摘要: Abstract In this study, an ion conducting polymeric hydrogel (ICPH) is synthesized, characterized and used as a matrix for trapping the electrolyte solution to suppress deterioration of cathode electrodes dye-sensitized solar cells (DSSCs). Polymeric hydrogels are synthesized free radical cross-linking co-polymerization acrylamide (AAm) methylenebisacrylamide (BIS) crosslink agent in slab forms with same thickness. The polymer host by scanning electron microscopy (SEM). Impedance spectroscopy studies carried out frequency range 5 Hz–13 MHz at room temperature. It observed that while dielectric constant decreased, loss tangents increased increasing content which trapped ICPH. as-prepared ICPH/graphene electrodes, assembled material cathode, confirmed substitution platinum (Pt) counter electrode DSSCs. photovoltaic tests ICPH-DSSCs current–voltage (I–V) measurements it ICPH-DSSC exhibited significantly enhanced electrical properties such cell efficiency (PCE) reached 5.41% after using We predict work will open way fabricate DSSC devices based on conductive hydrogels.
