Data centers are driving the development of next-generation photonic technologies with the promise of higher performance at lower cost. Worldwide research encompasses multi- and single-mode links, all-photonic switching and routing technologies, and hybrid networks combining electrical and optical switching. 

Renewable and ultra-low emissions and high efficiency energy conversion systems will be required to introduce energy resource and environmental sustainability. Next generation power systems must be designed for dynamic dispatch to complement the intermittencies of renewable power, which must be increasingly utilized. The complex interactions of the heat transfer, chemistry, electrochemistry, and fluid dynamics must be considered in the design and control of dispatchable power systems such as gas turbine, fuel cell and hybrid fuel cell gas turbine systems.

Solar cells based on the perovskite-structured light absorber CH3NH3PbI3 have recently emerged at the forefront of solution-processable photovoltaic devices, with power conversion efficiencies as high as 20.1% having now been certified. In this presentation, I will discuss our research group’s work in the area of perovskite solar cells. Our early work demonstrated that room temperature solution-processing techniques can be used to prepare devices on flexible substrates while retaining excellent power conversion efficiencies.

Printed opto-electronics is a new technology envisioning the fabrication of opto-electronic devices using printing methodologies. In this presentation I will describe the materials synthesis, development, and process engineering enabling the fabrication of unconventional opto-electronic devices, such as circuits and solar modules, all on flexible foils using several new materials.1-3 Examples of unconventional electronic materials include organic small molecular and polymeric semiconductors, metal chelates and complexes, and hybrid organic-inorganic metal oxides.

The answer is: Relieve driver developers from doing power management. Non-CPU devices on a modern system-on-a-chip, ranging from accelerators to I/O controllers, account for a significant portion of the chip area. It is therefore vital for system energy efficiency that idle devices can enter a low-power state while still meeting the performance expectation. This is called device runtime power management for which individual device drivers in commodity OSes are held responsible today.

Federal programs are subsidizing deployments of smart grid elements to promote renewable energy. But for these initial deployments to grow, the smart grid needs to become self sustaining. This will require modifications in system operations that create a level field for both reliable and renewable power. Two such modifications are proposed, founded on the concept of risk-limiting dispatch, and realized in a way that permits incremental deployment. The current practice of worst-case dispatch assumes reliable power sources and limited information.

This conference will bring influential members of the climate-change debate to UCSB in order to provoke critical thought about the dilemma at hand. This full-day event, featuring 3 panels addressing grassroots, business, and legislative solutions, respectively, comes in the wake of the UN Climate Conference in Copenhagen, Denmark. The event has been organized by students, and was conceived by a group of 23 undergraduates who were inspired to bring change to their campus community after attending the UN summit in December 2009.
