Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
Organometal halide perovskite-based solar cells have recently realized large conversion efficiency over 15% showing great promise for a new large scale cost-competitive photovoltaic technology. Using impedance spectroscopy measurements we are able to separate the physical parameters of carrier transport and recombination in …
