제목 Coupling of carbon quantum dots based planner waveguide with polymer dispersed liquid crystal window for light harvesting application
초록 This study describes a complementary coupling of carbon quantum dot based waveguide with PDLC smart window device that selectively harvests the UV for energy generation without competing for the visible and near-infrared light. The hybrid device can be switchable between transmissive and opaque light state while simultaneously generating energy. Spectral characteristics of the light transmitted through the device confirm that all the UV photons are harvested while most of the visible, near-IR and IR photons are transmitted. The colorimetry analysis of the prepared devices is performed to realize their compatibility with visual comfort of individuals residing in the building with such windows. It is demonstrate that scattering effect during the OFF state of the waveguide-coupled PDLC device is responsible for its improved optical and power efficiencies (4.52% and 2.49% respectively) as compared to that in the ON state of PDLC.
