The electrolyte is one of the key components for DSC and its properties have great influence on the photo-conversion efficiency and stability of the devices. Five new low volatile electrolytes containing 3-methoxypropionitrile (MPN) as solvent were prepare ...
We review herein several important aspects of surface chemistry in Li-ion batteries, and discuss the use of ionic liquids (ILs) for rechargeable Li batteries. We explored the suitability of ILs for 5 V cathodes and Li-graphite anodes. Some advantages of th ...
Ultracapacitors, also called electrochemical double layer capacitors (EDLC) or supercapacitors, may improve the performance of conventional electrolytic capacitors in terms of specific energy, or improve the performance of rechargeable batteries in terms o ...
Org. thiolate/disulfide redox couples were synthesized and were studied systematically in dye-sensitized solar cells (DSCs) from an org. dye (TH305). Photophys., photoelectrochem., and photovoltaic measurements were performed to get insights into the effec ...
Semiconductor films prepd. by electrostatic layer-by-layer deposition can be used to fabricate dye-sensitized solar cells after treatment at 150°. However, the resulting photocurrent is less than when the film is sintered at 500°. The difference in short-c ...
Photoactive NiO electrodes for cathodic dye-sensitized solar cells (p-DSCs) have been prepd. with thicknesses ranging between 0.4 and 3.0 μm by spray-depositing pre-formed NiO nanoparticles on fluorine-doped tin oxide coated glass substrates. The larger th ...
Electropolymn. of 3,4-ethylenedioxythiophene (EDOT) was performed in an aq. micellar soln. onto conducting glass and conducting flexible plastic substrates using a simple, scalable process. The background electrolyte in the process consisted merely of a mi ...
The authors report on the prepn. of interhalogen ionic liqs. [K+]XY2-, where K+ = 1,3-dialkylimidazolium, 1,2,3-trialkylimidazolium, or N-alkylpyridinium; XY2- = IBr2- or I2Br-. These compds. were characterized in soln. and the solid state by NMR, IR, Rama ...
Due to their high efficiencies and their potentially low production costs, dye-sensitized solar cells (DSSC) have attracted much attention during the last few years. The technology is based on a layer made of mesoscopic TiO2 film which significantly increa ...
Disclosed is a photovoltaic cell comprising a substrate having an electrode layer (1) on the surface and having a porous metal oxide semiconductor film (2) which is formed on the electrode layer (1) and on which a photosensitizer is adsorbed, a substrate h ...
