I have come here today to ask you to prevent another TV or VCR or computerized machine tool or solar cell or superconductor story. I have come to ask you to lead so that we will not be the first of our nation s ten generations to leave its children a country less prosperous than the one it inherited. I have come here to ask you, for the sake of my children and all of America s next generation to have America do it right this time.8... 

In view of the recent research progress and novel applications, the authors pelieve that DSC will be regarded as tne next-generation solar cell tha can be popularized like electric appliances, such as TVs and videc tape recorders. The... 

Why is Ti02 used in dye-sensitized solar cells (DSCs) What other oxides would possibly be useful As discussed in this Chapter, next-generation CMOS ICs will employ high-K dielectric films as the gate insulator. A potential roadblock to this replacement is the possible incompatibility with current gate stacks - explain this problem, with possible solutions. 

As reviewed above, sub-GBs are concluded to be most serious defects preventing the improvement of overall performance of solar cells based on Si multicrystals. We, therefore, suppress the generation of sub-GBs on the basis of fundamental knowledge of its mechanism. In the next section, the generation mechanism of sub-GBs is discussed.

Photovoltaic (PV) cells are physical devices that operate on the principles of solid-state physics. Another class of device - one that is capable of splitting water - is based on photo-electrochemical reactions, which take place at electrodes that are light-sensitive. Photo-electrochemistry may serve to generate d.c. electricity (via dye-sensitized solar cells) and this can then be used to electrolyze water (as with PV cells). Alternatively, light illuminating an electrode may reduce water directly to hydrogen - a process known as photolysis . These two processes are described next. 

The liquid-junction photovoltaic cell has the advantages that the junction between electrolytic solution and semiconductor is formed easily and that polycrystalline semiconductors can be used. The principal disadvantage is that the semiconductor electrode tends to corrode under illumination. The electrochemical nature of the cell allows both production of electricity and generation of chemical products which can be separated, stored, and recombined to recover the stored energy. Liquid-junction cells also have the advantages that are attributed to other photovoltaic devices. Photovoltaic power plants can provide local generation of power on a small scale. The efficiency and cost of solar cells is independent of scale, and overall efficiency is improved by locating the power plant next to the load.72...

In summary, a variety of flexible energy harvesting devices including solar cells and piezoelectric devices have been developed to meet the requirement of next-generation portable or wearable devices. However, the power conversion efficiencies of electronic devices were largely limited by the high electrical resistance of flexible electrodes based on polymer substrates. Therefore, more efforts are required to develop new flexible electrodes with higher electrical conductivities.
