Colloidal Nanocrystals for solar energy conversion Andreu Cabot Catalonia Institute for Energy Research - IREC, Sant Adria del Besos, Barcelona, 08930, Spain Institució Catalana de Recerca i Estudis Avançats - ICREA Solution-based methods allow producing nanomaterials with unmatched degree of control over size, shape, phase and composition of the crystalline domains. At the same time, the availability of materials in solution or as nano-inks enables a large volume and high yield fabrication of devices over a variety of substrates by cost-effective printing and coating technologies. However solution-processing technologies are not without limitations. The presence of organic ligands, the large density of surface defects and the difficult control over the carrier concentration are three main challenges to be overcome to fabricate efficient energy conversion devices. In this talk the potential of solution-based synthesis routes and solution-processing technologies to produce low cost functional nanomaterials and films with nanometer-scale control over their composition, crystal phase, geometry and size will be discussed. I will also discuss on the advantages and limitations of these technologies to fabricate efficient energy conversion devices able to compete with current conventional technologies. I will particularly focus on the application of nanoparticles for solar energy conversion.
