The side of the cell with the gate electrode is the positive electrode, and the other side with the aluminum bottom electrode is the negative electrode.
A single solar cell cannot be used directly as a source of energy. To realize a power supply, several individual cells must be connected in series, in parallel and tightly sealed within the components. Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy, or send it to the battery for storage, or to promote work under load.
However, through the use of microinverters, the current source of the photovoltaic modules can be directly converted into a voltage source of approximately 40 V, which can be used forur power electrical devices in daily life.
At the same time, photovoltaic modules are constantly innovating. Since photovoltaic modules are called Made in China in the industry, they should be created in China, and then there will be improved and innovative products of photovoltaic modules, such as photovoltaic ceramic tiles and color steel tiles. photovoltaic. This type of product can directly replace traditional building material tiles and also has the function of photovoltaic modules. Once entering the general market, it will have a certain impact on photovoltaic and traditional modules. construction materials.
The negative electrode of the solar cell is blue because it is covered with an anti-reflective film on one side. As for the series connection, of course the positive pole of battery 1 is connected to the negative pole of battery 2, the positive poleof battery 2 is connected to the negative pole of battery 3, and they are connected hand in hand. Remember that the light receiving surface is the negative electrode, so the glass surface is the negative electrode and the back plate surface is the positive electrode.
