Patent ID: 8138499

Claim:
A stacked photoelectric conversion device comprising: a first photoelectric conversion layer, a second photoelectric conversion layer and a third photoelectric conversion layer stacked in this order from a light entrance side, each photoelectric conversion layer having a p-i-n junction and formed of a silicon based semiconductor, wherein a short-circuit photocurrent of the first photoelectric conversion layer is larger than a short-circuit photocurrent of the second photoelectric conversion layer or a short-circuit photocurrent of the third photoelectric conversion layer under a condition of light source: xenon lamp, irradiance: 100 mW/cm 2 , AM: 1.5, and temperature: 25° C., wherein a ratio of the short-circuit photocurrent of the first photoelectric conversion layer to a smaller one of the short-circuit photocurrent of the second photoelectric conversion layer and the short-circuit photocurrent of the third photoelectric conversion layer is 1.01 to 1.30.
