Laminated transparent solar cell

An electrochromic device embodies a number of superimposed layers on a transparent substrate or between two transparent substrates, and optical transmittance is altered when an electrical potential is applied so that charge is shuttled between layers serving in the same way as anodes and cathodes in an electrical battery. One specific design with a five-layer construction shown in Figure 30 uses cathodically coloring WO3 and anodically coloring nickel oxide joined by an ion-conducting electrolytic laminate. A potential of a few volts, preferably supplied by solar cells, is applied between... 

A new silicone encapsulant for the solar industry is available that can enable flexible thin-film modules to be laminated cost effectively using roll-to-roll processing. Marketed under the trade name ELASTOSIL Solar 2200, this new product is transparent, pourable and non-corrosive. It vulcanizes rapidly at elevated temperature and reportedly features outstanding adhesive properties. In its cured state, it can provide all types of thin-film solar cells with effective long-term protection from chemical and mechanical stresses. Web www.wacker.com...
