This Powerpoint presentation examines battery thermal management using PCM and concludes excellent performance in limiting peak temperatures at short period extensive battery use; although, vehicle designers will need to weigh the potential increase in mass and cost associated with adding PCM against the anticipated benefits.

Study of stability issues of TCOs for thin-film PV, including degradation of optical, electrical, and structural properties of TCOs in damp heat and required encapsulation to prevent moisture egress.

The imaging techniques enable the possibility of higher-level quality control and defect analysis of solar cell materials in in-line production processes.

Slide presentation to EVS-23 conference describing NREL work to help identify appropriate requirements for batteries to be useful for plug-in hybrid-electric vehicles (PHEVs). Suggested requirements were submitted to the U.S. Advanced Battery Consortium, which used them for a 2007 request for proposals. Requirements were provided both for charge-depleting mode and charge-sustaining mode and for high power/energy ratio and hige energy/power ration batteries for each (different modes of PHEV operation), along with battery and system level requirements.

Study of PV module encapsulation materials, processing, and testing shows that overall module reliability is determined by all component materials and processing factors.

This research provides a systematic review and harmonization of the life cycle assessment (LCA) literature of electricity generated from conventionally produced natural gas. We focus on estimates of greenhouse gases (GHGs) emitted in the life cycle of electricity generation from conventionally produced natural gas in combustion turbines (NGCT) and combined-cycle (NGCC) systems. A process we term "harmonization" was employed to align several common system performance parameters and assumptions to better allow for cross-study comparisons, with the goal of clarifying central tendency and reducing variability in estimates of life cycle GHG emissions. This presentation summarizes preliminary results.

An overview of the benefits and applications of microinverters and DC power optimizers in residential systems. Some conclusions from this report are: (1) The impact of shade is greater than just the area of shade; (2) Additional mismatch losses include panel orientation, panel distribution, inverter voltage window, soiling; (3) Per-module devices can help increase performance, 4-12% or more depending on the system; (4) Value-added benefits (safety, monitoring, reduced design constraints) are helping their adoption; and (5) The residential market is growing rapidly. Efficiency increases, cost reductions are improving market acceptance. Panel integration will further reduce price and installation cost. Reliability remains an unknown.

NREL and NASA developed a thermal-electrical model that resolves PTC and cell behavior under external shorting, now being used to evaluate safety margins of battery packs for spacesuit applications.

Presentation that reviews reliability issues related to various types of photovoltaic tecnnologies, including crystalline silicon, thin films, and concentrating PV.

"Break-even cost" for photovoltaic (PV) technology is defined as the point where the cost of PV-generated electricity equals the cost of electricity purchased from the grid. Break-even cost is expressed in $/W of an installed system. Achieving break-even cost is a function of many variables. Consequently, break-even costs vary by location and time for a country, such as the United States, with a diverse set of resources, electricity prices, and other variables. In this presentation, we introduce an analysis of PV break-even costs for residential customers in the United States, including an evaluation of some of the key drivers of PV breakeven both regionally and over time. This presentation includes our methodology and presents results for both near-term residential breakeven costs(2009) and future market sensitivities of break-even costs (2015). See also the the report "Break-Even Cost for Residential Photovoltaics in the United States: Key Drivers and Sensitivities". Presentation for NREL/TP-6A2-45991.
