Dr. Pablo Aitor Postigo (Instituto de Micro y Nanotecnología (Centro Nacional de Microelectrónica) PTM, calle Isaac Newton 8, 28760 Tres Cantos, Madrid, Spain)

In this talk I will describe the work of my group at IMN (Institute of Micro and Nanotechnology, CSIC) in Madrid, Spain. I will show some examples of how nanotechnology and photonics can work together (Nanophotonics) and the advantages we have found in this combination. Specifically I will present results on the first room-temperature thresholdless laser made by combing photonic crystals and quantum dots. I will also show some examples of opto-nanofluidic devices for biosensing applications and optical sensors based on Fano resonances using gold nanowires. Finally I will talk about future...

P3HT is one of the most studied -conjugated polymers from the beginning of realistic polymeric photovoltaic research and development history. There are already numbers of alternative polymers with which significantly higher PCE can be obtained. However, clear understanding about the internal relation between the number of incident photons and extracted electrons is still sparse. Especially the initial electron transfer process to bridge exciton dissociation and charge carrier formation is still controversial mainly due to its ultra-fast and complex nature. Therefore we have performed another...
