1. 6. Functional Materials for Perovskite Solar Cells

   Författare :Wei Zhang; Lars Kloo; Neil Robertson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; perovskite solar cell; photovoltaic device; lead-free light absorbers; hole-transport materials; coordination complexes; p-type dopants; organic salts; surface passivation.; Kemi; Chemistry;

   Sammanfattning : Energy plays a significant role in our daily lives, but most energy provided by fossil fuels causes serious environmental problems including air pollution, global warming, and ecological damage. In addition, it has been estimated that all of our fossil fuels will run out in 2088 and thus it is highly important to study and apply renewable energy sources. LÄS MER
