Odersun

Odersun was a German photovoltaic technology company established in 2002 and headquartered in Frankfurt an der Oder. Its principal activity was the development and manufacture of flexible thin-film solar cells and modules based on copper indium gallium selenide, commonly known as CIGS. Unlike conventional rigid photovoltaic panels, Odersun's technology deposited the semiconductor layer onto a flexible copper backing, allowing the resulting modules to be shaped and integrated into architectural structures. The company positioned its products for building-integrated photovoltaics rather than only for conventional utility-scale or rooftop installations. Its modules could be cut, interconnected, and assembled into different formats for uses including building façades, roofs, canopies, and louvers. This approach connected photovoltaic generation with architectural design and potentially enabled solar installations where rigid framed modules were unsuitable. Odersun operated production, research, and management activities in Frankfurt an der Oder, Fürstenwalde, and Berlin. At its height, it employed more than 320 people across these locations. The company also worked with AT&M, described as a partner and investor, on the establishment of a joint venture in Beijing, indicating an effort to extend its manufacturing or commercial presence into China. The company received recognition in the European clean-technology sector when it led the inaugural Guardian and Library House CleanTech 100 list in 2008. This recognition reflected the perceived promise of flexible CIGS technology during a period when investors and policymakers were showing strong interest in new photovoltaic manufacturing methods. Odersun was ultimately unable to sustain its business financially. It entered administration on 1 June 2012 and filed for bankruptcy. The insolvency ended the company's operation as an independent photovoltaic manufacturer. Available reference material does not establish the precise financial causes, ownership structure, or disposition of its technology and facilities after the bankruptcy, so those details remain unspecified.

Odersun was founded in Germany in 2002 as a photovoltaic technology company focused on thin-film solar cells. Its principal technical proposition was a flexible CIGS cell manufactured on a copper substrate. CIGS, or copper indium gallium selenide, is a semiconductor material used to convert sunlight into electricity. By depositing the active layer onto copper tape rather than building the product around a conventional rigid panel structure, Odersun developed a platform intended to support lightweight and adaptable photovoltaic modules. The company's manufacturing process was described as proprietary and patented. After the thin-film semiconductor was deposited, the material could be cut and interconnected before being assembled into modules in forms suited to particular applications. This manufacturing concept supported Odersun's emphasis on building-integrated photovoltaics, in which solar-generation equipment is incorporated into the structure or envelope of a building. The company identified applications including façades, roofs, canopies, and louvers. Its technology therefore addressed both electricity generation and architectural integration, rather than treating solar modules solely as add-on equipment. Odersun maintained production, research, and management operations in Frankfurt an der Oder, Fürstenwalde, and Berlin. The company employed more than 320 people across these activities. Its presence in eastern Germany made it part of the country's broader effort to develop domestic renewable-energy and photovoltaic manufacturing capabilities. The available reference material does not provide a complete account of its financing, product sales, manufacturing capacity, or customer base, and those aspects should not be inferred from its technology description alone. The company also pursued international cooperation. In association with AT&M, identified as a partner and investor, Odersun was setting up a joint venture in Beijing, China. This initiative indicates that the company sought to build a commercial or production relationship in the Chinese market, although the available material does not establish whether the joint venture became fully operational, its ownership percentages, or its eventual outcome. Odersun received sector recognition in 2008 when it topped the inaugural Guardian and Library House CleanTech 100 list. The list presented companies considered notable within European clean technology, and Odersun's ranking reflected the attention given at the time to flexible thin-film photovoltaics and building-integrated solar systems. The company's later history ended in insolvency. Odersun went into administration on 1 June 2012 and filed for bankruptcy. The reference material characterizes the company as insolvent but does not specify a detailed breakdown of the causes, such as production costs, market conditions, financing constraints, or competition. It also does not document a successor company, an acquisition, or the later ownership of its intellectual property. Odersun is consequently best described as a defunct German photovoltaic company whose principal historical contribution was the development and attempted commercialization of flexible copper-backed CIGS modules for architectural applications.

  Company founded

  [1]Odersunen.wikipedia.org

  Odersun was established in Germany as a photovoltaic technology company focused on thin-film solar cells.

Odersun focused on flexible, building-integrated photovoltaic technology, differentiating its products from conventional rigid solar panels through the use of CIGS semiconductor layers deposited on copper tape.

• Thin-film photovoltaic cells

  Flexible CIGS solar cells

  Odersun developed photovoltaic cells using a copper indium gallium selenide semiconductor deposited as a thin layer on copper tape. The flexible backing distinguished the cells from conventional rigid photovoltaic formats and was intended to support lighter, more adaptable solar products.

• Photovoltaic modules

  Flexible photovoltaic modules

  The company converted its flexible CIGS cell material into modules by cutting, interconnecting, and assembling the cells into application-specific formats. The modules were designed for integration into façades, roofs, canopies, and louvers, allowing solar generation to be incorporated into architectural structures.
