Abstract:This presentation will offer an overview of the research of Clean Energy Engineering Laboratory at Berkeley, with emphasis on the roles of semiconductor materials science and technology in the development of various energy conversion systems. The first half of the talk will be devoted to the introduction of a new-generation high throughput combinatorial materials synthesis and characterization platform dedicated to the screening of materials for thin film photovoltaic absorber and transparent conducting oxides. The second half of the talk will include a short discussion of recent progress in two semiconductor-related clean energy technologies: organic light emitting diodes and solar driven hydrogen production. The talk will end with a summary of what contributions semiconductor science and technology can play in the broader field of clean energy.
