    摘要: A photoelectric conversion device with low resistance loss and high conversion efficiency is provided. The photoelectric conversion device includes a first silicon semiconductor layer and a second silicon semiconductor layer between a pair of electrodes. The first silicon semiconductor layer is provided over one surface of a crystalline silicon substrate having one conductivity type and has a conductivity type opposite to that of the crystalline silicon substrate, and the second silicon semiconductor layer is provided on the other surface of the crystalline silicon substrate and has a conductivity type which is the same as that of the crystalline silicon substrate. Further, the first silicon semiconductor layer and the second silicon semiconductor layer each have a carrier concentration varying in the film thickness direction.

    摘要: A class D amplification device that prevents beats caused by switching operations of a switching power supply and a class D amplifier from causing noise within a voice band, enables easy control over power supply operations, and offers low power loss is provided. The amplification device includes a unit that generates a reference clock, a switching power supply that operates at a first frequency at which the frequency of the reference clock is divided, and a triangular wave generation unit that operates at a second frequency higher than the first frequency at which the frequency of the reference clock is divided. The amplification device further includes a class D amplifier that performs a switching operation with a pulse whose width has been modulated according to the input signal.
