    摘要: An optical sensor includes a support layer, a thermoelectric conversion material portion disposed on the support layer and including a strip-shaped first material layer that converts thermal energy into electrical energy and a strip-shaped second material layer that is electrically conductive, and a light absorbing film disposed on the thermoelectric conversion material portion to form a temperature difference in a longitudinal direction of the first material layer. The first material layer includes a first region and a second region. The second material layer includes a third region and a fourth region connected to the second region. The optical sensor further includes a first electrode electrically connected to the first region, and a second electrode disposed apart from the first electrode and electrically connected to the third region. The first material layer has a width, perpendicular to the longitudinal direction, of 0.1 μm or more.

    摘要: An optical sensor includes a support layer, a thermoelectric-conversion material section disposed on the support layer and including strip-shaped p-type material layers configured to convert thermal energy into electric energy and strip-shaped n-type material lavers configured to convert thermal energy into electric energy, a heat sink, a light absorbing film, and an insulating film disposed between the thermoelectric-conversion material section and the light absorbing film. Each of the p-type material layers includes a first region overlapping the heat sink and a second region overlapping the light absorbing film. Each of the n-type material layers includes a third region overlapping the heat sink and a fourth region overlapping the light absorbing film. The p-type material layers and the n-type material layers are alternately disposed in series. The light absorbing film includes 60 mass % to 95 mass % of carbon and 5 mass % to 40 mass % of a resin.

    摘要: An optical sensor includes a support and a thermoelectric-conversion material section including first material layers, second material layers, and a third material layer. Each of the first material layers may have a first region including a first end portion and a second region including a second end portion. Each of the second material layers may have a third region including a third end portion and a fourth region including a fourth end portion. The first region and the second region are electrically connected to the third region and the fourth region, respectively, such that the plurality of first material layers and the plurality of second material layers are alternately connected in series to each other. The third material layer is disposed between the first region and the third region.

    摘要: A thermoelectric conversion device includes a first electrode, a thermoelectric conversion material portion containing Si and Ge as constituent elements, a conductive joining member disposed in contact with the first electrode and the thermoelectric conversion material portion and joining the first electrode and the thermoelectric conversion material portion together, and a second electrode. The Si and the Ge contain amorphous phase and crystalline phase. The joining member contains at least one of Ag, Cu, Ti, and Sn or an alloy thereof as a major constituent. The thermoelectric conversion material portion includes a first layer containing the major constituent in an amount of 10 atm % or more and in contact with the joining member, and a second layer. The second layer has a degree of crystallinity of 40% by volume to 90% by volume.
