Summary: The research found that the photocurrent growth and decay in dye sensitized solar cells can be fitted with a biexponential model, and that lithium ions have an impact on the slower lifetime component, but not the faster component. Additionally, comparing different light exposure cycles showed that the shorter lifetime components were more prominent in shorter cycles.

Summary: This article focuses on enhancing the light-harvesting ability of dye-sensitized solar cells (DSSCs) by using silver nanoparticles thin films to improve light absorption. The results show that the silver nanoparticles thin films act as reflectors, which increase the reflectivity of the counter electrode and enhance the light absorption of the sensitized photoanodes, leading to improved power conversion efficiency.

Summary: Nanoparticles of zinc ferrite were synthesized and mixed with TiO2 to form a composite photoanode for dye-sensitized solar cell. The composite photoanode showed a wider absorption band and higher photoelectric conversion efficiency compared to pure TiO2. The power conversion efficiency of the composite photoanode-based cell was enhanced by 39% compared to the pure TiO2-based cell.

Summary: This study focuses on using upconversion phosphors (UCPs) to convert IR into visible light to enhance the efficiency of dye-sensitized solar cells (DSSCs). The addition of an optimal amount of UCPs significantly improves the power conversion efficiency (PCE) of DSSCs, while excess UCPs deteriorate efficiency due to rapid recombination and increased interfaces.

Summary: Productive electron transfer between dye and redox shuttle is crucial for high-performing dye-sensitized solar cells. This study demonstrates that noncovalent self-assembly of dye and redox shuttle via g-stacking interactions can increase the electron transfer rate. The use of a dye with pyrene-based donor group and a redox shuttle with pyrene substitution leads to enhanced dye regeneration and reduced recombination rate. A power conversion efficiency of 22.8% is achieved under fluorescent lighting conditions.

Summary: Increasing the electron transfer rate between the dye and redox shuttle by noncovalent self-assembly through pi-stacking interactions has been shown to enhance the performance of dye-sensitized solar cells. This study synthesized a dye with a pyrene-based donor group and tested it with two terpyridine-based redox shuttles. The results demonstrated that the presence of pyrene groups on both the dye and redox shuttle increased the rate of dye regeneration and resulted in a significantly higher power conversion efficiency under fluorescent lighting conditions.

Summary: Submicrometer-sized CeO2 crystals were synthesized by a hydrothermal reaction method, and their morphology varied among different shapes. The film formability and light-scattering ability of the CeO2 crystals coated on glass substrates depended on their morphology. The CeO2 light-scattering layer was found to enhance the short-circuit photocurrent density in DSSCs with nanoparticulate ZnO electrodes.
