Design and fabricating processes

The cost of a PV device is determined by several factors. These include the kind of materials used and the amount of materials requited, choice of substrates, device design, and fabrication processes. Crystalline devices ate generally mote efficient, but thin-film devices ate anticipated to cost less in flat-plate configurations. The use of concentrated light permits retention of efficiency with simultaneous reduction in cost.

Despite the recent rapid development of secondary lithium ion/lithium polymer batteries, advanced technology development, designs, and fabrication processes are still being developed and introduced into the lead-acid battery industry. Table 1.1 shows the major advantages and disadvantages of lead-acid batteries. 

When comparing the templating process with chitosan composite fabrication, phase separation parameters can also be optimized to control pore size. In both examples, the nonconductive scaffold/binder was composed of a biopolymer to enhance biofilm formation for MFCs. In summary, a carbon-based hierarchical stmcture illustrates three aspects of material design and fabrication process a nanometric and/or compatible interface for the immobilization of biomaterials,... 

Chemical processing under "extreme conditions" of high temperatures and pressures requires more tliorough analysis and extra safeguards. As discussed in Chapter 7, e.xplosions at liigher initial temperatures and pressures are much more severe. Therefore, chemical processes under extreme conditions require specialized equipment design and fabrication. Otlier factors tlrat should be considered when evaluating a chemical process are rate and order of the reaction, stability of the reaction, and tlie healtli hazards of the raw materials used. 

The bubble cap has been studied extensively and several design recommendations have been presented over the years. The most complete and generally applicable is that of Bolles [5]. It should be stressed that proper mechanical interpretation of process requirements is essential in design for efficient and economic operation. There is not just one result, but a multiplicity of results, each unique to a particular set of conditions, and some more economical than others. Yet at the same time, many of the mechanical design and fabrication features can be identical for these various designs. 

The three classes of mechanical standards in TEMA are Classes R, C, and B representing varying degrees of mechanical details for the designated process plant applications severity. The code designations [TEMA—1988 Ed] for mechanical design and fabrication are ...

When unpleasant odors resulting from manufacturing processes or waste-disposal operations give rise to public complaints they should be identified and quantified prior to deriving methods of abatement. Such work is often innovative, requiring the design and fabrication of new equipment for the sampling and analysis of pollutants.

The design and fabrication of some gas-phase micro reactors are oriented on those developed for chip manufacture in the framework of microelectronics, relying deeply on silicon micromachining. There are obvious arguments in favor the infrastructure exists at many sites world-wide, the processes are reliable, have excellent standards (e.g. regarding precision) and have proven mass-manufacturing capability. In addition, sensing and control elements as well as the connections for the whole data transfer (e.g. electric buses) can be made in this way.
