Bosch Solar Energy - Structure and Products

Structure and Products

Bosch Solar Energy is subdivided into four different divisions according to product groups. The various subsidiaries are responsible to these divisions:

• SRS Silicon Recycling Services The Bosch Solar Energy subsidiary SRS Silicon Recycling Services, Inc., specialises in the recycling of silicon. The scope of the ersol Group subsidiary currently covers: silicon for solar and semiconductor applications, metallurgical grade silicon and support products. All grades of silicon.

• Bosch Solar Wafers Bosch Solar Wafers GmbH is a specialist manufacturer of monocrystalline ingots and wafers. The Bosch Solar Energy subsidiary currently produces the following products:

• Monocrystalline silicon ingots

(p- and n-type)

• Monocrystalline silicon wafers

(p- and n-type)

• Crystals and wafers with special twin structure.

• Solar Cells produces solar cells in the format 156 mm x 156 mm and is the core business sector. At a thickness of 200 µm and less, the average efficiency of monocrystalline ersol solar cells is around 17%. The share of production dedicated to higher-grade monocrystalline cells compared to multicrystalline solar cells is increasing and currently stands at about 80%. The parent company Bosch Solar Energy AG is responsible for production at its plants in Erfurt and Arnstadt.
• Bosch Solar Modules is accountable for all group activities relating to the production and sale of solar modules. The division incorporates Erfurt-based Bosch Solar Thin Film GmbH, which is devoted to the production of thin-film solar modules and achieves significant savings in the raw material silicon with the aid of thin-film technology. In addition, ersol markets crystalline solar modules from solar cells produced by ersol and other manufacturers through its Erfurt-based trading subsidiary Bosch Solar Modules GmbH. The division also has a crystalline module production line at the planning stage.
