  • Patent number: 4665278
    Abstract: A heat-resistant thin film photoelectric converter comprising a semiconductor layer, front and back electrodes, and a diffusion-blocking layer, the diffusion-blocking layer being provided between the semiconductor and at least one said electrode, and its preparation. The diffusion-blocking layer is of a metal selected from the Group IVA metals and Group VA metals of the Periodic Table. The converter avoids the reduction in efficiency due to the diffusion of metal or metallic compound from the electrode into the semiconductor.
