CdSe(x)Te(x-1) polycrystalline solid solutions in electrochemical solar cells
Abstract
The photosensitivity of polycrystalline films of CdSe(x)Te(x-1) solid solutions obtained by spraying suspensions of finely dispersed CdSe, CdTe, and CdCl2 powders on a titanium substrate is investigated for x = 0.5-0.7. It is shown that the photosensitivity of the sintered layer depends to a large degree on recombination in the space charge region of the semiconductor and on its surface, this dependence being particularly pronounced in the case of fine-grained polycrystalline layers. Recrystallization, which reduces the total surface of microcrystals, decrease losses associated with recombination; recrystallization also reduces the density of defects which contribute to recombination in the space charge region.
