Abstract
The solar cell module includes a plurality of solar cells connected to each other electrically, a sealing member provided to surround the solar cells, a front cover disposed on the sealing member, a sealing member, and a side cover An electrically grounded frame and a ground member interposed between the sealing member and the front cover and electrically connected to the frame.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell module, and more particularly, to a solar cell module including solar cell cells electrically connected to each other.
There have been many studies on the development of energy sources that can reduce environmental pollution due to depletion of existing fossil energy resources such as petroleum and coal, substitution of safe energy source as an example of Fukushima nuclear power plant accident, and global warming problem Among them, solar energy using solar light can be used indefinitely, and especially a lot of research is going on.
Photovoltaic solar cells use photovoltaic effect to convert light energy into electrical energy. Typical commercial solar cells are p-type and n-type semiconductors, Electrons and holes generated by the light irradiation with the front and rear electrodes are separated and collected in the electrode. Whereby the unit cells of the solar cell module are formed.
However, since the voltage and current generated in one solar battery cell are insignificant, a plurality of solar battery cells are connected in series or in parallel to obtain an output, and then packaged for outdoor use, and this form is called a solar battery module.
As the solar cell module is used for a long time, deterioration of the efficiency of the module of the solar cell may occur.
In particular, the potential induced degradation (PID) has been known to cause deterioration of silicon solar cell modules in recent years. That is, when the solar cell modules are connected in series, a high voltage of 600 V or more is generated, and a potential difference is formed between the frame inside the module having high voltage and the grounded module frame.
In this way, a leakage current is generated between the solar cell and the module frame due to the potential difference, and the leakage current can be accelerated according to the operating environment (temperature and humidity). The accelerated leakage current is accompanied by the movement of Na ions in the glass to the solar cell. As a result, the efficiency of the solar cell decreases and the power of the installed module decreases. (PID) phenomenon of crystalline silicon solar cell module, Bae Soo Hyun, Journal of the Korean Institute of Materials Science, Vol. 24, No. 6 (2014)).
SUMMARY OF THE INVENTION An object of the present invention is to provide a solar cell module capable of suppressing a piadie phenomenon and preventing deterioration.
A solar cell module according to embodiments of the present invention includes a plurality of solar cells electrically connected to each other, a sealing member provided to surround the solar cells, a front cover disposed on the sealing member, An electrically grounded frame provided to surround the side of the front cover, and a ground member interposed between the sealing member and the front cover, the ground member being electrically connected to the frame.
In one embodiment of the present invention, the ground member may be made of a light-transmitting conductive material. Here, the grounding member may include at least one of a transparent conductive oxide, a graphene, and a conductive polymer.
According to an embodiment of the present invention, there is provided a protection member interposed between the frame and the sealing member to suppress contamination of the sealing member, and the ground member is electrically connected to the frame through the protection member do.
According to embodiments of the present invention, generally, an upper portion of a front cover made of glass is in contact with an electrically grounded frame, and a lower portion of the front cover is electrically connected to the grounded ground member. Therefore, the upper and lower portions of the front cover all have the same ground potential. Thus, generation and migration of metal ions, such as sodium ions, caused by a potential difference from the front cover can be suppressed by interposing the ground member between the front cover and the solar cell.
In other words, as the upper and lower portions of the front cover are equipotential, a voltage is not applied to the inside of the front cover, so that the movement of metal ions inside the front cover can be suppressed.
