When covered with the yellow filter the cell produces more current than when covered with the red or blue respectively. The relative power production of the solar cell covered by the colored filter is about 73%, 64%, and 54% respectively for the yellow, red, and blue filters.
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.
The results showed that colored filters have no significant impact on the solar cell voltage output, which peaked since sunrise. However, the short-circuit current is affected by using the color filters. When covered with the yellow filter the cell produces more current than when covered with the red or blue respectively.
In reviewing all three figures, it is apparent that if solar cell effieciencies increased at lower wavelengths there could be increased power losses due to yellowing. Yellowing may be an aesthetic issue at this time, but as technology advances in solar cells there needs to be development in EVA materials as well.
Devi et al. [ 20 ], present the electrical output behavior of the solar panel covered with different colors and thickness glass sheets for three irradiance values, they provide that the peak power was recorded maximum for the red color sheet compared to the yellow, green, and blue glass sheet.

Solar Cell: Working Principle & Construction (Diagrams Included)
A solar cell functions similarly to a junction diode, but its construction differs slightly from typical p-n junction diodes.A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor.We then apply a few finer electrodes on the top of the p-type semiconductor layer.. These electrodes do not obstruct light to reach the thin p-type layer.

Why Are Solar Panels Blue? Reasons Behind the Color
Solar panels'' colors are not just about looks. They''re closely connected to how they''re built and how well they work. The color difference between monocrystalline and polycrystalline panels comes from the way light hits the silicon in each one. Interaction of Light with Silicon Crystals. Polycrystalline solar cells come from melted ...

Yellow is not the new black in perovskite solar cells
Perovskite-based solar devices offer higher conversion efficiencies than silicon. The only problem is that some of the most promising perovskites, namely caesium lead triiodide (CsPbI 3), are very unstable at room temperature. Under these conditions, they have a yellow colour, as the atoms in the crystal do not form a perovskite structure. For ...

Solar Power: How Different Colors and Distances affect Voltage
Our voltage versus filter color contradicts some of our original opinions about the correlation between the two.
