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.
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 corresponds to a relative performance loss of less than 14% compared to an ideal black solar cell. Yellow-green is the most efficient photovoltaic colour, whereas highly saturated blue, red and purple colours produce the lowest efficiencies, when compared at equal brightness.
The study resulted in a series of conclusions that not only can modify many optical properties of a solar cell offering a very high AVT, especially its color, but also produce a significant improvement in photovoltaic performance by integrating a functionally designed 1D-PC.
Thus, extraordinary color changes from blue to yellow could be achieved while keeping transparency. Thereupon, photovoltaic performance showed notable improvements, with Jsc increasing from 7.98 mA/cm2 to 9.95 mA/cm2 and 10.45 mA/cm2 for 1DPC5 − 425 and 1DPC3 − 650, respectively.
Minimizing these constraints and improving the performance characteristics of solar cells can be achieved by applying various photonic structures such as plasmonic nanowires, triangular and pyramid gratings, nanostructures, and photonic crystals (PCs) 15. PCs are among the best candidates for this objective.
