Abstract

Transmittance which is the fraction of incident light at a specified wavelength that passes through a sample and energy bang gap which is the energy difference between the conduction band and valence band are essential characteristics for analyzing the performance of a dye sensitized solar cell in relation to the solar energy absorbed. Anacardium occidentale dye which was used as the sensitizer gave a transmittance which increased gradually from the ultraviolet region through the visible range to the infrared region; having its peak and least values at 1099.15m and 299.87m of wavelength respectively. With a bang gap of 3.271eV, the dye gave a value of 1.48eV. The possible significance of these findings is discussed.
