New Way to Grow High-Efficiency Solar Cells
Continued from page 1
but they had been plagued with some important deficiencies limiting their commercial viability. It is this failure that the Los Alamos technique suc- cessfully corrects.
Reduced Bulk Defects “Characterization and modeling
attribute the improved performance to reduced bulk defects and improved charge-carrier mobility in large- grain pervoskite materials,” said Mo- hite, “and we’ve demonstrated that the crystalline quality is on par with that observed for high-quality semi- conductors like silicon and gallium arsenides.” The researchers anticipate that
their crystal growth technique will lead the field towards synthesis of wafer-scale crystalline perovskites necessary for the fabrication of high- efficiency solar-cells. In addition, the growth technique will be applicable to several other material systems plagued by polydispersity, defects and grain boundary recombination in solution-processed thin-films. The work at Los Alamos Na-
tional Laboratory was supported by a DOE Office of Basic Energy Sciences
proposal and by the Los Alamos Na- tional Laboratory Directed Research and Development (LDRD) program. This work was done in part at the Center for Integrated Nanotechnolo- gies, a DOE Office of Science User Facility. Researchers on the project include Wanyi Nie, Hsinhan Tsai, Jean-Christophe Blancon, Amanda J. Neukirch, Gautam Gupta, Jared J. Crochet, Sergei Tretiak, Hsing-Lin Wang and Aditya D. Mohite of Los Alamos, in addition to Reza Asad- pour (Purdue University), Manish Chhowalla (Rutgers Univesity) and Muhammad A. Alam (Purdue Uni- versity). Los Alamos National Laborato-
ry, a multidisciplinary research insti- tution engaged in strategic science on behalf of national security, is op- erated by Los Alamos National Secu- rity, LLC, a team composed of Bech- tel National, the University of Cali- fornia, The Babcock & Wilcox Com- pany, and URS Corporation for the Department of Energy’s National Nuclear Security Administration.

knowledge you need,” said Walt Zerbe, product manager, audio, OnQ Legrand and NuVo; and Chairman of CEA’s R10 Residential Systems Com- mittee. “CEB29 will help ensure your communicating products and the wires they connect to are installed properly and protected against light- ning, electrical surges and electrical noise generated by other devices in your home.” “As more smart grid de-
vices are connected, the impor- tance of proper installation practices grows,” said Brian Markwalter, senior VP of re- search and standards at CEA. “Although there are many sources for information on in- stallation, most of them are written for trained professionals. Those sources are narrowly focused, typi- cally addressing only a single area, so the reader must master many of them to get the complete story. CEB29 ties everything together for the installation professional.” CEB29 includes the most im-
portant installation requirements and recommendations from the Na- tional Electric Code (NEC), UL, wiring standards and other expert sources covering a wide range of sub- jects including the proper installa- tion of high- and low-voltage wiring, grounding, lightning and surge pro- tection, and many of the installation problems encountered by today’s wired, wireless and power-line carri- er networks.

serves as a compendium of stan- dards, practices, and guidelines con- sidered relevant for the development and deployment of a robust and in- teroperable Smart Grid. The Energy Independence and
Security Act of 2007 directed the Na- tional Institute of Science and Tech- nology (NIST) in 2009 to form the Smart Grid Interoperability Panel (SGIP) as a public-private partner- ship. SGIP was charged to coordinate standards work to ensure interoper- ability and security as the grid is modernized. In 2012 the SGIP transitioned
to SGIP 2.0, Inc., a member-funded organization that carried forth its predecessor’s original mission. Contact: Consumer Electronics
