Structure and products
Bosch Solar Energy is subdivided into four different divisions according to product groups. The various subsidiaries are responsible for these divisions:
*''SRS Silicon Recycling Services'' The Bosch Solar Energy subsidiary SRS Silicon Recycling Services, Inc., specializes 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 structures.
*''Solar Cells'' produces

line 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.
Management board
The management board of Bosch Solar Energy AG consists of four members:
*Holger von Hebel,
CEO (responsibilities: Corporate Development, Finance/Controlling, Human Resources, Corporate Communications, IT, Legal Affairs and Post Merger Integration)
*Dr. Volker Nadenau,
CTO (responsibilities: Research & Development, Process Development and Photovoltaic Strategy)
*Jürgen Pressl,
COO (responsibilities: Manufacture of Ingots, Wafers, Solar Cells, Crystalline and Thin-film Solar Modules, Purchasing/Supply Chain Management)
*Peter Schneidewind,
CSO (responsibilities: Sales, Marketing and Product Management)
