Advanced Models and Controls for Prediction and Extension of Battery Lifetime

Description: Predictive models of capacity and power fade must consider a multiplicity of degradation modes experienced by Li-ion batteries in the automotive environment. Lacking accurate models and tests, lifetime uncertainty must presently be absorbed by overdesign and excess warranty costs. To reduce these costs and extend life, degradation models are under development that predict lifetime more accurately and with less test data. The lifetime models provide engineering feedback for cell, pack and system… more

Calcium Based Test Method for Evaluation of Photovoltaic Edge-Seal Materials

Description: Because of the sensitivity of some photovoltaic devices to moisture-induced corrosion, they are packaged using impermeable front- and back-sheets with an edge seal to prevent moisture ingress. Evaluation of edge seal materials can be difficult because of the low permeation rates involved and/or non-Fickian behavior. Here, using a Ca film deposited on a glass substrate, we demonstrate the evaluation of edge seal materials in a manner that effectively duplicates their use in a photovoltaic applic… more

Clean Energy Manufacturing: U.S. Competitiveness and State Policy Strategies

Description: The capital intensive nature of clean energy technologies suggests that manufacturing clean energy equipment has the potential to support state and local economic development efforts. However, manufacturing siting decisions tend to be complex and multi-variable decision processes that require in-depth knowledge of specific markets, the logistical requirements of a given technology, and insight into global clean tech trends. This presentation highlights the potential of manufacturing in supporti… more

Energy Sector Vulnerability to Climate Change: Adaptation Options to Increase Resilience

Description: The U.S. Department of Energy is conducting an assessment of vulnerabilities of the U.S. energy sector to climate change and extreme weather. Emphasizing peer reviewed research, it seeks to quantify vulnerabilities and identify specific knowledge or technology gaps. It draws upon a July 2012 workshop, ?Climate Change and Extreme Weather Vulnerability Assessment of the US Energy Sector?, hosted by the Atlantic Council and sponsored by DOE to solicit industry input.

How Standards Control Module Design for Better or Worse

Description: One would hope that PV modules are designed for survival in the outdoors. However, it appears that some module types are really designed to pass the qualification (IEC 61216/61646) and safety (IEC 61730 and UL 1703) tests. While this has resulted in an overall increase in module reliability and a reduction in infant mortality, it may not result in the most cost-effective solution for long-term reliability and minimum power degradation. This paper will provide several examples of module types an… more
