   Sammanfattning : The main source of our energy system, the fossil fuels, will eventually be depleted and also pose environmental and climate hazards. There is thus a need for alternative, renewable energy sources. Solar (photovoltaic) cells will play an important role as one of them. LÄS MER

7. 25. Organic Hole Transport Materials for Solid-State Dye-Sensitized and Perovskite Solar Cells

   Författare :Jinbao Zhang; Erik Johansson; Gerrit Boschloo; Anders Hagfeldt; Nick Vlachopoulos; Ellen Moons; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectrochemical polymerization; PEDOT; dye; hole transport material; small molecule; perovskite solar cell;

   Sammanfattning : Solid-state dye-sensitized solar cells (ssDSSCs) and recently developed perovskite solar cells (PSCs) have attracted a great attention in the scientific field of photovoltaics due to their low cost, absence of solvent, simple fabrication and promising power conversion efficiency (PCE). In these types of solar cell, the dye molecule or the perovskite can harvest the light on the basis of electron excitation. LÄS MER
