The presented examples of recent achievements in immunosensor development show the tremendous progress in this field. Detection limits lower continuously, miniaturized setups by keeping the possibility of automated production progressed, and procedures for detection are constantly simplified. Direct immobilization of the receptor antibody by photochemical reactions enables the production of ready to use immunosensors in few steps. With photovoltaic components, time consuming and expensive labeling procedures of the analyte can be avoided. 

Silicon is used in the semiconductor industry for making transistors and photovoltaic components for electronic circuit boards. It is used in metallurgy for steel and nonferrous alloys based on copper, bronze, and aluminum. 

Several attempts to use otganic polymeric semiconductors as the active component in photovoltaic devices have been reported during the last two decades. Interest in the photovoltaic properties of conjugated polymers like polyacelylcne, various derivatives of polythiophenes and poly(para-phenylene vinylene)s arose from... 

Optoelectronic components produced by CVD include semiconductor lasers, light-emitting diodes (LED), photodetectors, photovoltaic cells, imaging tubes, laser diodes, optical waveguides, Impact diodes, Gunn diodes, mixer diodes, varactors, photocathodes, and HEMT (high electron mobility transistor). Major applications are listed in Table 15.1.El... 

Amino pyrimidine-terminated oligothiophenes such as 78 were components of donor-acceptor photovoltaic devices <06T2050>. 

The Hydrogen Research Institute in Canada has developed and tested a stand-alone renewable energy system composed of a 10 kW wind turbine, a 1 kWpeak photovoltaic array, a 5 kW alkaline electrolyzer, and a 5 kW PEM fuel cell. The components of the system are electrically integrated on a 48 V DC bus [50].

In nonbiological applications, mixed ruthenium complexes of bipyridyl ligands and substituted pteridine diones have been used as components of photovoltaic cells <2002JPH167>. When fabricated into sol-gel processed titanium oxide electrodes, these complexes achieved photocurrent conversion efficiency in the range 20 8%. 

Films designated as Sn(0,S) were deposited from a solution containing tin(IV) acetate, HCl, and thioacetamide (the concentration of the latter two components determining the S 0 ratio) [108]. These films were prepared as buffer layers for photovoltaic cells (see Chap. 9), and little characterization of the films themselves, other than some XPS, was reported. The XPS results suggested that the films were a mixture of Sn02 and some Sn-S species. 

Benzothiadiazole-containing polymers, (III), were prepared by Brabec et al. (3) and used as a component in photovoltaic cells. Benzothiadiazole copolymers were also prepared by the authors (4). 

Once the synthetic methodologies were developed, the research efforts were focused on the preparation of photoactive systems where fullerenes had already shown potential applicability, such as organic photovoltaic materials. In these molecular-scale engineered systems, a fullerene electron acceptor contained in one submolecular fragment is coupled with an electron donor contained in the opposite component. Zinc porphyrins were thus coupled to in many different architectures such as, for instance, in that shown in Scheme 9.11, where the ZnP was appended to...
