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.

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.

Silicon Heterojunction Solar Cell Characterization and Optimization Using In Situ and Ex Situ Spectroscopic Ellipsometry
The summary of this report is that: in situ SE gives insight into growth mechanisms and accurate layer thickness; (2) ex situ SE measures completed device structures to determine integrated optical properties; and (3) the combination of in situ and ex situ SE provides a powerful method for pinpointing the effects of processing changes in actual SHJ devices and guiding optimization.
