Abstract
The effect of light and heat is studied on the electrical properties of an electrochemical n-InP/aqueous solution of orange dye/C cell. The cell is investigated under the light and heat of filament bulb. The n-type indium phosphide and carbon plates are used as electrodes. The aqueous solution of organic material orange dye (C17H17N5O2) in distilled water is served as electrolyte at 1, 3 and 5 wt. % concentration. The cell is assembled in sealed organic glass box with dimensions 35 x 13 x 14 mm The open circuit voltage (V-oc) and short circuit current (I-sc) of the cell are observed by illuminating and heating the samples. The temperature is raised up to 60 degrees C from 25 degrees C when light intensity is increased from dark condition to 425 W/m(2). It is observed that the relationship between light intensity and temperature is approximately linear for all cases. The V-oc and I-sc increase 100% and 300% respectively by increasing the light. The reported n-InP/aqueous solution of orange dye/C cell can be considered as small converter of light and heat into electric power.
