GENNAI - International research base for energy and environmental technology
June 30, 3:00 pm
Engineering Research Center (ERC) , Room 490, ASU Tempe Campus
Speaker:
Tetsuo Takehara, Research Center for Advanced Science and Technology, The University of Tokyo
Abstract:
In this talk the Solar Quest and GENNAI activities will be outlined and introduction of BIPV installation in Japan will beprovided.
The Solar Quest Research Center for Advanced Science and Technology at the University of Tokyo will launch GENNAI
(Global Energy Navigating and Nature Apprehension Interdisciplinary), an international research association pursuing the harmony of
global energy and environmental issues “to conduct research on strategic planning and assessment for development of renewable or
green technologies, by integrating the expertise of world-class researchers, businesspersons and policymakers.

New approaches to nano-structured organic and hybrid solar cell materials
May 8, 2:30 pm
Engineering Research Center (ERC) , Room 490, ASU Tempe Campus
Speaker:
Neal R. Armstrong, Department of Chemistry/College of Optical Sciences, University of Arizona.
Abstract:
Organic materials, and hybrids of organic
materials with semiconductor nanoparticles, have been
envisioned for application in both portable power
(electricity) production and for production of chemical
fuels. Whether these new materials will be widely adopted
in such device platforms depends upon our ability to
control functionality, architecture, and energetics on
nanometer length scales.
This talk will focus on several different approaches to the
creation of new organic solar cells, using combinations of
electrochemical deposition of base layers, nanotexturing of
these layers and vacuum deposited crystalline organic dyes,
and capture of ligand-capped semiconductor nanoparticles
(for photoelectrochemical hydrogen evolution).
Refreshments will be served at 2:00 pm
Material Challenges for Green InGaN Injection Lasers
March 27, 1:30 pm
Engineering Research Center (ERC) 490, ASU Tempe Campus
Speaker:
Dr. Fernando Ponce, Department of Physics, ASU.
Abstract:
The last two decades have seen significant advances in the development of
visible light emitting devices and diode lasers. Red and blue lasers are
now available commercially. But green light, with the highest response for
the human eye, remains the most difficult to achieve efficiently using
semiconductor materials. This is due to the physical nature of the InGaN
alloys used for this purpose. There are three important aspects of InGaN
alloys which need to be understood and controlled: (a) relaxation of
lattice misfit, (b) thermodynamic instability, (c) polarization effects.
This talk will review recent advances in understanding the complexity of
the physics of these materials and will discuss the perspectives for
achieving high efficiency green light emitting devices.
