Summary: Dye-sensitized solar cells (DSSCs) are cheaper and easier to produce than silicon-based solar cells. Carbon materials can be used as counter electrodes in DSSCs instead of platinum electrodes due to their catalytic characteristics and affordability. Copper (I) thiocyanate (CuSCN) has recently been considered a promising hole transport material for advanced solar cells. In this study, dye-sensitized solar cells were fabricated using carbon-graphite counter electrodes with solid-state CuSCN. The use of carbon-based composite with CuSCN counter electrode showed improved efficiency and stability, with a maximum conversion efficiency of 8.56% achieved under AM 1.5 solar conditions.

Summary: Thin films of solid-state polymer electrolytes (SSPEs) have been developed for dye-sensitized solar cells (DSCs) for the first time. Gel-electrolytes are prepared by utilizing a blend of poly(ethylene oxide) (PEO)/polyethylene glycol (PEG) and an acetonitrile-based iodide liquid electrolyte, and then cast onto a glass substrate to fabricate solvent-free SSPEs by evaporating the solvent. The SSPE films are sandwiched between photoelectrodes and counter electrodes to assemble the solid-state DSCs, and the PCE can be improved by introducing TiO2 nanofillers in the SSPEs. The high stability of the solid-state DSCs is demonstrated with a retention of 98% of their original efficiency after a 700-hour test period.

Summary: The ever-increasing global population necessitates a secure and ample energy supply, the majority of which is derived from fossil fuels. However, due to the immense energy demand, the exponential depletion of these non-renewable energy sources is both unavoidable and inevitable in the approaching century. Therefore, exploring the use of polymer electrolytes as alternatives in proton-conducting batteries opens an intriguing research field, as demonstrated by the growing number of publications on the subject. This paper provides a detailed overview of these characterizations, as well as recent advancements in characterization methods for proton-conducting polymer electrolytes in solid-state batteries. Each characterization is evaluated based on its objectives, experimental design, a summary of significant results, and a few noteworthy case studies. Finally, we discuss future characterizations and advances.
