PHOTOVOLTAIC CONVERTER |
摘要 |
It is an object of the present invention to improve photoelectric conversion efficiency in a photoelectric conversion device. The photoelectric conversion device 11 according to the present invention uses a polycrystalline semiconductor layer including a plurality of semiconductor particles 3a coupled together as a light-absorbing layer 3, each of the semiconductor particles 3a including a group I-III-VI compound, each of the semiconductor particles 3a having a higher composition ratio P I of a group I-B element to a group III-B element in a surface portion thereof than that in a central portion thereof. |
