“…The luminescent material absorbs the incoming sunlight and re-emits it in longer wavelengths. A fraction of the re-emitted light undergoes total internal reflection and eventually reaches the edge of the semitransparent plate; this light is collected by the solar cells along the edges [ 4 ]. LSCs are intended to replace large PV modules with polymer- or glass-based plate collectors, which are lightweight and adaptable with regard to color, shape, and size.…”

In this study, a negative replica layer of leaf surface microstructures was used to cover the top surfaces of semitransparent thin-film luminescent solar concentrators (LSCs) to enhance the concentrators’ performance. With low reflection on the air–glass interface of the glass plate in a thin-film LSC, a negative replica layer enables the scattering of incident sunlight and increases the path of light transmitted into the LSC and the thin phosphor layer at the bottom surface of the LSC. The incident sunlight is therefore more likely to interact with the phosphor particles in the thin-film phosphor layer, thereby enhancing the performance of the LSC. In this study, semitransparent thin-film LSCs with different inorganic phosphors were examined. The experimental results revealed that the optical collection efficiency of semitransparent thin-film LSCs covered with negative replica layers of leaf surface microstructures was higher than that of the semitransparent thin-film LSCs without negative replica layers. Furthermore, the LSCs with negative replica layers with high haze ratios exhibited high optical collection efficiency. Integrating negative replica layers of leaf surface microstructures as semitransparent layers in thin-film LSCs may optimize the application of LSCs in building-integrated photovoltaics (BIPVs).

Incorporating specific motifs to provide tangible evidence of authenticity is a direct and effective measure against counterfeiting. However, achieving multi‐level anticounterfeiting through multiple motifs requires utilizing numerous stimulus sources to configure region‐specific emissions with customizable colors, which is complex, costly, and inaccessible. To address this challenge, a hybrid luminescent display is developed by integrating an internal down‐conversion layer with an organic light‐emitting diode (OLED). The internal down‐conversion layer can effectively extract the substrate and waveguide modes, resulting in a very rare outcome where the efficiency of a hybrid down‐conversion white OLED exceeds that of the pump light source. More importantly, by combining voltage‐modulated color‐tunable electroluminescence (EL) with EL‐induced down‐conversion luminescence, this unique design can precisely create dynamic and configurable multi‐color display patterns using only electrical stimulation. For anticounterfeiting purposes, the further amalgamation of the dynamic hybrid luminescent display device with the Internet of Things for digital authentication, and with fingerprint features for physical unclonable functions showcases unprecedented security. These results herald a new generation of multilevel luminescent anticounterfeiting technology.
