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 (C 17 H 17 N 5 O 2 ) 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 × 13 × 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°C from 25°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.
