Brian O'Regan and Michael GrÃ¤tzel invented the dye-sensitized type of these devices, which may alternatively make use of materials like cadmium telluride and copper indium gallium diselenide.
One type of these devices is subject to the Staebler-Wronski effect. C.H. Henry developed a graphical method for analyzing the theoretical performance of another type of these devices against the AM1.5 standard. Brian O'Regan and Michael GrÃ¤tzel invented the dye-sensitized type of these devices, which may alternatively make use of materials like cadmium telluride and copper indium gallium diselenide. Multiple (*) exciton generation enables nanocrystal varieties of these devices to exceed the Shockley-Queisser limit on their efficiency in the single- junction case. Polycrystalline silicon is the most common material used to make these devices, which operate in the fourth quadrant of an I-V diagram and produce electron-hole pairs by absorbing photons. For 10 points, name these devices that generate electrical power from sunlight.
