报告摘要:

In this talk, photoconversions based on photovoltaic effect and hot-electrons will be introduced, respectively, with addressing both the simulation and experiments.From the perspective of energy, optoelectronic and thermodynamic simulation showing profound light-matter interactions as well as multi-physical responses of photovoltaic devices play a significant role in solar cell designs.We perform a comprehensive model of photovoltaic devices with considering optical, electrical and thermal effects, which are fully-coupled in multi-physical domains. The talk will introduce our recent works in light-trapping, photoconversion-improvement, as well as the profound simulation technique of nanostructured solar cells.Moreover,I will present our recent studies on the design of purely planar configurations for hot-electron photodetection. In the planar systems, we carefully design the multilayered planar configuration composed by one-dimensional dielectric photonic and metallic hot-electron collection components, so that the so-called Tamm plasmons can be excited to harness the incident photon energy in an efficient way. We consider both the metal-semiconductor-metal system as well as the Schottky system composed by only metal-semiconductor junction. A detailed optical and electrical design and performance characterization will be presented. The fabrication and performance evaluation of the nanostructured systems for solar energy harvesting will be introduced as well.
