Making Most of the Absorbed Photon: New Insights into Carrier Multiplication in Semiconductor Nanostructures

submitted by: RASEIBoulder
Carrier multiplication (CM) or multiexciton generation (MEG) is a process whereby absorption of a single photon produces multiple electron-hole pairs (excitons). CM could benefit a number of solar-energy conversion technologies, most notably photocatalysis and photovoltaics. This presentation overviews recent progress in understanding of the CM process in semiconductor nanocrystals, motivated by an outstanding challenge in this field - the lack of capability to quickly discern between...

Excitons and Plasmons in Nanoscale Systems

Summary: Due to growing populace and standard of living, many terawatts of energy will be needed in the near future. The sun is the largest source of carbon-neutral and renewable energy that we have available and it is the only source that can provide terawatts of energy without depleting rapidly or causing major environmental and climate concerns. To fulfill this role, revolutionary approaches to solar energy conversion are needed that provide energy at very high efficiency at very low...

Larry Kazmerski, National Renewable Energy Laboratory Solar energy from photovoltaic devices has been around since the early days of the space race, but historically has not had a substantial impact on our global energy scheme. Is that now changing? Dr. Larry Kazmerski is the executive director of Science & Technology Partnerships at the National Renewable Energy Laboratory (NREL) in Golden, CO. He has worked at NREL for over 30 years and was previously the director of the National...

Summary: The sun is a boundless source of clean energy, but it goes down every night. We and many others are trying to design solar-driven molecular machines that could be used on a global scale to store solar energy by splitting water into its elemental components, hydrogen and oxygen. Hydrogen is a clean fuel that could be used directly or combined with carbon dioxide to produce methanol, a liquid fuel. We are working on rugged light absorbers and catalysts made from Earth abundant...
