Solar power generation is a power generation technology that produces electricity by converting the light energy of the sun. It uses solar cells that generate electricity through the photoelectric effect when exposed to sunlight. Solar power generation largely consists of modules composed of solar cells and power conversion devices.

In general, solar cells can increase voltage by tying several small cells together in series. This method can easily increase the voltage and improve power generation efficiency, but if part of the solar cell is blocked by foreign substances such as leaves and does not receive sunlight, the output of the entire module is greatly reduced. In the extreme, the output of the entire solar cell can drop close to 0 just by completely blocking one cell.

Accordingly, a method of minimizing the impact on the overall output of the solar cell by using a bypass diode to bypass the hidden cell is being used. Patent Document 1 is a bypass diode for solar cells. By designing the solar cell substrate to include a bypass diode, the method does not significantly change the output of the entire solar cell even when part of the solar cell cell is obscured by foreign substances. Begin. This method can be applied to most solar cells.

However, this method has the risk of damaging the board or causing a fire due to excessive heat when current is concentrated in the bypass diode, so improvements are required to prevent fires.

Accordingly, a method of minimizing the impact on the overall output of the solar cell by using a bypass diode to bypass the hidden cell is being used.

The solar power array module 1 according to an embodiment of the present invention is a part of a solar power generation device, and includes the solar cell 4100 and the solar cell module 4000, which is a combination of the solar cell 4100. It can be created by combining several.

Figure 2 schematically shows the solar cell module 4000 of the solar power array module 1 with a built-in bypass diode according to an embodiment of the present invention.

The solar cell module 4000 according to an embodiment of the present invention has a cathode and an anode so that the current generated in each solar cell 4100 flows in one direction, and each solar cell 4100 is connected in series. The voltage generated from each solar cell 4100 can be combined and amplified.

In addition, the solar cell module 4000 in which each solar cell 4100 is combined can be connected in series by connecting the solar cell modules 4000 with cables, connectors, etc. to increase the voltage of the solar power generation device. At this time, if one solar cell 4100 is covered by foreign substances such as leaves or bird droppings, the solar cell 4100 cannot generate power at all, which affects all solar cells 4100 connected in series. gives. In other words, the power production efficiency of the solar power generation device including the solar cell 4100 in which an abnormality occurs decreases sharply, and in severe cases, power production may not be possible. In addition, if current generated from other solar cells 4100 connected in series to the solar cell 4100, which cannot receive sunlight due to shadows caused by foreign substances, continues to flow, a fire due to heat generation may occur.

A bypass diode such as the first bypass diode 1110 is introduced to solve this problem.

The current of the solar power array module (1) without the first bypass diode (1110) flows from the solar cell module (4000.3) on the right to the solar cell module cable (4200.1). It flows through the solar cell module (4000.2) in the center and again passes through the solar cell module (4000.1) on the left through the solar cell module cable (4200.2). In this process, the central solar cell module (4000.2) includes the solar cell (4100.1) that cannot generate power due to foreign substances, so the solar cell module (4000.2) itself acts as a large resistance to generate solar power. This may lower the power production efficiency of the entire array module (1) and increase the risk of fire by generating heat.

On the other hand, in the solar power array module 1 where the first bypass diode 1110 is present, when a problem occurs, the current flows from the solar cell module 4000.3 on the right to the first bypass module ( 1000.1) and the first bypass module (1000.2), it can flow directly to the solar cell module (4000.1) on the left without passing through the solar cell module (4000.2) in the center. In other words, the defective solar cell (4100.1) can be bypassed. Through this, it is possible to preserve the efficiency of the power generated by the solar power array module 1 and prevent fire.

Meanwhile, when current passes through the first bypass diode 1110, heat is generated and there is a risk of fire. Methods for solving this problem will be described later.
