Mesoscopic injection solar cells operate in an entirely different fashion than conventional solar p‐n junction devices. Mimicking the principles that natural photosynthesis has used successfully over the last 3·5 billion years in solar energy conversion, t ...
Four Zn(II)-tetra(carboxyphenyl)porphyrins in soln. and bound to metal oxide (TiO2, ZnO, and ZrO2) nanoparticle films were studied to det. the effect of the spacer length and anchoring group position (para or meta) on their binding geometry and photoelectr ...
The effect of RC attenuation was not correctly taken into account. This led to a misinterpretation of the photocurrent response data that was in Figure 3a on page 17717 and further discussion. Under operating conditions, electrons are accumulated throughou ...
A series of new hybrid organic-inorganic molecules were prepared either by grafting of aminopropyltriethoxysilane (APTS) on silica nanoparticles followed by quaternarization of the nitrogen with ethyl, heptyl and isopropyl iodides or by grafting of N,N,N-t ...
Five ionic liqs. (ILs) Im+A-, where Im+ = 1-methyl-3-n-butyl-imidazolium, A- = I- (1), BF4- (2), SCN- (3), CF3CO2- (4), and CF3SO3- (5), were used in electrolytes for dye-sensitized monolithic solar cells. The properties of the electrolytes and various cha ...
Zn stannate (Zn2SnO4) 27 nm particles were synthesized by hydrothermal treatment. Nano-porous Zn2SnO4 thin films were prepd. on conducting glass substrates and used as working electrodes in dye-sensitized solar cells (DSSCs). Their behavior was compared wi ...
Five novel perylene mols. with different intramol. charge-transfer (ICT) characters have been synthesized. The relation between the ICT character for different donating groups and the results for their electro- and photochem. properties as well as their pe ...
Gas barrier coatings based on single or multiple layers of metals, oxides or nitrides are widely used on polymer substrates in applications ranging from food packaging to organic displays and solar cells. These coatings exhibit a residual permeability resu ...
A series of allyl-functionalized imidazolium salts are reported, including 1-allyl-3-ethylimidazolium iodide and 1-allyl-3-propylimidazolium iodide, which have m.ps. close to room temp. and show typical properties of supercooled fluids if heated above thei ...
Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
