Problems solved by technology
[0007] However, in this case, since the area of the solar cell module irrelevant to power generation becomes relatively large, the efficiency of the module is relatively reduced
Therefore, there is a problem that the weight of the module increases due to the large area of the module

Embodiment Construction
[0034] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. It should be noted that detailed descriptions of known arts will be omitted if it is determined that they would obscure the embodiments of the present invention.
[0035] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be “directly on” the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no ...

A double-sided light receiving solar cell module is disclosed, and includes a plurality of solar cells connected to each other by a plurality of conductive wirings in a first direction to form each cell string, a junction box configured to collect power generated from the plurality of solar cells and supply the collected power to outside, and a plurality of conducting wires having one end connected to the plurality of conductive wirings connected to a last solar cell of the each cell string and another end connected to the junction box. The junction box and the conducting wires are disposed outside a projection area of the solar cells. The conducting wires include first directional portions extending in the first direction and second directional portions extending in a second direction outside the projection area. The second directional portions provided on at least one of the conducting wires overlap the junction box.
Description
technical field [0001] Embodiments of the present invention relate to a double-sided light receiving type solar cell module. Background technique [0002] Recently, since existing energy sources such as oil and coal are expected to be exhausted, interest in alternative energy sources instead of existing energy sources is increasing. Among various alternative energy sources, solar cells for generating electric power from solar energy are particularly attracting attention. [0003] A solar cell generally comprises semiconductor parts each having a different conductivity type (eg p-type and n-type and thus forming a pn junction) and electrodes respectively connected to the semiconductor parts of the different conductivity type. [0004] When light is incident on the solar cell, a plurality of electron-hole pairs are generated in the semiconductor portion, and the electron-hole pairs are separated into electrons and holes by the incident light. Electrons move to the n-type sem...
