Embodiment approach 1

[0057] A photoelectric conversion device according to an embodiment of the present invention includes at least two units. The unit is composed of a single-layer structure or a laminated structure of a photoelectric conversion layer which is the smallest unit having a photoelectric conversion function. Furthermore, the photoelectric conversion device has at least one structure formed by making the fiber body contain resin, and this structure is sandwiched between the two units. refer to figure 1 Instead, the structure of a photoelectric conversion device according to one embodiment of the present invention will be described.

[0058] figure 1 The photoelectric conversion device shown includes a unit 102 (also referred to as a first unit) supported by a substrate 101 (also referred to as a first substrate), a structure 103, and a substrate 104 (also referred to as a second substrate). Supported unit 105 (also called second unit). A structure 103 is interposed between the uni...

Embodiment approach 2

[0119] In this embodiment, with Figure 2A The shown photoelectric conversion device is used as an example to explain the method of manufacturing the disclosed photoelectric conversion device of the present invention.

[0120] First, the formation of the cell 102 on the substrate 101 will be described. Such as Figure 6A As shown, a patterned (processed into a predetermined shape) conductive film 110 is formed on a substrate 101 . In this embodiment mode, a photoelectric conversion device in which light is incident from the side of the substrate 101 is described as an example, so it is preferable that the substrate 101 has light transmittance to visible light. As the substrate 101, for example, various commercially available glass plates such as soda lime glass, opaque glass, lead glass, tempered glass, ceramic glass, and the like can be used. In addition, non-alkali glass substrates such as aluminosilicate glass, barium borosilicate glass, aluminoborosilicate glass; quartz...

Embodiment approach 3

[0165] In this embodiment mode, a structure in which a unit having a photoelectric conversion layer is formed and adhered to a plastic substrate (substrate having flexibility) will be described. Specifically, the following configurations are exemplified. In this structure, after the peeled layer including the photoelectric conversion layer is formed on a support substrate with high heat resistance such as glass or ceramics with a peeling layer and an insulating layer interposed therebetween, the support substrate and the peeled layer are separated from each other by the peeling layer. Separated, the separated peeled layer is bonded to a plastic substrate to form a unit on the plastic substrate. In this embodiment, the manufacture of a cell (bottom cell) disposed on the side opposite to the light incident side will be described. When a cell formed by the manufacturing method described in this embodiment is used as a cell (top cell) disposed on the light incident side, the stac...

Abstract

An object is to provide a photoelectric conversion device whose mechanical strength is increased without complicating a manufacturing process. The photoelectric conversion device includes a first cell having a photoelectric conversion function, a second cell having a photoelectric conversion function, and a structure body including a fibrous body which firmly attaches the first cell and the second cell. As a result, p-i-n junctions are bonded with the structure body in which the fibrous body is impregnated with an organic resin, which is a so-called prepreg. Thus, a photoelectric conversion device whose mechanical strength is increased can be realized while the manufacturing cost is reduced.

Description

technical field [0001] The present invention relates to a photoelectric conversion device capable of generating electric energy by using light and a manufacturing method of the photoelectric conversion device. Background technique [0002] A solar cell is a photoelectric conversion device that uses the photovoltaic effect to directly convert received light into electricity and output it. Unlike conventional power generation systems, those using solar cells do not need to convert energy into heat or kinetic energy in the process. Therefore, although fuel is consumed when producing or installing a solar cell, etc., the solar cell has an advantage that the emission of a greenhouse effect gas typified by carbon dioxide per unit of electricity generated by the solar cell, exhaust gas containing toxic substances, is higher than that of energy based on fossil fuels. much less. In addition, the light energy that the sun shines on the earth for one hour is equivalent to the energy ...
