Embodiment Construction

[0020] In the description of the embodiments, it will be understood that when a substrate, layer, film or electrode is referred to as being "on" or "under" another substrate, another layer, another film or another electrode, it may be "directly "ground" or "indirectly" on the other substrate, another layer, another film or another electrode, or one or more intervening layers may also be present. Such positions of the layers have been described with reference to the drawings. The size of each element shown in the drawings may be exaggerated for clarity of explanation. In addition, the size of elements does not necessarily reflect an actual size.

[0021] In the description of the embodiments, the term "transmittance" refers to the amount of sunlight incident from outside to inside of a building through a solar cell module.

[0022] figure 1 is a sectional view illustrating a section of a solar cell according to an embodiment. see figure 1 , The solar cell according to the ...

Abstract

A solar cell and a solar cell module using the same are disclosed. The solar cell includes: a back electrode on a support substrate; a light absorbing part on a top surface and one side of the back electrode; and a front electrode on a top surface and a side of the light absorbing part. on one side and in direct contact with the top surface of the support substrate.

Description

technical field [0001] Embodiments relate to solar cells and solar cell modules using the same. Background technique [0002] Recently, because of severe environmental pollution and shortage of fossil fuels, demands for and interest in new renewable energy sources have been increasing more and more. In this regard, the solar cell is focused on as a non-polluting energy source for solving future energy problems because it causes little environmental pollution and has a semi-permanent lifespan, and there are unlimited resources for the solar cell. [0003] A solar cell may be defined as a device for converting light energy into electrical energy by using the photovoltaic effect that generates electrons when light is incident on a P-N junction diode. Solar cells can be classified according to materials constituting junction diodes: silicon solar cells; compound semiconductor solar cells, which mainly include group I-III-VI compounds or group III-V compounds; dye-sensitized sol...
