Geometrical-optics resonator photonics

Conventional waveguide optical resonators face inherent limitations of low damage thresholds, limited coupling tunability, and stochastic resonance. To overcome these, we introduce a geometrical-optics resonator (GOR) framework, emulating free-space reflection and thin-film coupl...

Solution‐Processed Sandwich‐Structured Organic Photovoltaics

Current organic photovoltaic (OPV) devices still rely on complex multilayer architectures, which inevitably increase OPV production costs. Here, we propose a simple sandwich‐structured OPV device composed solely of a bottom electrode/active layer/top electrode configuration, with...
