Summary: Conductive polymer blend gel electrolytes improve the stability of dyesensitized solar cells by reducing leakage and enhancing electrode adhesion. In this study, polyvinylpyrrolidone (PVP) and polyaniline (PANI) blends were synthesized through in-situ polymerization and characterized using various methods. The optimal composition of the electrolyte solution was selected, and the conductivity was found to be influenced by salt concentration. Solid-state dye-sensitized solar cells with gel electrolytes exhibited better long-term stability compared to conventional cells.

Summary: Dye-sensitized solar cells (DSSCs) have the advantages of environmental friendliness, easy fabrication, and rich colors, making them promising for applications in architectural decoration and power supply for low energy devices. However, porphyrin dyes used in DSSCs still suffer from absorption defects and aggregation tendencies. In order to address these issues, various approaches have been developed to achieve panchromatic absorption and high efficiency.

Summary: This study investigates the use of diatom frustules incorporated into multilayer photoelectrodes to enhance the efficiency of dye-sensitized solar cells. It is found that the efficiency of cells with a diatom frustule composite layer is increased by 101% compared to the control cells. The enhanced efficiency is attributed to improved light absorption and dye adsorption facilitated by the scattering and trapping effects of diatom frustules.

Summary: A redox electrolyte plays a crucial role in dye-sensitized solar cells (DSSCs) by regenerating dyes and minimizing charge recombination. I-/I3- redox shuttle is commonly used but limits the open-circuit voltage. Cobalt complexes with polypyridyl ligands and Cu-complex-based redox shuttles have been utilized to improve the Voc value. The replacement of suitable ligands or an alternative redox shuttle with a redox potential of 0.45-0.65 V is required to use highly efficient porphyrin and organic dyes.
