An embodiment relates to a solar cell and a manufacturing method thereof.
Recently, as the demand for energy increases, development of solar cells for converting solar energy into electrical energy is in progress.
In particular, CIGS-based solar cells, which are pn heterojunction devices having a substrate structure including a glass substrate, a metal back electrode layer, a p-type CIGS-based light absorbing layer, a high resistance buffer layer, an n-type window layer, and the like, are widely used.
In addition, as the photoelectric conversion efficiency of solar cells is improved, many solar power generation systems with photovoltaic modules have been installed outside of commercial buildings as well as in residential applications.
In order to improve the performance of such a solar cell, researches for improving the light receiving efficiency are in progress, and the appearance and display function of the solar cell are also important.

The solar cell according to the embodiment includes a plurality of back electrode patterns spaced apart from each other on a substrate; A light absorption layer pattern having a contact pattern for inter-electrode connection and a separation pattern for dividing into unit cells on the substrate on which the rear electrode pattern is disposed; A front electrode pattern disposed on the light absorbing layer and spaced apart from the separation pattern, wherein the front electrode pattern is inserted into the contact pattern to be electrically connected to the back electrode pattern and inserted into the contact pattern; A part of the front electrode pattern is in contact with the substrate.
A method of manufacturing a solar cell according to an embodiment includes forming a plurality of back electrode patterns spaced apart from each other on a substrate; Forming a light absorbing layer including a contact pattern for connection between electrodes on the substrate on which the rear electrode pattern is disposed; And forming a front electrode pattern on the light absorbing layer, and then forming a separation pattern for dividing into unit cells, thereby forming a front electrode pattern spaced apart from the separation pattern. And a portion of the front electrode pattern inserted into the contact pattern to be electrically connected to the back electrode pattern and inserted into the contact pattern.
The solar cell and the method of manufacturing the same according to the embodiment are formed such that the width P2 of the contact pattern overlaps a part of the width P1 of the rear electrode pattern, thereby easily adjusting the transmission region of the solar cell.
That is, the width P1 of the rear electrode pattern is sufficiently wide, and then the width P2 of the contact pattern is adjusted to form as many transmission regions as desired.
In the description of the embodiments, where each substrate, layer, film, or electrode is described as being formed "on" or "under" of each substrate, layer, film, or electrode, etc. , "On" and "under" include both "directly" or "indirectly" formed through other components. In addition, the upper or lower reference of each component is described with reference to the drawings.
