Abstract: In this paper, an attempt has been made to evaluate the effect of colours of light on silicon photovoltaic cell. Various colour filters are used for estimating the output current performance of solar cell experimentally.With respect to colours of filter used the output voltage and output current from the photovoltaic cell is monitored. The results show that visible portion of the solar spectrum significantly influences the performance of the solar cell array.

Keywords: Solar PV array, Colour Filters, Output current, visible spectrum, Solar cell performance.
