From our results we determined that the best filter color is between yellow and red, so a wavelength of anywhere between 600 nm to 700 nm. The larger we get, the small the voltage would be produced because the wavelengths are getting to large to power the solar cell.
The colours were optimized by allowing the solar cells to reflect light within two distinct wavelength bands in the visible region. Colour chromaticity and brightness were controlled by modifying the position and width of the reflection bands, while optimising the band-gap energy for each colour.
This activity demonstrates the ability of solar cells to absorb at different wavelengths of the electromagnetic spectrum and shows how the more it can absorb, the more power it produces.

Colour can improve the visual aesthetics of solar cells for building and product integration but constitutes an optical loss from the perspective of photovoltaic energy conversion. To quantify this compromise, we report the theoretical efficiency limits of ideal coloured opaque single-band-gap solar cells.
For most colours, except the darkest ones, the optimal band-gap energy for a theoretically ideal solar cell is between 1.115 eV and 1.135 eV, matching the value for crystalline silicon. The results clarify the link between the solar cell colour and efficiency and establish a reference point and guidelines for optimizing coloured photovoltaics.
A certain fraction of incident light bounces off the surface of the cell without encountering an electron. To reduce losses from reflectivity and increase efficiency, solar cell manufacturers usually coat the cells with a nonreflective, light-absorbing material.
