Heterogeneous networks of actors including a mixed spectrum of many and diverse academic, economic, and governmental agencies combine to achieve innovations. Is there any role for innovation policy beyond influencing framework conditions in such a situation? The article analyzes the case of a successful innovation in the energy sector: photovoltaics. It argues that - given the special characteristics of the energy sector - successful innovation depended on strong political support and an advocacy coalition, which achieved institutional backing. The method chosen to realize the innovation was the creation of a niche market with the help of regulatory instruments.enTechnische Universität DortmundScience, Technology & Innovation Studies300330article (journal)
