Symposium EN19—Novel Inorganic Semiconductors for Optoelectronics and Solar Energy
Concerns about climate change and the growing demand for energy are motivating research in sustainable energy production and energy efficiency. The sun provides free and abundant energy, and its transformation through photovoltaics or solar fuel is a very important part of materials research. At the same time, development of optoelectronic semiconductors to advance energy efficiency through solid-state lighting, photonics for computing, etc. utilizes the same physical principles. More specifically, the understanding and control of key materials properties such as optical absorption and emission, carrier mobility, etc. are essential to the design and development of new energy technologies. This symposium will address fundamental and applied aspects of emerging optoelectronic semiconductors for solar absorbers and light emitting materials. We will highlight recent developments in both experimental and theoretical/computational approaches. The scope of this symposium is to provide a discussion forum for researchers working on the early stages of development of earth abundant and/or newly emerging materials for thin film photovoltaics, solar fuel production, solid-state lighting, and related materials such as transparent conductors. The focus will be on issues outside of those already well-developed industrially, such as silicon, III-V materials, and established thin films (e.g. CdTe, CIGS, ITO). Novel experimental techniques for synthesis and characterization as well as theoretical, computational and modeling methods are of interest. Presentations will focus on relevant materials, nanomaterials, interfaces and devices. Materials will include (but will not be limited to) sulfides/selenides (Cu2S, WSe2, SnS,Se, FeS2, CZTS and other kesterites,), nitrides (Zn(Ge, Si,Sn)N2, Cu3N) phosphides (ZnSnP2, Zn3P2), oxides (ZnVO, ZnSnO, Cu2O), and related multinary compounds and devices.
