  • Photovoltaic cell and photovoltaic module employing the same
    Patent number: 7858873
    Abstract: There is provided a photovoltaic cell, which comprises: a photo-electric conversion layer having a front surface and a rear surface, and a reflection layer provided on the rear surface of the photo-electric conversion layer, wherein the reflection layer includes plural types of transparent layers having different refractive indices and alternately stacked and, when light is incident from the front surface of the photo-electric conversion layer, reflects a part of the incident light having a predetermined wavelength back into the photo-electric conversion layer.
    Type: Grant

  • Stacked photoelectric conversion device
    Patent number: 6825408
    Abstract: A stacked photoelectric conversion device comprising at least two photoelectric conversion element layers sandwiched between a first electrode layer and a light receiving second electrode layer, and at least one intermediate layer sandwiched between any two of said at least two photoelectric conversion element layers, wherein the intermediate layer has uneven surfaces on a light receiving side and a light outgoing side, the uneven surface on the latter having a greater average level difference than that on the former.
