Thin films of solid-state polymer electrolytes for dye-sensitized solar cells

Effect of Interfacial Polarization on the Trap Passivation and Dielectric Constant of SrF2/TiO2 for Dye-Sensitized Solar Cells

“…This was corroborated by the higher chemical capacitance C μ (3.472 μF) and J sc (13.42 mA/cm 2 ) of SrF 2 /TiO 2 ( %w/w 10/90)-DSSC than the control-DSSC (3.264 μF; 13.05 mA/cm 2 ). Further, the reduced C μ in the high composition of SrF 2 (20 and 30 wt %) in the TiO 2 photoanode confirms the upshift in quasi-Fermi level of the TiO 2 photoanode . It tends to increase the V oc of DSSCs made with SrF 2 than pure TiO 2 -based DSSC and maintains its excellent electron injection from the dye molecule.…”

Recent advances in the approaches for improving the photovoltaic performance of porphyrin-based DSSCs

“…On this basis, the development of novel electrolytes deserves further research for further enhancing the photovoltaic performance. [130][131][132][133] (3) The photoanode needs to be optimized. In this respect, the development of multifunctional composite photoanode and pre-adsorption of a monolayer of a hydroxamic acid derivative have been elucidated to be effective approaches.…”

High-Performance Carbon Black-Based Counter Electrodes for Copper (I)/(II)-Mediated Dye-Sensitized Solar Cells

“…In the past 30 years, several metal dyes, organic dyes, iodide, copper, and cobalt redox couples-based liquid electrolytes (LEs) have been developed for DSSCs to achieve high PCEs under different light conditions. ,, DSSCs have a higher PCE under ambient light than under sunlight. − Considering the various advantages of DSSCs, small and large-area module DSSCs have been fabricated for terrestrial power generation and powering portable electronics, respectively, especially for Internet of Things (IoT) devices. ,, DSSCs prepared using organic dyes and copper redox couples achieved high efficiencies of 15 and 37% under one-sun and room light conditions (7000 lx), respectively. , However, the leakage and evaporation of solvents especially at high temperatures lead to poor stability of DSSCs, thus still affecting the commercialization of these cells . To improve the stability without loss in the PCEs, polymer gel − anprintable electrolytes, , as well as solid-state redox electrolytes, , have been developed instead of LEs. The cells using cobalt polymer electrolytes , and solid-copper redox electrolytes , have high PCEs and stability under one-sun and room light conditions.…”
