Abstract:

In the last few years, the organolead halide perovskite CH3NH3PbI3 and its derivatives have been found to be very efficient light harvesters and ambipolar semiconductors revolutionizing the field of solid-state solar cells. Its low temperature fabrication process allowed to design simpler solar cell structures (i.e. from mesoscopic to planar junctions) which yielded efficiencies approaching 20%. 

We have shown that one can synthesize nanowires of this photovoltaic perovskite (Horváth et al, in Nano Letters DOI: 10.1021/nl5020684) which in association with carbon nanostructures (carbon nanotubes and graphene) makes outstanding composites with rapid and strong photoresponse. They can serve as conducting electrodes and as central components of sensors, detectors. The demonstration of the performance of several devices based on these composite structures will be given.
