The Femtosecond Energy Diffusion Sensor: A Non-contact Tool for Photovoltaic Characterization


The femtosecond energy diffusion sensor is presented as a non-contact tool for the use in the characterization of thin film hydrogenated amorphous silicon (a-Si:H) photovoltaic cells. The sensor is based on the pump-probe technique and when used with the appropriate models, this non-contact, non-destructive tool is shown to be capable of measuring important… (More)
