A photoelectric conversion device with low resistance loss and high conversion efficiency is provided. The photoelectric conversion device includes a first silicon semiconductor layer and a second silicon semiconductor layer between a pair of electrodes. The first silicon semiconductor layer is provided over one surface of a crystalline silicon substrate having one conductivity type and has a conductivity type opposite to that of the crystalline silicon substrate, and the second silicon semiconductor layer is provided on the other surface of the crystalline silicon substrate and has a conductivity type which is the same as that of the crystalline silicon substrate. Further, the first silicon semiconductor layer and the second silicon semiconductor layer each have a carrier concentration varying in the film thickness direction.

Photoelectric conversion device

A photoelectric conversion module in which an output voltage defect is suppressed is obtained by forming in parallel over a substrate n number (n is a natural number) of integrated photoelectric conversion devices each including a plurality of cells that are connected in series, and electrically connecting in parallel n&#x2212;1 number or less of integrated photoelectric conversion devices with normal electrical characteristics and excluding an integrated photoelectric conversion device with a characteristic defect such as a short-circuit between top and bottom electrodes or a leak current due to a structural defect or the like formed in a semiconductor layer or the like.

Photoelectric conversion module and manufacturing method thereof

In reproducing a recording medium having a main data area for recording main data, an auxiliary data area for recording auxiliary data such as image data and text data corresponding to the main data, a first control area for controlling the main data area, and a second control area for controlling the auxiliary data, the auxiliary data is reproduced in a predetermined timed relation with the main data based on synchronization information recorded in the second control area.
