DOI: 10.1063/5.0044654
Abstract: To better suit the bandgap of solar cell, we proposed a novel theoretical model of solar thermophotovoltaic system, which consists of a concentrator, a surface-textured absorber, an emitter, a photovoltaic cell, and a downconversion layer.… read more here.

DOI: 10.1364/ol.447674
Abstract: Comet-tail-like interference patterns are observed using photons from the spontaneous parametric downconversion (SPDC) process. The patterns are caused by the angular-spectrum-dependent interference and the diffraction of a blazed grating. We present a theoretical explanation and… read more here.
