摘要： A photoelectric conversion device has a structure in which a plurality of crystalline semiconductor particles (3) of one conductivity type each of which has a semiconductor portion (4) of the opposite conductivity type on its surface are joined to a substrate 1 serving as a lower electrode. The substrate (1) and the semiconductor portion (4) are disposed in a state of being separated by a separation portion (6). An insulator (2) is formed between the adjoining crystalline semiconductor particles (3) so as to cover the surface of the substrate (1) and the lower part of the semiconductor portion (4) and so as to expose the upper part of the semiconductor portion (4). An upper electrode (5) is formed so as to cover the insulator (2) and the upper part of the semiconductor portion (4). A short circuit between the upper electrode (5) and the substrate (1) serving as a lower electrode which is caused by the semiconductor portion (4) can be prevented by providing the separation portion (6). Therefore, the photoelectric conversion device can have high conversion efficiency and high productivity.
