Engineers Set New World Record in Solar Cell Efficiency

A diagram of the spectrum-splitting, four-junction mini-module developed at UNSW. (Courtesy of UNSW) A new solar cell configuration developed by engineers at the University of New South Wales has pushed sunlight-to-electricity conversion efficiency to 34.5% – establishing a new world record for unfocused sunlight and nudging closer to the theoretical limits for such a device. The record was set by Dr Mark Keevers and Professor Martin Green, Senior Research Fellow and Director, respectively, of UNSW’s Australian Centre for Advanced Photovoltaics, using a 28-cm2 four-junction mini-module – embedded in a prism – that extracts the maximum energy from sunlight. It does this by splitting the incoming rays into four bands, using a hybrid four-junction receiver to squeeze even more electricity from each beam of sunlight.

Optics Breakthrough Could Revamp Night Vision

By etching grooves in the film, the light is redirected and almost all of it is absorbed. The absorbing layer is less than 1/2000th the thickness of a human hair. (Credit: Dr. Thomas P. White, Australian National University) A breakthrough by an Australian collaboration of researchers could make infrared technology easy-to-use and cheap, potentially saving millions of dollars in defense and other areas using sensing devices, and boosting applications of technology to a host of new areas, such as agriculture. Infra-red devices are used for improved vision through fog and for night vision and for observations not possible with visible light; high-quality detectors cost approximately $100,000 (including the device at the University of Sydney) and some require cooling to -200°C.

Advanced Passive Thermal Management Technologies for Power Electronics: Solutions to Reduce Noise, Power Consumption, and Operating Costs

Components housed within power electronic devices continue to shrink in size and increase in power. This trend results in high heat flux components integrated into small packages; driving the need for enhanced thermal management to ensure high performance and long life for the devices. Properly managing the thermal loads within these systems can be challenging; and traditional solutions of larger pumps and fans result in more noise and higher power consumption.

Product of the Month

Stratasys, Eden Prairie, MN, introduced the J750 3D printer that produces full-color, multi-material prototypes and parts in a single 3D print without post-processing. Users can choose from more than 360,000 different color shades plus multiple material properties ranging from rigid, to flexible and opaque, to transparent. Prototypes such as tooling, molds, jigs, and fixtures can include an array of colors, materials, and material properties in the same part. The printer is supported with PolyJet Studio™ software that allows users to choose materials, optimize the build, and manage print queues. Assignment of colors, transparencies, and rigidity is accomplished via familiar design controls. Color textures can be loaded fully intact via VRML files imported from CAD tools. Featuring a large, six-material capacity, the printer keeps the most-used resins loaded for printing.
