Abstract:
1. A method of manufacturing a photoelectric conversion device, comprising the steps of: irradiating a first single crystal semiconductor layer with a laser beam to form an unevenness on a surface of the first single crystal semiconductor layer, wherein the first single crystal semiconductor layer is provided over a first electrode with a first impurity semiconductor layer interposed therebetween; forming an amorphous semiconductor layer on the first single crystal semiconductor layer after irradiating the first single crystal semiconductor layer with the laser beam; performing heat treatment for solid phase growth of the amorphous semiconductor layer so that a second single crystal semiconductor layer is formed; forming a second impurity semiconductor layer having a conductivity type opposite to a conductivity type of the first impurity semiconductor layer at a surface side of the second single crystal semiconductor layer; and forming a second electrode over the second impurity semiconductor layer.
