Abstract: An organic photoelectric conversion device includes first and second organic photoelectric conversion elements which convert light into electrical energy. The first and second organic photoelectric conversion elements are disposed to be stacked in this order along an incident direction of the light. The first organic photoelectric conversion element includes a first element main body including a first substrate, first and second transparent electrodes, and an organic photoelectric conversion unit having sensitivity in a first wavelength band of the light, and a first protective film that covers the first element main body. The second organic photoelectric conversion element includes a second element main body including a second substrate, a third transparent electrode, an electrode, and an organic photoelectric conversion unit having sensitivity in a second wavelength band of the light, and a second protective film that covers the second element main body.

Abstract: A blood glucose measurement device, a blood glucose calculation method, and a blood glucose calculation program capable of accurately measuring a blood glucose level by using light are provided. The blood glucose measurement device includes a light source 11 that outputs measurement light L1 to be input to a living body 50; a light detector 12 that detects the measurement light L1 propagated inside the living body 50 and generates a detection signal in accordance with an intensity of the measurement light L1; and a computation unit that obtains a time lag between a temporal change in a first parameter related to an oxygenated hemoglobin concentration and a temporal change in a second parameter related to a deoxygenated hemoglobin concentration based on the detection signal, and obtains the data related to the blood glucose level based on the time lag.
