Renewable Energies

The development of high-efficiency and cost-saving thin-film solar cells is in the focus of our fundamental research efforts. Compared to conventional cells based on Si-wafer technology, the thickness of light absorbing layers in thin-film cells is typically 100 times smaller. Such cells comprise novel materials, e.g., copper-indium-sulfide (CIS) and organic semiconductors, as well as already established absorbers such as silicon.

Fundamental research at the HZB aims at providing a solid knowledge-base of all processes that determine the function of solar cells, e.g., regarding the generation and transport of charges. Further targets include developing novel photovoltaic materials, cell architectures, and production processes. A related field of research at the HZB concerns solar fuels for efficient energy storage. Researchers at the HZB are committed to employ new fundamental knowledge for realizing prototype next-generation solar cells to enable innovative technologies in cooperation with industry partners.

Competence Centre PVcomB

Overview Competence Centre PVcomB

PVcomB (Competence Centre Thin-Film- and Nanotechnology for Photovoltaics Berlin) was founded in 2007 by the HZB – Helmholtz-Zentrum Berlin für Materialien und Energie GmbH (formerly HMI – Hahn-Meitner-Institut) and the TUB – Technical University Berlin. PVcomB's main goal is to support world wide growth of thin-film photovoltaic technologies and -products by providing the much needed technology transfer. The structure of PVcomB is unique in ist combination of research & development with high-level education and training. In cooperative R&D projects with industry, all relevant aspects of the production of thin-film modules are addressed. Additionally, education and training will provide the industry with highly skilled thin-film PV professionals.

Solar energy research uses a broad spectrum of technical facilities. It co-operates with various institutes and industrial companies. The goal is to offer a scientific and technological response to the growing demands and challenges of business globalisation.
