In order to fulfill the strong demands for the clean electric energy sources, much effort has been devoted to develop photocells with non-traditional materials, encouraging the researchers who have been mainly working on chemistry or materials science to be involved into the photocell study. The spectral response is one of the critically important characteristics of photocells, especially for those using newly developed materials. However, traditional apparatuses for the spectral response measurement, which usually consist of a white light source such as Xe-lamp and monochromator, are expensive for the newcomers in this field. In this context, we report here the prototyping of a simple device for the measurement of spectral response of photocells using LEDs. It is confirmed that the prototyped LED-based device can reasonably reproduce the spectral feature of the sensitivity of a photocell based on GaAsP.
