报告介绍 | 报告摘要:
The relatively high efficiency of solar cells based on silicon (Si) has led them to dominate the solar cell industry for the past few decades. It is of current interest to develop the photon management with nanostructures since the ability to suppress the reflection and light trapping over a broad range of wavelengths and incident angles plays an important role in the performance of optoelectronic devices, such as photodetectors, light-emitting diodes, optical components, or photovoltaic systems. A variety of photon management strategies are developed for more efficient Si photovoltaic devices and are discussed in this talk.
报告人简介:
Dr. Jr-Hau He is an Associate Professor at Institute of Photonics and Optoelectronics & Department of Electrical Engineering, National Taiwan University and also a visiting associate professor at Electrical and Computer Engineering (ECE) department of University of California San Diego currently. He puts all his efforts into the design of new nanostructured architectures for Nanophotonics and the next generation of nanodevices, including Photovoltaics (PV), and Resistive memory. He is also involved in directly observing resistive switching of memory device using in situ transmission electron microscopy (TEM) and electron beam lithography technique. He is involved in spectroscopy and electron microscopy, including photoluminescence, Raman, contactless minority-carrier recombination lifetime, quantum efficiency, TEM, Scanning TEM, in situ TEM, and e-beam lithography for over 10 years.
Of particular interest in PV are efforts to understand light scattering and trapping in nanostructured materials and design next-generation solar cells. He is also interested in transport of charge carriers across these solar cells and improving light coupling to increase the efficiency of photoinduced charge separation. Dr. He’s group is also currently involving in fundamental physical properties of the nanomaterials, such as the transport and switching behavior of nanowire FETs. The nanotechnology he developed has been transferred constantly to the PV industry in Taiwan. Dr. He also serves as Accreditation Council of “Republic of China fine manufacturer association” to advise small and medium-sized enterprises to have innovation and product features in the marketplace.
He has garnered over 1700 citations for a body of work 100 peer reviewed journal articles with 23 of H factor over his career and had over 200 presentations in international conferences. His breakthrough researches have been highlighted by almost 30 scientific magazines such as Nature, SPIE newsroom, Semiconductor Today, Chemical & Engineering News, and Nano Today.
