The photoelectrochemical properties of the nanocrystalline TiO/sub 2/ electrodes sensitized by porphyrin derivatives with different functional groups, e.g., carboxyl, sulfonate and phenyl were investigated. It was found that the all porphyrin derivatives used in this study had sensitization effect. The interaction between the porphyrin and the TiO/sub 2/ surface is determined and compared using UV-vis spectra. The adsorption behavior of the porphyrin on the TiO/sub 2/ electrode surface was discussed. Furthermore, we examined the photoelectrochemical properties of a free base porphyrin with only one carboxylate group (H/sub 2/TC1PP), the result obtained was compared with that of porphyrin with four carboxyl groups (H/sub 2/TC4PP). It reveals that the higher photocurrent intensity of H/sub 2/TC4PP can be obtained than that of H/sub 2/TC1PP, and the energy conversion efficiency of the solar cell is very dependent on the structure of porphyrin. These results indicate that the binding state between the dye and semiconductor is an important factor affecting the properties of the dye-sensitized solar cell.","PeriodicalId":111348,"journal":{"name":"Proceedings of the 2001 1st IEEE Conference on Nanotechnology.

The LBT crystalline size - which is affected by La/sup 3+/ dopant content, drying temperature of quasi-gel and calicination temperature of dried gel - is the most essential factor that influences the humidity sensitivity and fabrication of the sensing element that composes the LBT polycrystals. The sensor, made of 15/spl sim/25nm powders, displays consistent humidity sensitivity and feasibility of fabrication. Therefore, the samples are divided into two classes according to the crystalline size. Those with the crystalline size from 15nm to 25nm are considered as ideal, while those with the crystalline size less than 15nm and more than 25nm are inconclusive. In order to obtain parameters assuring preparation of the polycrystals with the crystalline size from 15 to 25nm, a combination of a novel pattern recognition (PR) and artificial neural networks (ANN) has been utilized to design the process parameters.","PeriodicalId":111348,"journal":{"name":"Proceedings of the 2001 1st IEEE Conference on Nanotechnology.

Nanostructured layers were studied by scanning electron microscopy (SEM), Raman spectroscopy and photoluminescence. With Raman spectroscopy, it was found that the nearly free H/sub 2/-molecules in nano-voids appear in hydrogen plasma treated silicon. These nanovoids filled by hydrogen molecules are stable up to 400/spl deg/C. It was established by SEM that the treated samples exhibit structures with the typical dimensions well below 100 nm. It is shown that the doping of such nano-structured layers by phosphorous can be done during the hydrogenation which leads to the formation of high conductive nano-structures. After the Ar laser irradiation in air the nano-structured silicon layers exhibit a broad photoluminescence (PL) in the visible spectral range, which can be attributed to the evolution of chemical structures and dimensions of Si based nano-clusters due to the laser assisted processes. The advantage of the proposed method is that there is no need for any deposition process in this case to produce a Si-based nano-structured layer. The possible applications of the silicon-based nano-structured layers by the proposed method are discussed.","PeriodicalId":111348,"journal":{"name":"Proceedings of the 2001 1st IEEE Conference on Nanotechnology.
