How can colored PV systems be realized?

This work reviews possible approaches to realize colored PV systems by implementing semitransparent cells, selective reflective films, and luminophores. Additionally, the research progress to minimize light sacrifice for color production has been investigated.

Can PV modules be colored?

During the past few years, the coloring methods of PV modules have been most intensively studied.

Can colored functional coatings improve the PCE of PV modules?

The equilibrium temperatures of the colored Si PV modules are only 2∼3 K higher than the ideal equilibrium temperature. These results indicate that these colored functional coatings can achieve excellent radiative cooling effects on PV modules and improve the PCE of PV modules. 4. Conclusion

Why are PV panels black?

The black color of the traditional PV panel is caused by the use of a thick semiconductor layer to absorb most incident light. To create colored PV panels, thinner semiconductor layers must be used.

What is the equilibrium temperature of Si PV modules with functional coatings?

The equilibrium temperature of Si PV modules with functional coatings is only 2∼3 K higher than the ideal minimum. This work provides an alternative and convenient method to design the structural colored PV module with radiative cooling for effectively balancing PV module color and PCE, promoting the development of BIPVs. 1. Introduction

Do colored PV modules reduce PCE?

As the reduction in solar transmittance is insignificant, the J - V curves of all colored PV modules keep close to the normal black PV module. In comparison to bare Si PV modules, the incorporation of a color-controlling functional coating reduces the amount of solar energy on the Si solar cell, hence reducing a portion of the PCE.
