Abstract:
1. A method for manufacturing a photoelectric conversion device, comprising the steps of: forming an insulating layer over a first surface of a single crystal semiconductor substrate, introducing an ion to the single crystal semiconductor substrate through the insulating layer to form an embrittled layer in the single crystal semiconductor substrate, introducing a first impurity element into the single crystal semiconductor substrate through the insulating layer, thereby forming a first impurity semiconductor layer between the embrittled layer and the first surface of the single crystal semiconductor substrate, separating a single crystal semiconductor layer with the first impurity semiconductor layer from the single crystal semiconductor substrate at the embrittled layer, depositing a second impurity semiconductor layer on an embrittled plane side of the single crystal semiconductor layer, forming a first electrode adjacent to the second impurity semiconductor layer, selectively removing the insulating layer to retain a portion thereof in a peripheral edge portion of the first impurity semiconductor layer, and forming a second electrode in a region in which the insulating layer has been removed.
