Polycrystalline Silicon solar cells: Improvements in efficiency through hydrogen passivation Conference Paper uri icon


  • 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 hydrogĂ©nation. A model has been suggested explaining the experimental results. The degradation of the electrophysical properties of hydrogenated grain boundaries is observed during the electron beam irradiation in Scanning Electron Microscope (experiments" in situ"). It is shown …
