Abstract

The influence of hydrogen passivation of structural defects on the parameters of solar cells from shaped polysilicon was investigated. Various changes of the parameters of the different solar cells were found under identical conditions of hydrogenation. A model has been suggested explaining the experimental results. The degradation of the electrophysical properties of bydrogenated grain boundaries is observed during the electron beam irradiation in Scanning Electron Microscope (experiments "in situ"). It is shown theoretically that the state of hydrogen complexes may be changed due to interaction with "hot" carriers generated by the electron beam.
