Electrode bonding device and bonding method of solar cell

Abstract

The present invention relates to an electrode jointing device of a solar cell unit and a jointing method thereof, wherein the electrode jointing device comprises the components of: a conductive film feeding part that is provided with a belt-shaped conductive film coil on which release paper is adhered; a selection cutting-off part which is arranged on the conductive film feeding part and cut off the conductive film before separating from the release paper; a discharging part which continuously discharges the release paper separated from the conductive film to outside; a binding part which binds the conductive film to the solar cell unit; a pre-jointing part which pre-joints the belt that is fed from the belt supplying part; a conveying part which moves the belt-jointed solar cell unit in the pre-jointing part; and a plurality of jointing parts which causes each belt to firmly joint with the solar cell unit through hot compressing. According to the electrode jointing device, after the conductive film is bound on the surface of the solar cell unit, the belt is pre-jointed. Afterwards the solar cell unit on which the belt is pre-jointed is moved to a jointing position which requires consumption of relatively longer step time, thereby realizing an effect of improving productivity.

Description

technical field [0001] The present invention relates to an electrode bonding device and a bonding method of a solar cell, and more specifically, to an electrode bonding device and a bonding method of a solar cell capable of improving productivity. Background technique [0002] Generally, solar cells used for solar power generation start from silicon or various compounds, and can produce electricity when they become solar cells (solar cells). However, sufficient output cannot be obtained with only one unit, so it is necessary to connect each unit in series or in parallel, and this connected state is called a "photovoltaic module". [0003] A photovoltaic module is composed of a backsheet, a solar cell unit, a ribbon, EVA, and glass. As the material pressed on the bottom layer of the module, the rear plate is mostly TPT (Tedlar / PET / Tedlar) type, and the tape is used as a path for flowing current, so the material coated with silver or tin-lead on copper is used. [0004] EVA ...

Problems solved by technology

As mentioned above, it is known that the conductive film can be used as a ribbon of a solar cell, but there is no description of a device for specifically bonding the conductive film to the solar cell.
