Abstract
PURPOSE:To obtain very high efficiency by making each photoelectric transducer layer absorb approx. the same number of photons in a laminated element of the plurality of p-n junction type photoelectric transducer layers. CONSTITUTION:A p type GaAs layer 32, a p<+> GaAs layer 33, an n<+> type InGaP layer 34, an n type InGaP layer 35 and a p InGaP layer 36 are consecutively formed in this order. Photons having energies exceeding 1,89eV is absorbed in an InGaP photoelectric transducer layer in the surface side and photons with energies 1.43-1.89eV are absorbed by a GaAs photoelectric transducer layer at the inside because the forbidden band width of GaAs is 1.43eV while the forbidden width of InGap is 1.89eV. Therefore, the number of photons absorbed by the GaAs photoelectric transducer layer is almost equal to that absorbed by the InGaP photoelectric transducer layer thereby facilitating a very high efficiency.
