Transformations of the wavelength of the light incident upon CdS/CdTe solar cells

A method for the improvement of the spectral response of the CdS/CdTe solar cell was proposed. The coatings of fluorescent coloring agent (FCA) on the cell made the cell sensitive to light at wavelengths below 510nm, transfor ming the wavelength of the incident light from non-incentive region (below 510 nm) to incentive region (above 510nm). The FCA coatings showed about 8% and 14% increases in the maximum power of the solar cell under the radiati ons of a white and day-light fluorescent lamp, respectively. Possible maxim um output powers were predicted by using a simple model for the external qu antum efficiency of the cell. (C) 2001 Elsevier Science B.V. All rights res erved.
