1. 1. Exploring the Role of Business Models in Large-Scale Diffusion of Solar Photovoltaics - A study of demand-side solar firms in Sweden

   Författare :Amanda Bankel; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; firm; innovation; sustainability; Sweden; photovoltaic; business model; diffusion; solar; system; policy;

   Sammanfattning : A rapid and large-scale diffusion of renewable energy technologies, like solar photovoltaics (PV), is crucial to slow down climate change. Research on technology diffusion explains that the rate and scale at which a new technology diffuses in society is influenced by the actors, networks, and institutions that make up its innovation system.
