Solar panels are devices that use solar energy to convert light energy into electrical energy. Its working principle is based on the photovoltaic effect of semiconductor PN junctions, which can convert solar energy into electrical energy and provide power for various electronic devices. The following is the working process and composition structure of solar panels.
Solar panels
The working process of solar panels can be divided into the following steps:
Absorbing solar energy: Solar panels absorb sunlight through the solar cells inside. Most solar cells are single crystal or polycrystalline, usually dark blue or blue in color. The conversion efficiency of single crystal solar cells is usually higher than that of polycrystalline silicon solar cells.
Generate current: The absorbed sunlight shines on the semiconductor material of the solar panel, causing a voltage difference in the PN junction, thereby forming current.
Collecting current: The generated current is collected by the collector and then transmitted to the electronic device through the connection line of the solar panel.
Storage of electrical energy: Collecting electrical energy can also be stored, for example, when solar panels are used in sunlight, excess electricity can be stored in the battery first.
Solar panels
The structure of solar panels mainly consists of the following parts:
Semiconductor materials (solar cells): This is the core part of a solar panel, usually made of materials such as silicon, selenium, copper, etc., which converts sunlight into electricity
Collecting electrode: This is a metal electrode used to collect current.
Wire: used to transmit the collected current.
Support structure: used to support solar panels.
At the same time, the application range of solar panels is very wide, such as providing power for various electronic devices in household, commercial, and industrial fields, such as lamps, televisions, computers, refrigerators, etc. In addition, solar panels can also be used to provide electricity for electric vehicles, satellites, etc.
With the continuous development of technology, the efficiency of solar panels continues to improve, and the cost also continues to decrease. Therefore, their application prospects are very broad. In the future, with the continuous development and promotion of renewable energy, the application of solar panels will become more widespread.If you want to know more about solar panels, please contact us, the solar panel manufacturer – Huanqi Technology (Shenzhen) Co., Ltd.
