Source-derived summary

Energy Conversion Devices, Inc. (ECD) was an American photovoltaics manufacturer of thin-film solar cells made of amorphous silicon used in flexible laminates and in building-integrated photovoltaics. The company was also a manufacturer of rechargeable batteries and other renewable energy related products. ECD was headquartered in Rochester Hills, Michigan.

Through its wholly owned Auburn Hills, Michigan, subsidiary United Solar Ovonic, LLC, better known as Uni-Solar, ECD was at one time the world's largest producer of flexible solar panels. Uni-Solar panels consisted of long rectangular strips with wiring at one end, which could be glued to any suitable supporting surface. They were widely used on flat roofs, motorhomes, semi-trailer cabs and similar roles.

On February 14, 2012, Energy Conversion Devices, Inc. and its subsidiaries, United Solar Ovonic LLC and Solar Integrated Technologies, Inc. filed for bankruptcy in the U.S. United States District Court for the Eastern District of Michigan.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as american photovoltaics manufacturer. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 15, 2026. The linked authority identifier is Q5376911. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2012.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
