Patent US10249770
Issued 2019-04-02
Solar Cell Module
The solar cell module according to the present invention includes: a supporting substrate; a back electrode layer arranged on the supporting substrate; a light absorbing layer arranged on the back electrode layer; a front electrode layer arranged on the light absorbing layer; and a bus bar arranged to be in contact with the top and side surfaces of the back electrode layer. In the solar cell according to an embodiment, the bus bar is arranged to be in contact with the top and side surfaces of the back electrode layer, which enables charge transfer both in the direction of the top surface and in the direction of the side surface, thereby facilitating the transfer of charge moving on the back electrode layer in the direction of the bus bar. Accordingly, the solar cell module according to an embodiment can increase the amount of charge transfer from the back electrode layer to the bus bar, thereby improving the efficiency of the solar cell module overall.

- 1. A solar cell module comprising:
a support substrate; a back electrode layer on the support substrate; a light absorbing layer on the back electrode layer; a front electrode layer on the light absorbing layer; and a bus bar, wherein the back electrode layer is configured to be formed with a groove upon which a portion of the bus bar is disposed, the groove being formed by a top surface of the back electrode layer on the support substrate, and first at second lateral surfaces of the back electrode layer, wherein the bus bar is in contact with a top surface and the first lateral surface of the back electrode layer, and the second lateral surface of the back electrode layer is exposed by the groove; and wherein top surface includes molybdenum diselenide (MoSe2), and the first and second lateral surfaces each includes molybdenum (Mo) and molybdenum diselenide.
