My research is focused on a new generation of laser-processed semiconductors for obtaining high-efficiency solar cells and far infrared detectors. I’m interested in the potential of supersaturated semiconductors with deep impurities to form intermediate band semiconductors. I work on fabricating, laser-processing and characterizing the supersaturated semiconductors to gain further understanding of the fundamental phenomena that could enhance the quantum efficiency in solar cells. I study supersaturated Si-based semiconductors to increase the efficiency detection in the far infrared region.
David received a degree in physics from Universidad Autónoma de Madrid and he completed a PhD in optoelectronics at C.S.I.C.-Universidad de Barcelona in Spain.
He worked as postdoctoral fellow on supersaturated silicon semiconductors at Universidad Complutense de Madrid and in the Solar Energy Institute at Universidad Politécnica de Madrid in Spain. He joined the Aziz group in August 2012.
