Konarka      Photovoltaic technology, in use for many years, was considerably improved by the incorporation of compatible dye, which Dr. Michael Grätzel developed and subsequently patented in the 1990's. The core of the dye-sensitized technology consists of nanometer-scale crystals of TiO2 semiconductor coated with a monolayer of light-absorbing dye and embedded in an electrolyte between the front and back electrical contacts. Photons in light are absorbed by the dye.      Relatively simple manufacturing requirements will allow dye-sensitized photovoltaic products to be manufactured globally, even in regions where sophisticated manufacturing and support infrastructure is unavailable.     With low-cost raw materials and relatively low-cost manufacturing technology and processes, deposited thin films have the potential to provide more than a 50 percent reduction in cost relative to traditional crystalline cell modules.
