Dr. Yeuh-Lin Loo, an Assistant Professor in Chemical Engineering, has led a team of Princeton, University of Texas – Austin, Pennsylvania State University, University of California – Santa Barbara, and Dupont researchers in developing a conductive plastic that takes the place of expensive indium tin oxide (ITO) used in solar cells, flat-screen TVs, and other electronic devices with display screens.  ITO, a byproduct of mining, is rare and expensive, but a necessity in today’s electronics.  An inexpensive substitute would be desirable in bringing costs down and removing pressure from the growing demand for ITO.  Loo comments on this in the Princeton press release.  “The cost of indium tin oxide is skyrocketing.  To bring down the costs of plastic solar cells, …

A solar cell manufacturer that boasts of 100 times thinner panels than current silicon solar cells, and production rates 100 times faster than with the methods usually employed in the industry will definitely catch our attention.   Nanosolar, of San Jose, California, makes a CIGS-based solar film claimed to be thinner and much less expenive (ultra-low cost, according to Nanosolar) than silicon-based panels.  CIGS stands for copper/indium/gallium/selenium, the primary components of the new film.  Coated onto a thin aluminum substrate, the CIGS ink is literally printed on, the nanoparticles providing a demonstrated efficiency of up to 16.4-percent, verified by the National Renewable Energy Laboratory (NREL).  Initial production runs are producing panels of at least 11-percent efficiency.  While currently only half as efficient as the best production silicon solar cells, the high-speed manufacturing …

Tolstoy, in War and Peace, wrote that, “Among the innumerable subdivisions that can be made in the phenomena of life, one can subdivide them all into those in which content predominates and those in which form predominates.” One group attempting to meld form and function is the Land Art Generator Initiative, a group attempting to “bring together artists, architects, scientists, and engineers in a first of its kind collaboration. The goal of the Land Art Generator Initiative is to design and construct a series of land art installations across the UAE that uniquely combine aesthetic intrigue with clean energy generation. The LAGI viewing platforms will be tourist destinations that draw people from around the world to experience the beauty of …
