The Si core–poly(N-isopropylacrylamide) shell (Si@PNIPAM) particles enable the bottom-up fabrication of large-area, cluster-free Si Mie-resonant submonolayers with well-controlled interparticle spacing through slot-die coating on glass substrates. The resulting Si submonolayers were successfully integrated into colored photovoltaic (PV) modules, providing vivid and uniform coloration with only a modest reduction (less than 10%–20%) in relative PV photocurrent. These results highlight the potential of self-assembled dielectric nanophotonic platforms for scalable and aesthetically appealing solar-energy technologies.
