This presentation addresses the current state of wind energy technology in the United States.

PV modules must provide mechanical support for the cells, protect the world from the voltages inside, protect the cells, diodes and interconnects from the weather outside, couple as much light as possible into the PV cells and minimize the temperature increase of the cells. The package must continue to serve these functions for at least 25 years as that is the typical module warranty period today. Furthermore the package must do all this for as low a cost as possible since the key to large scale PV growth is a reduction in cost while retaining excellent module reliability and durability. This paper will review current module construction practices for both crystalline silicon and thin film PV with emphasis on explaining why the present designs and materials have been selected. Possible long term issues with today's designs and materials will be discussed. Several proposed solutions to these issues will be presented, highlighting the research efforts that will be necessary in order to verify that they can cost effectively solve the identified issues.

This presentation describes a battery optimization and trade-off analysis for Li-ion batteries used in EVs and PHEVs to extend their life and/or reduce cost.

In many commercial cells, long tabs at both cell sides, leading to uniform potentials along the spiral direction of wound jelly rolls, are rarely seen because of their high manufacturing cost. More often, several metal strips are welded at discrete locations along both current collector foils. With this design, the difference of electrical potentials is easily built up along current collectors in the spiral direction. Hence, the design features of the tabs, such as number, location and size, can be crucial factors for spiral-shaped battery cells. This paper presents a Li-ion battery cell model having a 3-dimensional spiral mesh involving a wound jellyroll structure. Further results and analysis will be given regarding impacts of tab location, number, and size.

The presentation introduces the various types of CPV technologies and provides a status report of today's CPV companies. Six different architectures of multijunction cells are shown to near or surpass 40% in efficiency. The design space for CPV is quite complex, which is a curse for those trying to narrow it down for the first prototype, but a blessing for those who want multiple pathways for product improvement in coming years.

Presentation on step-stress accelerated degradation testing (SSADT) for photovoltaics (PV). Developed are a step-stress degradation test (SSADT) for PV reliability tests and a lifetime prediction model for PV products.

Presentation about federal fleet data, working with the federal government, and results from a survey of Clean Cities coordinators about their experiences with regulated fleets.

NREL collaborates with industry, universities, and other national laboratories as part of the DOE integrated Energy Storage Program to develop advanced batteries for vehicle applications. Our efforts are focused in the following areas: thermal characterization and analysis, evaluation of thermal abuse tolerance via modeling and experimental analysis, and implications on battery life and cost. Our activities support DOE goals, FreedomCAR targets, the USABC Tech Team, and battery developers. We develop tools to support the industry, both through one-on-one collaborations and by dissemination of information in the form of presentations in conferences and journal publications.
