Abstract: Ordered Mesoporous Silica with Uniform Pore Size Was Prepared by Using Pluronic P123 as the Structure-Directing Agent. their Characteristics Were Analysized by TEM and a N₂ Adsorption System. Ionic Liquid-Based Gel Electrolyte Was Fabricated by Using Ordered Mesoporous Silica as the Framework Materials to Solidify Ionic Liquid Electrolyte. the Diffusion Coefficient of I₃^- in Gel Electrolyte Is Higher than that in Ionic Liquid Electrolyte due to the Formation of Favorable Channel for I₃^- Diffusion. the Optimized Overall Conversion Efficiency of Dye-Sensitized Solar Cells with Ionic Liquid-Based Gel Electrolyte Was 5.22% under Irradiation of 60 MW Cm^-2.

Abstract: Mesoporous carbon (MC) materials with surface area of 400 m²g^-1 were prepared and incorporated into the polymer gel electrolyte comprising of polyvinylidene fluoride and 1-methyl-3-hexylimidazolium iodide to fabricate the composite gel electrolytes. The photovoltaic performance of the quasi-solid-state dye-sensitized solar cells was improved through incorporating MC into electrolyte. The dye-sensitized solar cell with composite gel electrolyte containing 3 wt% MC achieved the best photovoltaic performance, and the corresponding open-circuit voltage, short-circuit current density, fill factor and overall conversion efficiency were 0.59V, 13.22 mAcm^-2, 0.66 and 5.15%, respectively. The stability of dye-sensitized solar cells with composite gel electrolyte was far superior to the cell with organic liquid electrolyte.

Abstract: Nanoporous carbons were prepared from rice husk (RH) according to a three-step procedure that includes pre-carbonization, silica removal and chemical activation. The surface area and pore structure of the nanoporous carbons are characterized intensively using N₂ adsorption technique. The as-prepared carbons have specific surface area of up to 3283 m²/g, and total pore volume of up to 1.8 cm³/g. The effect of activating agent dosage on the pore structure of carbons was investigated and elucidated clearly. As evidenced by electrochemical measurements, the as-prepared carbons have good capacitive performances and their specific capacitances are much higher than ordered mesoporous carbon, thus highlighting the success of preparing high performance electrode material for EDLC from a biomass waste, rice husk.
