1. A solar panel can continue to be used after being cut off.
First, depending on the specific application area, some special products do not require much power generation, so they need to be cut and then assembled according to the appropriate specifications.
The second consists of; improve the utilization rate of raw materials. Solar cells are thin sheets that are extremely fragile. During the production process, it is inevitable that some products will have defects such as missing corners, cracks and skipped edges due to various reasons. not completely waste. Some pieces are still valuable.
As for the cutting size, it is based on the needs of the actual product. It mainly depends on parameters such as power, voltage, current area and shape of the electrode.
2. Simple solar panels and solar cellsThey cannot be used directly as energy sources. To realize a power supply, several individual cells must be connected in series, in parallel and tightly sealed within the components. Solar panels (also called solar cell modules) are the essential part of the solar power generation system and the most important part of the solar power generation system.
3. Solar cells are devices that respond to light and can convert light energy into electricity. There are many types of materials that can produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper selenium indium, etc. Their principles of energy production are basically the same. Now a crystal is used as an example to describe the process of producing ph energyotovoltaic. Crystalline P-type silicon can be doped with phosphorus to obtain N-type silicon, forming a PN junction.
When light irradiates the surface of the solar cell, part of the photons is absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to migrate and become free electrons which gather on both sides of the P-N junction to form With the potential difference, when the external circuit is connected, under the Under the action of this voltage, a current will flow through the external circuit to produce a certain output power. The essence of this process is as follows: the process of converting photon energy into electrical energy.
