Art Nozik Seminar on Third Generation Solar Cells
by Willison, Sheryl L 16 Jan '07

16 Jan '07

SEMINAR ANNOUNCEMENT Title: Carrier Dynamics and Multiple Exciton Generation in Semiconductor Nanocrystals: Applications to Third Generation Solar Photon Conversion By: A.J. Nozik, Center for Basic Sciences (National Renewable Energy Laboratory) and Department of Chemistry (University of Colorado) Location: FRNY G140, 3:30 PM, Tuesday, January 16th, 2006 Abstract: In order to utilize solar power for the production of electricity and fuel on a massive scale, it will be necessary to develop solar photon conversion systems that have an appropriate combination of high efficiency and low capital cost ($/m2). One potential, long-term approach to high efficiency is to utilize the unique properties of semiconductor quantum dot nanostructures to control the relaxation dynamics of photogenerated carriers to produce either enhanced photocurrent through efficient exciton multiplication or enhanced photopotential through hot electron transport and transfer processes. To achieve these desirable effects it is necessary to understand and control the dynamics of electron relaxation, cooling, multiple exciton generation (MEG), transport, and interfacial electron transfer of the photogenerated carriers with fs to ns time resolution. At NREL, we have been studying these fundamental dynamics in bulk and nanoscale semiconductors (quantum dots, quantum wires, and quantum wells) using femtosecond transient absorption, photoluminescence, and THz spectroscopy. This work will be summarized and recent advances in creating multiple excitons from a single photon will be discussed, including a unique model to explain efficient MEG based on the coherent superposition of multiple excitonic states. Various possible configurations for quantum dot solar cells that could produce ultra-high conversion efficiencies for the production of solar fuels and electricity will be discussed, along with associated thermodynamic calculations that show the theoretical gains in solar photon conversion efficiency for both electricity and fuel production. ________________________________ Arthur J.

Conversion to OnePurdue program
by Brown, Stacy L. 14 Jan '07

14 Jan '07

As many of you are aware, Purdue is converting to a new software program as of February 1. With this conversion the Ariba program will go away. All of you should receive notification from OnePurdue about the necessary training that will need to be taken for the new purchasing mechanism (SRM), the training will be ready the middle to end of January. As of January 26th any orders that require approvals from Purchasing need to be in Ariba. After the 26th we will not be placing any additional orders using Ariba. Please be sure that you prepare for this transisition and place orders for any items that you will need during this tranisition time before January 26th. We will still be able to place orders via credit card during this time. Please be sure to let me know if you have any questions. Thanks, Stacy

SIDEWALKS ARE OPEN
by John Weaver 12 Jan '07

12 Jan '07

THE SIDEWALKS ARE OPEN around the Birck Nanotechnology Center. Because of the lateness of the day, the contractor is opening fence panels to allow access to the sidewalks, and will return Monday to take down the fencing that will be removed at this time. Most of the fence will remain in place, but all locations where there is sidewalk access the fencing will be removed. As stated previously, the contractor will return in the Spring to complete the landscaping work. To keep our building clean - and for your own safety - please stay on the sidewalks! Thanks, John Weaver John R. Weaver Facility Manager Birck Nanotechnology Center Purdue University (765) 494-5494 jrweaver(a)purdue.edu

Extra filing space for Grad Student Offices
by Brown, Stacy L. 12 Jan '07

12 Jan '07

I wanted to let you know that on Tuesday, two drawer lateral files will be delivered for the graduate student offices. There will be furniture installers here around 10-10:30 on Tuesday morning to start installing the lateral files. There will be a total of four lateral files installed in each graduate student office. These files will be placed under the window on the back wall. Please be sure that any items that you have located under this window have been moved by Tuesday morning. Let me know if you have any questions. Thanks, Stacy Stacy Brown Purdue University Business Manager Birck Nanotechnology Center Phone: 765-494-1619 Fax: 765-496-8299

Upcoming Required NSF Grants.gov submissions
by Brown, Stacy L. 10 Jan '07

10 Jan '07

Below is an email from SPS about upcoming due dates for NSF proposals that must be submitted via Grants.gov. Please be sure that your allowing adequate time if you are submitting to one of these solicitations. Please let me know if you have any questions. Thanks, Stacy Stacy Brown Purdue University Business Manager Birck Nanotechnology Center Phone: 765-494-1619 Fax: 765-496-8299 NSF has announced it's FY 2007 Grants.gov required programs listed below: * 06-554 Antarctic Artists and Writers (OPP) -- June 6, 2007 * 07-502 Scientific Computing Research Environments for the Mathematical Sciences (MPS) -- January 25, 2007 * * 06-574 Living Stock Collections (BIO) -- July 4, 2007 * 06-535 Advanced Learning Technologies (CISE) -- April 25, 2007 * 06-584 CEDAR, GEM, and SHINE Postdoctoral Research (GEO) -- February 5, 2007 * 07-511 Research in Disability Education (EHR) - February 12, 2007 * PD 05-1635 Infrastructure Materials Applications and Structural Mechanics (ENG) -- February 15, 2007 and October 1, 2007 * PD 98-1352 Geography and Regional Science (SBE) -- January 15, 2007 and August 15, 2007 Note for the Geography and Regional Science program, the Doctoral Dissertation Research Improvement proposals are not required to be submitted through Grants.gov. * Please note NSF 07-502 Scientific Computing Research Environments for the Mathematical Sciences (MPS) program with a due date of January 25, 2007. We are anticipating that there will be some proposals in response to this solicitation. Below we have highlighted some critical issues to be aware of when preparing a NSF Grants.gov application: * All PIs, Co-PIs, and subawardee organizations must be registered Fastlane users prior to submission. Please contact SPS to establish an account if you are a new user. * NSF requires that applicants submit attachments to applications in PDF format. To avoid problems with converting files to PDF, please use the NSF Conversion Utility tool accessed through the Proposal Preparation module. * Once a proposal is submitted through Grants.gov, it must pass an electronic validation check in order to be inserted into the Fastlane system. If it fails, the proposal will have to be resubmitted through Grants.gov before the deadline. Once a proposal is accepted into Fastlane, updates, revisions or any future activity must be done through Fastlane. * A guide for preparation and submission of NSF applications via Grants.gov is available for download with each Grants.gov package. However, you will still need to look at the program solicitation for instructions specific to that solicitation or for any additional requirements. * All collaborative proposals submitted as separate submissions from multiple organizations must be submitted via the NSF FastLane system and cannot be submitted through Grants.gov. If you are preparing a NSF Grants.gov proposal, please contact SPS Pre-award Services. Attached is a more detailed explanation of the above points. <<Purdue University NSF Grants.doc>>
