Embodiment Construction
[0062] Hereinafter, the present invention will be described with reference to specific embodiments as shown in the accompanying drawings. However, the invention is not limited to the specific embodiments described in the following detailed description and shown in the accompanying drawings. Rather, the illustrated embodiments illustrate only a few aspects of the invention, the scope of which is defined by the claims.
[0063] Other modifications and variations of the invention will be apparent to those skilled in the art. Accordingly, this description is to be considered as including all modifications and / or variations of the present invention, the scope of which is defined by the claims.
[0064] The drawings show a Cartesian right-handed coordinate system, wherein the z-axis represents the vertical direction, and the xy plane should be understood as a horizontal plane orthogonal to the direction of the z-axis. Thus, a direction, axis or plane will be said to be "vertical" ...

Abstract
The present invention proposes a back-contact backsheet for a photovoltaic module including back-contact cells and a manufacturing method thereof. The back-contact backplane includes an insulating substrate to which connection circuits are attached. The back-contact backsheet also includes at least one region recessed toward the air side of the photovoltaic module. The recess process is performed in the portion of the back-contact backplane including the connection circuit. Then, a via hole is formed in the recessed area to bring the surface of the connecting circuit exposed towards the inside of the photovoltaic module into communication with the face of the back-contact backsheet facing the air side of the photovoltaic module. The transmission part of the connection element, such as the rod of the rivet, can be introduced into the through hole, so that the contact part of the connection element, such as the head of the rivet, is attached and electrically connected to the connection circuit exposed towards the inside of the photovoltaic module. surface. Thus, the connection circuit allows the exchange of electrical signals between the photovoltaic module embedded in the back-contact backsheet and the outside.
Description
technical field [0001] The invention relates to the field of photovoltaic modules comprising back contact cells. In particular, the present invention relates to a novel back-contact backsheet for photovoltaic modules and a method of manufacturing the same. And more specifically, the present invention relates to a back-contact backsheet for transmitting electrical signals to the outside of a photovoltaic module in a simple and efficient manner and a method of manufacturing the same. And more particularly, the present invention relates to a back-contact backsheet that allows terminals for electrical connection toward the outside of a photovoltaic module to contact a connection circuit of a photovoltaic cell from a surface exposed toward the inside of the photovoltaic module, and a manufacturing method thereof. Background technique [0002] Solar cells are used to convert sunlight into electrical energy by means of the photovoltaic effect. Thus, solar cells are one of the mos...
