  3. 3. In pursuit of next generation photovoltaics : An electronic structure study of emerging solar cell materials

    Författare :Axel Erbing; Michael Odelius; David Scanlon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solar cells; computational physics; density functional theory; electronic structure; molecular dynamics; Solceller; beräkningsfysik; täthetsfunktionalteori; elektronstruktur; molekyldynamik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : The development of a new generation of photovoltaic technologies is an important task in order to increase the production of clean energy. Perovskite solar cells, with an exceptionally rapid development over the last decade, have transformed into perhaps the most promising candidate to provide a low-cost alternative to conventional cells.
