    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photovoltaic cells; parabolic reflectors; optical efficiency; Solar concentrators; photovoltaic-thermal systems; non-imaging optics; optical properties; building integrated photovoltaics; non uniform irradiance distribution; structured reflectors; solar cell modelling; ray tracing;

    Abstract : Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. READ MORE

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

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

    Abstract : 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.
