Goodwill [Abstract]
Goodwill Disclosure [Text Block]	Goodwill The Company's goodwill is associated with the Photovoltaics segment. As of September 30, 2010, we performed an interim goodwill impairment test which indicated that no impairment existed and that fair value exceeded carrying value by approximately 40%. As of December 31, 2010, we performed an annual goodwill impairment test which indicated that no impairment existed. As of June 30, 2011, there have been no significant changes in the underlying assumptions used to prepare this test, nor have we identified any indications of impairment or triggering events through the nine months ended June 30, 2011. However, we will continue to monitor any changes in circumstances or triggering events that might indicate impairment of our goodwill. If there is erosion of the Company's market capitalization or the Photovoltaics reporting unit is unable to achieve its projected cash flows, we may be required to perform additional impairment tests. The outcome of these additional tests may result in the recording of goodwill impairment charges.
