Abstract
A stacked photovoltaic apparatus capable of improving the output characteristics is provided. This stacked photovoltaic apparatus comprises a second power generation unit including a second semiconductor layer having a first refractive index and a third semiconductor layer of an amorphous semiconductor functioning as a photoelectric conversion layer, an intermediate layer formed between a first power generation unit and the second power generation unit with a second refractive index and a reflection promotive layer formed between the intermediate layer and the second power generation unit with such a third refractive index that the difference between the third refractive index and the first refractive index is larger than the difference between the second refractive index and the first refractive index.
