PHOTOELECTRIC CONVERSION DEVICE AND ENERGY CONVERSION LAYER FOR PHOTOELECTRIC CONVERSION DEVICE

摘要

The present invention provides a novel photoelectric conversion device capable of effectively utilizing light energy and capable of improving performance. A photoelectric conversion element, and an energy conversion layer located on the light-receiving surface side of the photoelectric conversion layer of the photoelectric conversion element. The energy conversion layer has a plurality of first layers and a plurality of second layers, and has a structure in which the first layer and the second layer are alternately laminated. The thickness of the plurality of first layers is 0.5 nm or more and 10 nm or less, respectively. The thickness of the plurality of second layers is 0.5 nm or more and 10 nm or less, respectively. And the second layer may have a material having a larger energy band gap than the first layer.
