Multilayer photoelectric converter, multilayer photoelectric converter array, non-contact temperature measurement device, and imaging device

Abstract

A multilayer photoelectric converter includes a first photoelectric converter, and a second photoelectric converter. The first photoelectric converter and the second photoelectric converter are stacked in this order from a side of the multilayer photoelectric converter where light is incident. The first photoelectric converter has a sensitivity characteristic with a sensitivity having a peak at a wavelength λ1a. The second photoelectric converter has a sensitivity characteristic with a sensitivity having a peak at a wavelength λ2a. For the multilayer photoelectric converter, the relationship λ1a<λ2a is satisfied. The sensitivity of the second photoelectric converter at the wavelength λ2a is less than the sensitivity of the first photoelectric converter at the wavelength λ1a.
