron recombination.

Summary: This paper demonstrates the application of a novel ternary nanocomposite MoS2/Ag/TiO2 photoanode in high efficiency plasma dye sensitive solar cell. The ternary nanocomposite MoS2/Ag/TiO2 was successfully synthesized without any hazardous substances. The addition of MoS2 improves the light absorption ability and electron transfer rate of the photoanode, leading to a significant enhancement in the photoelectric conversion efficiency of the dye sensitive solar cell.

Summary: Dye-sensitized solar cells (DSSCs) are a promising technology for clean energy conversion. This study focuses on enhancing the efficiency of DSSCs by optimizing charge transport and non-radiative carrier recombination. The introduction of Ti3C2Tx MXene into the photoanode improves electron transport and increases the energy-to-current conversion of DSSCs.

Summary: In this study, a one-dimensional protrusive TiO2 strip array was fabricated using chemical and physical methods. A porous semiconductor layer was coated on the strip array. The results showed that the DSSC with the TiO2 strip array had a higher energy conversion efficiency, which can be attributed to the large surface area of the protrusive structure and its specific electron transport paths.
