摘要:
A photovoltaic cell having a transparent first substrate (61) having semiconductor electrodes (7) supporting a photosensitizing dye, a second substrate (62) having counter electrodes (4) disposed so as to face the semiconductor electrodes (7), and an electrolyte layer disposed between the semiconductor electrode (7) and the counter electrode (4); the electrolyte layer (1) being sealed by a sealing member (2) lying between the first substrate (61) and the second substrate (62); the first substrate (61), the second substrate (62) and the sealing member (2) being formed of similar materials, and the portions of the first substrate and the second substrate that are in contact with the sealing member (2) being ultrasonically welded to the sealing member. This photovoltaic cell can maintain excellent cell performance for a long time.
摘要:
A semiconductor device has VMOS transistors and VMOS dynamic memory cells which are formed on the same semiconductor substrate of a first conductivity type. A buried layer of the opposite conductivity type is formed between the substrate and an epitaxial layer having V-grooves for the VMOS dynamic memory cells. In the buried layer are formed buried layers of the first conductivity type serving as sources and capacitors for the VMOS dynamic memory cells.
