In this study, we have investigated the effect of heating by filament lamp on the electric properties of a Zn/orange dye aqueous solution/carbon cell. A solution of 5 wt.% orange dye (C17H17N5O2) in distilled water is used as an electrolyte in the cell. Zinc and carbon rods serve as electrodes. Organic glass box with a height, width and thickness of 35, 30 and 14 mm, respectively was used as a voltameter. The effect of heating by light on the open-circuit voltage and shortcircuit currents were studied. As the intensity of light was increased up to 380 Wm-2, the cells temperature increased from 36 oC to 60 oC. It was found that the open-circuit voltage of the cell was approximately constant with the increase of temperature, whereas short-circuit current and accordingly output power of the cell increased by 1.6 times. The Zn/
orange dye aqueous solution/carbon cell potentially can be considered as a small converter of light energy into electric power.
