Polycrystalline Thin Film Photovoltaics: From the Laboratory to Solar Fields
The conclusions of this report are that: (1) many issues how thin-film solar cells work remain unresolved, requiring further fundamental R and D effort; (2) commercial thin-film PV module production reached 29% in 2005 in the US, indicating much more rapid growth than crystalline Si PV; (3) commercial module performance is increasing based on current knowledge, more R and D will lead to further improvement; and (4) stability of thin-film modules is acceptable ({le} 1% per year power loss) if the right manufacturing processes are used for manufacturing.

Recent Analysis of UCAPs in Mild Hybrids
This report presents the analysis of ultracapacitors for mild/moderate hybrid electric vehicle (HEV) performance. The objectives of this report are to: (1) review the fuel economy improvement trends of today's HEVs with respect to degree of hybridization; (2) perform analysis to see the extent of fuel economy improvement possible with various strategies in mild/moderate HEVs, with no engine downsizing, using either batteries or ultracapacitors; (3) identify energy requirements of various driving events/functions--what matches a limited ucap's energy; and (4) discuss potential roles for high-voltage ultracapacitors in HEVs, if any.

The potential for clean energy production using oxy-fuel combustion and integrated pollutant removal
Effective remediation of flue gas produced by an oxy-fuel coal combustion process has been proven at bench scale in the course of cooperative research between USDOE’s Albany Research Center (ARC) and Jupiter Oxygen Corporation. All combustion gas pollutants were captured, including CO2 which was compressed to a liquefied state suitable for sequestration. Current laboratory-scale research and the future of combined oxy-fuel/IPR systems are discussed.

Unlikely Combination of Experiments with a Novel High-Voltage CIGS Photovoltaic Array
The goals of this study are to: (1) parameterize current-voltage (I-V) performance over a wide range of illumination and temperatures: (a) 50-1150 W/m{sup 2} irradiance, 5-65 C; (b) obtain array temperature coefficients; and (c) quantify energy production; (2) investigate high-voltage leakage currents from the CIS modules in a high-voltage array: determine dependence on moisture, temperature, and voltage bias and ascertain corrosion problems if any; and (3) study long-term power and energy production stability.
