Patent ID: 8338218

Claim:
A method for manufacturing a photoelectric conversion device module, comprising: preparing a plurality of single-crystal semiconductor substrates, wherein each of the plurality of single-crystal semiconductor substrates is provided with a first electrode and an insulating layer over one surface thereof and an embrittlement layer therein; attaching the plurality of single-crystal semiconductor substrates to a base substrate with the first electrode and the insulating layer therebetween so that the insulating layer and the base substrate are bonded, wherein the plurality of single-crystal semiconductor substrates are arranged over the base substrate with an interval therebetween; separating each of the plurality of single-crystal semiconductor substrates at the embrittlement layer as a boundary, whereby a plurality of stacked bodies in which the insulating layer, the first electrode and a first single-crystal semiconductor layer having a first conductivity type are stacked sequentially are formed over the base substrate; forming a second single-crystal semiconductor layer over the plurality of stacked bodies so as to cover the plurality of stacked bodies and a space between the plurality of stacked bodies adjacent to each other; forming a second impurity semiconductor layer having a second conductivity type opposite to the first conductivity type over the second single-crystal semiconductor layer so that a first photoelectric conversion layer in which the first single-crystal semiconductor layer, the second single-crystal semiconductor layer and the second impurity semiconductor layer are stacked is formed; forming a second photoelectric conversion layer comprising a non-single-crystal semiconductor layer over the first photoelectric conversion layer; forming a second electrode over the second photoelectric conversion layer; selectively etching the second electrode, the second photoelectric conversion layer and the first photoelectric conversion layer at the space between the plurality of stacked bodies adjacent to each other to partially expose the first electrode of each of the plurality of stacked bodies, whereby a plurality of photoelectric conversion cells are arranged over the base substrate with an interval therebetween; and forming a plurality of connecting electrodes wherein each of the plurality of connecting electrodes connects two of the plurality of photoelectric conversion cells adjacent to each other and is in contact with an upper surface of the second electrode of one of the two of the plurality of photoelectric conversion cells and an exposed upper surface of the first electrode of the other of the two of the plurality of photoelectric conversion cells.
