High-performance multicrystalline silicon (HP mc-Si) from directional solidification has become the mainstream industrial material for fabricating mc-Si based solar cells for photovoltaic
The energy-efficient colorful Si PV module is achieved by transparent-colored radiative cooling. Si@SiO 2 nanoparticles with Mie resonance and PMMA are used to achieve structural coloration and radiative cooling, respectively. Different hues of colored Si PV modules are achieved with no more than 10% PCE loss.
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
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.
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
During the past few years, the coloring methods of PV modules have been most intensively studied.
For the Si PV module, the Psun is mainly divided into two parts, one is the part of solar radiation absorbed by the functional coating, and the other is that the Si PV module absorbs solar light from the total solar spectrum.
